A Complete Guide To Different Types of Furnace Filters

Furnace Filters

Not all furnace and air conditioner filters are created equal. It’s often said that there are three primary types of furnace filters: cheap, moderately priced, and expensive. This would be factoring in only one aspect – sticker price – rather than looking closely at factors such as construction quality, useful lifespan, effectiveness at filtering out air contaminants and allergens, and other even more important considerations. 

In reality, there are many types of air filters (with a number of smaller variations between them). Different filters work differently and with varying degrees of success on different kinds of jobs. You want the cleanest indoor air regardless of what may be happening outside, so choose the most effective filter for the job, as outlined in this post.

First, let’s understand the Furnace Filter’s job. 

Filters used on furnace blower fans prevent clogging by protecting them from most of the dirt that is pulled into them by your furnace. In order to achieve this efficiently, the furnace filter traps dirt particles, thus preventing them from circulating throughout your home. However, what type of furnace filter do you choose will affect its life and performance. 

Types of Furnace Filters

To begin learning about furnace filters, let’s first discuss the impact of HVAC filters and the materials used to make them. 

HEPA Filters

Usually, HEPA filters are used in separate air purifiers, but in some homes, they are integrated into the central air system, which keeps the air near the furnace clean. Some HEPA filters use ultraviolet light to kill live pathogens, which denatures and neutralizes cellular organisms as they traverse the filter. Others use activated carbon to boost their efficacy even further. High-efficiency particulate air, or HEPA, filters capture up to 99% of contaminants larger than 0.3 microns. They are excellent at eliminating indoor pollutants and create a healthier environment in your home.  

Fiberglass/Synthetic Filters

Fiberglass or synthetic furnace filter is inexpensive and disposable. The filters catch up to 80% of particles 50 microns or larger and 25% of particles between 3 and 10 microns in size. Using fiberglass/synthetic filters prevents dust and dirt from building up on heat exchangers, motors, and other parts of the system. These filters collect larger particles, keeping your furnace components clean. It also allows maximum airflow in your system, but they do not filter out harmful contaminants that can cause health problems for you in long-term. 

Polyester Filters

These filters come in medium sizes and are made of high-quality materials. Polyester filters trap between 80% and 95% of large particles. Four times more expensive than fiberglass or synthetic filters, polyester filters offer better protection against pollutants that may cause health problems. 

Pleated Filters

Designed with pleats, pleated filters offer a greater surface area for filtering. They are usually made of tightly woven polyester or cotton. A fiberglass filter has a weave that is loose enough to let you see through it, while a pleated filter is more solid-looking. The MERV ratings of these rugs vary from 6-12, depending on how tightly they are woven. You’ll also need to replace this filter every one to three months, just like other disposable filters. As you raise your filter’s rating, the harder it has to work, so you will likely see more frequent replacements. 

Electrostatic Filters

Electrostatic filters filter air by using fibers that charge themselves to attract particles. Depending on the requirements of your furnace, you can purchase disposable or washable electrostatic filters. MERV ratings for washable filters range from 4 to 10, and they last a great deal longer than average filters. When maintaining a washable filter, you must wash it with soap and water and let it dry completely before reinstalling it. Mold and mildew can grow if you install it before it has completely dried.

Carbon Filters

Carbon filters filter the air using carbon, or charcoal. Carbon is highly efficient at trapping gases in the air. Pollutant molecules attach to carbon molecules through a process called adsorption. If you’re choosing a carbon filter, make sure it has a high carbon content and is activated. An activation process increases the surface area of carbon molecules, making them more effective. More carbon means more pollutants that the filter can absorb.

Also, consider the thickness. A thicker carbon filter will capture more particles than a thinner one. Since the air spends more time in a thicker filter, it gets cleaner. We call this dwell time.

What to Look for When Purchasing Filters

It is recommended that disposable furnace filters be replaced every three months. Depending on the filter, it may also need to be replaced every few weeks. Further, the air you breathe inside and outside your home may require you to replace your filter more frequently. Consult the filter manufacturer’s recommendation to determine the replacement frequency.

Changing your filter regularly will ensure that your furnace is functioning properly. You will also enjoy excellent indoor air quality and low energy bills. As an added benefit, regular maintenance will ensure that your furnace’s filter isn’t clogged and will improve its lifespan.

What Air Purifier Do I Need and Why?

choose the right Air Purifier

With ever increasing levels of pollutants and allergens in the air, air purifiers have just about become an absolute necessity. Environmentally natural surroundings are becoming harder to find in most metropolitan cities due to the increased pollution levels. As a result, air purifiers serve as a relief from breathing in toxic air and the result is a vast improvement of your IAQ (Indoor Air Quality). All of these factors may result in improved health for you and your family!

However, choosing an air purifier is quite complicated. It is possible to identify air purifiers using charts, studies, and certifications. Be sure you understand all the data before making your decision. Here are some tips on choosing an air purifier.

Why Do You Need an Air Purifier?

Compared to outdoor air, indoor air is usually found to be more harmful, especially over longer periods of time (such as being indoors during the cold winter months). The air quality in homes can be affected by numerous household products such as deodorants, cleaning products, and even inkjet printers. Those who suffer from dust allergies, asthma, or other respiratory disorders, as well as small children, should consider taking advantage of an air purifier. Air purifiers remove allergens, pollen, dust, pet hair & dander, plus many other pollutants that are invisible to the naked eye. There are also air purifiers that absorb unpleasant odors emitted by things like paint and varnish.

How To Choose an Air Purifier

The number of air purifiers in the market today is so vast, with different features and functions, that choosing one can prove difficult. However, you can make it easier with this air purifier buying guide, which can help even if you don’t have expert assistance.

  • Measure the size of the room in which you will install the air purifier.
  • Select an air purifier with a high enough CADR for the room.
  • Choose the type of filter you will need, paying attention to specific contaminants.
  • Ensure that you can live with an air purifier. Costs and noise are factors to consider.
  • Make sure that your air purifier does not contribute to indoor air pollution. Avoid ozone-producing air purifiers at all costs.

Which Air Purifier To Choose?

If you want to find an air purifier that works for you, you should choose one with the right technology. Typically, high-quality air purifiers can capture 99.7% of all particles at 0.1 microns and smaller. US Home Filter’s air purifiers and AC filters are the industry’s finest, offering outstanding performance at a low energy cost and almost silent operation.

  • Silent Air Purifiers:

One important consideration that shouldn’t be overlooked are noise levels, especially when placing an air purifier in the bedroom. So, you should consider high clean air delivery at very low noise levels.

US Home Filter air purifiers offer among the most silent air purifiers available, and they are the only ones that deliver high amounts of clean air at low levels. They are mostly used in social settings or at nighttime. Air purifiers from US Home Filter are so quiet that you might not even notice they are turned on!

In order to achieve near-silence, the technology used charges particles in the air first so that they will more easily attach to the filter medium. As they are attracted to the filter like a magnet, we can make our filters less dense. In turn, the fan does not have to work so hard to carry the same volume of air, which results in an extremely quiet operation.

  • Energy-efficient Air Purifiers:  

Energy efficiency is another major concern. On average, a medium-size air purifier consumes 50 watts of electricity. Since their fans consume the most power, air purifiers have the most power consumption. Using the maximum fan speed for 12 hours a day would cost $2.15 a month.

A US Home Filter air purifier does not need to work as hard, which helps our air purifiers to utilize energy more efficiently than others. They typically use the same amount of electricity as a light bulb.

  • Air Purifiers for Smoke and Exhaust

If you live in an area where there is a lot of automobile traffic, or you happen to be a smoker, you may be exposing children to airborne particles that are particularly harmful to their developing lungs. If you use an activated carbon filter from the US Home air filter, the machine will effectively remove cigarette smoke, odors, pollutants, and smog, as well as airborne chemicals.

US Home filters are designed to last for many years without clogging due to the combination of the weight and volume of carbon, as well as the low density and large surface area of the mechanical filter medium. Using an advanced HEPA filter will help you remove smoke and gas four times faster.

What Size Air Purifier Should I Buy?

It is recommended you choose an air purifier that changes the air roughly five times per hour. It’s okay to oversize your air purifier a bit, but you shouldn’t undersize it.

To figure out what size would be exactly right for your room, measure the room and then check the CADR (or Clean Air Delivery Rate). CDR measures how much clean air an air cleaner produces per minute by taking into account the area of the room. This shows how well dust, pollen, and smoke, three of the most common indoor pollutants, are removed from the air.

Air purifiers have CADR ratings that indicate how much particulate matter they remove from the air. You usually want a large CADR number when your room is larger. There is no industry standard for the CADR number associated with the size of a room. As a result, some products will indicate the recommended room size on their packaging.

Does it Cost Extra To Operate?

An air purifier might add another layer of expense to your budget, as an air purifier that runs 24 hours a day will obviously result in an increase in your household’s utility bill. Therefore, it is recommended that you choose a purifier that is Energy Star rated. Energy Star is a program that ensures the device meets the EPA’s strict energy efficiency standards.

The second layer of air purifier costs pertains to its maintenance. The cost of replacing filters is the largest part of operating an air purifier. When buying an air purifier, shop around and compare the cost depending on the size you need.

You can also contact US Home filter for detailed assistance on maintenance and what type of Air Filter your home needs.

When To Change Your Air Filter? Top Signs To Consider

air filter

HVAC filters are obviously an important part of maintaining high indoor air quality in your home or office, but there are many factors to consider. A variety of factors impact the need to change your air filter, including both your environment (including indoor and outdoor pollution) and the quality of the filter you currently have installed. Fortunately, there are a few signs that indicate your HVAC filter should be replaced. 

Why Your Home Air Filters Need to be Changed

1. Visible Dirt & Dust

A small amount of dirt on your air filter is not a cause for concern. However, if dirt blocks both the surface and the material of an air conditioner’s filter, it should be replaced and is most likely long overdue. Having any dirty filters and/or ductwork can result in HVAC problems on many fronts.

When all the dirt on the filter blocks the airflow, your air conditioner will no longer be able to cool down your house properly an efficiently.  A small restriction on your cooling system’s filter caused by dirt and dust can result in a drastically reduced cooling performance.

In turn, your air conditioner will have to work harder, resulting in your having to pay much higher energy bills than normal. Additionally, your HVAC system may require extra maintenance. As a result of dust on the indoor coils, the cooling process becomes compromised. This can cause serious damage to the compressor, which is very expensive to replace, so you must consider replacing the filter it as soon as possible. 

2. Musty or Moldy Odor

A musty odor is another indicator that it’s time to update or change your air filter. If you have any furry creatures around your home, you may have noticed that they shed throughout the summer. 

Pet dogs and cats have a tendency to shed their fur and this results in bad odors. It may even smell musty if they linger around your inside of your house. The odor is sometimes also caused by mold and mildew in addition to pets. This bacterial growth emits a very unpleasant odor.

If your filter isn’t changed, all of these odor-causing contaminants will return to your home. Fortunately, just routine cleaning and maintaining your AC filter properly will often times fix the problem.

3. Allergies and Asthma

Another sign that your home air filters need replacing is if you or anyone in your household suffers from allergies or asthma. Keeping your old air filter too long can cause allergens to accumulate. You might actually find that your indoor air is more polluted than the air outside.

The next time you find yourself sneezing constantly, feeling stuffy, or your asthma flares up, it might be time to check your air filter. You should be aware that leaks in your ductwork can also lead to the influx of these allergens, so call a reputable HVAC contractor.

As the air filter becomes dirty and full, those irritating allergens will not be captured as efficiently. Allergies are most common in the spring and summer months. In cases of allergies, it is recommended you replace your air filter more often, every 30 to 60 days.

4. High Electricity Bills

When the electricity bill starts to climb, sometimes it’s difficult to figure out the exact reasons. Perhaps the AC system is malfunctioning, or an appliance isn’t working properly? We can expect higher electric bills in southern states like Florida during the summer since we rely heavily on air conditioning during the warm months. When your power bill is higher than normal, you may find that you’re dealing with a dirty air conditioning filter. As a result, preventative HVAC maintenance is critical. Keeping your HVAC system in good condition allows it to operate more efficiently, thus consequently, you will pay less for energy bills.

5. Air Is Not Cold Enough

When your air conditioner doesn’t keep the room as cool as it normally does, you may need to change a filter. Depending on the situation, this may mean that your HVAC system isn’t working properly, and that maintenance is required. When the HVAC air filter is clogged with debris, it hinders air circulation severely, thereby reducing the number of times cold air can be circulated in the building.

Air Conditioner vs. Air Purifiers: How They Differ and Why Do You Need Air Purifiers


Air conditioners are often actually lifesavers in areas of the country where record-breaking heat waves sometimes are raging. But did you know aside from providing us with cooling power, air conditioners can also negatively impact the air quality inside your home sometime Let’s understand how this can happen.

How Does An Air Conditioner Work?

Household air conditioners come in three main types: central units, window units, and portable units. You may choose one or more of these based on the design of your home or business, and the climate where you live or work.

A central air conditioning system is a part of your home’s heating, ventilation, and air conditioning system (HVAC). All the rooms in your home are cooled by just one large condensing unit, typically located outside. The air conditioner also contains a fan that moves cool air into your home through your air ducts and into vents installed on the ceiling, walls, or floors.

Window air conditioning units use the same cooling components as central air conditioners, but the entire system is self-contained in the window unit.  Air conditioner units that are installed in windows are generally the most efficient and the cheapest. You can use them in any room with unobstructed slide-to-open windows, plus you can move them around as needed.

Portable air conditioners are freestanding units that are easy to move from room to room. Although the units contain an outdoor exhaust hose, you still need to place them near a window to allow that exhaust to escape.  A hose that’s not vented outside will let hot air into your house and the air conditioner will not have the capacity be able to cool it effectively.

How Do Air Conditioners Affect You?

Using air conditioners can cool your indoor air, which will make it feel fresh while decreasing humidity levels. However, they aren’t intended to catch all of the airborne pollutants that may exist in your home.

Indoor air pollution can come from many sources. The most common contaminants are pollen, mold, wildfire smoke, pet dander, cleaning chemicals, and cooking byproducts. Depending on their nature, these pollutants can be particles and gases, including volatile organic compounds (VOCs). Since many people spend most of their time indoors, they should know how to protect their indoor air quality and, thus, protect themselves from possible harm.

No matter if the air conditioner is built into the HVAC system or installed separately, it should always incorporate filtration. There are ready to incorporate filters or custom filters you can order that can trap larger airborne pollutants, including dust and pet hair. Filters have different MERV ratings, which determine how much, and which kind of pollutants are trapped. 

Minimum Efficiency Reporting Value indicates how well a filter can capture particles in the range of 0.3 to 10 microns. To decrease the risk of allergies, replace your HVAC filter each month using a MERV 13 filter or the highest rating your HVAC system can support, as recommended by the United States  Environmental Protection Agency (EPA) The ideal usage of these filters would be to trap viruses and even smaller particles if possible.

What is the Difference Between Air Conditioners and Air Purifiers? 

Despite the fact that air purifiers and air conditioners have similar features, like fans, filters, and vents, they serve very different purposes. Air conditioners let you cool the air in your home and maintain a certain temperature within. Air purifiers improve indoor air quality, but they do not regulate your home’s temperature.

Unlike air conditioners, air purifiers are intended to run constantly. This allows them to change the air in the room on a regular basis, eliminating contaminants as they travel through the filters. Whether your air purifier’s filter can remove particulate matter, gaseous pollutants, or both depends on the type of filter you choose.

Air purifiers may also use HEPA filters to trap airborne particle pollution, like some HVAC systems. Nevertheless, they may not be effective against gaseous pollutants. Carbon filters are another common technology used in air purifiers, and they produce the opposite result. The filtration systems can capture harmful gases, but they are powerless to capture fine particles.

Why Should You Upgrade Your HVAC Filter?

Normally, an air filter is made of a spun fiberglass material or pleated paper or cloth enclosed in a cardboard frame. A filter’s basic function is to keep the air circulating through your heating and cooling system clean. Filters are designed to capture and hold a variety of contaminants that can affect your health and comfort, including:

  • Dust and dirt
  • Pollen
  • Mold and mold spores
  • Fibers and lint
  • Metal, plaster, or wood particles
  • Hair and animal fur
  • Bacteria and microorganisms

Upgrading your HVAC filter will prevent debris from building up in your system. Thus, the air inside your home is also clean and healthy to breathe.

The reason your home is full of pollutants is commonly because of dirty air filters. They not only contaminate the surrounding air, but also allow bacteria to grow inside your HVAC system. This leads to ever-increasing levels of dangerous pollution in the air that you and your family breathe in your home.

So be sure your filters are changed regularly/monthly. You can inspect the filters visually yourself to determine whether they are dirty or clogged. Try holding the filter up to a light source. If it can’t be seen through, it probably needs to be replaced.

What’s more, the team at US Home Filter specializes in providing quality air filters and filtration solutions for homes. We offer both standard-size air filters and custom-size air filters. Our high-quality products and excellent service will ensure that you will become one of our many satisfied customers!

Why Is HVAC Preventative Maintenance Important?

hvac maintenance

Maintaining your home HVAC system will ensure consistent, reliable performance and comfort for many years. To prevent malfunctions and breakdowns, especially during the peak of the heating or cooling seasons, preventive HVAC maintenance should be performed at least annually whether you use a furnace, central air conditioner, or heat pump. 

Maintaining your HVAC system preventatively is equally important for your business. A defective heating or cooling system in a commercial building can bring with it anything from minor inconveniences to total disasters. The least that can happen is that the employees and customers will suffer discomfort. At worst, a malfunctioning HVAC system could cause spoiled goods, frozen water pipes, flooding, and result in major facility damage and costs. Plus the costs of replacing your unit.

In order to avoid these problems and make sure that your heating and cooling system is functioning optimally, contact your nearby HVAC service provider and arrange for a preventative maintenance inspection. It’s best to schedule preventive maintenance every year. If you have a cooling system, its preferable to schedule the maintenance in the spring. If you have a heating system, schedule maintenance in the fall.

Pre-season maintenance gives you ample time to perform any repairs before a major weather change, including a number of other advantages like:

Improved Performance

Almost immediately after the first use, your equipment begins to wear out. As moving parts wear out, they break. Belts may crack. Bearings may require lubrication. If you deal with frail parts before seasonal use, you will avoid the frustration and expense of a mid-summer or mid-winter malfunction.

Compressors can suffer serious problems due to certain issues. You may experience freezing coils due to both low refrigerant levels and/or dirty coils. If this issue isn’t handled in a timely manner, permanent damage may result. During the summer months, each of these problems can contribute to higher cooling bills. A little maintenance can save money while maintaining a comfortable house. Its important, sometimes requiring the help of experts, to ensure that your system functions properly.

Improving Your Indoor Air Quality

Having a properly functioning HVAC system will keep your home’s air quality high. HVAC systems filter out air pollutants to ensure that you and your family breathe clean air. Although you may not think that the danger exists indoors, the EPA estimates that indoor pollution levels typically exceed pollution levels outdoors by two to five times. It takes a lot of effort for your HVAC system to filter out allergens and pollutants, so the more efficient the system, the better your air quality will be.

US Home Filter recommends an air quality assessment for an in-depth analysis of what influences your household’s air quality. There are several equipment options available to properly control mold and improve indoor air quality. These include UV lights to destroy bacteria and mold growing on your coils, dehumidifiers to keep your house dry, and air purification systems to filter out mold spores, volatile chemicals, and pathogens. 

Energy Usage Concerns

A tune-up is a great time to talk to an expert about your high energy bills. A home maintenance service can improve its performance, but there are additional reasons why costs are high, and comfort levels are low. Your technician may suggest some changes to help you reduce costs and improve your comfort. It can be difficult to heat and cool a multi-level home efficiently. This can be solved with zoning systems. If your system is not sized properly, then your home will suffer. Hence, you can count on us to give an overview of such issues as well as relevant solutions. Call US Home Filter to arrange your tune-up today.

Reducing the Cost of Repairs

Maintaining an air conditioner regularly avoids the need for urgent repairs. In preventive maintenance, a skilled HVAC technician can often identify potential problems before they turn into costly ones. It is much more affordable to repair many malfunctions or normal wear and tear when detected early. If you do not regularly service your HVAC system, small issues can quickly become large ones. Many people don’t call an HVAC technician until their system fails, which can be an expensive fix. To detect and fix problem areas early before they become a system failure is just one of the many reasons for system maintenance.

Increased Safety

The primary reason you should maintain your home is to make it safer for you and your family. HVAC maintenance will keep you and your family from becoming poisoned by carbon monoxide. There is a good possibility your technician will check for carbon monoxide leaks, which can be deadly for you and your family. Maintenance can also help prevent malfunctions in the most extreme weather conditions. When you travel for the holidays, for instance, you don’t want to worry if freezing temperatures will damage your home’s heating system. There is no one who wants to return home to burst pipes from a frozen pipe or any other disaster like that. So, don’t overlook it ever.

Extension of Your HVAC System Life

With regular maintenance, you can keep the system running longer and avoid costly system replacements. Just as having regular checkups with a medical professional is important for your health, HVAC maintenance is also essential. If you invest in a new HVAC system, you would like it to last as long as possible. Regularly maintaining your HVAC System can extend its lifespan.

Financial Savings

Your well-maintained system will use less electricity. This will save you money. You might save money if you catch an issue before it becomes a costly repair, or maybe you can use your system for several more years without having to replace it. In addition to saving money on repairs, you’ll prevent costly medical treatment for matters such as carbon monoxide and allergens. All the reasons for maintenance will improve your bottom line. The small investment you make in HVAC maintenance will save you money in other areas, including maintenance, repair, and utility costs.

Whole House Air Filter: All You Need To Know

whole house air filter

Air filters exist in a huge variety of sizes, but you’ll sometimes find that it’s challenging to find the exact one you need in a store. Air filters for the home are very common obviously, but how do I really measure the correct size? And what’s the exact MERV grade that my system requires to perform at it’s best and most efficiently? So, here’s basically everything you need to know about whole-house air filters and selecting the right replacement filters.

Why Do You Need Such a Big Air Filter?

The home air filter is perhaps the least standardized product in the world. That’s why nobody can find their size at the hardware store, and that’s why we offer such a vast array of different sizes.

Whole-house air filters are one type that can be particularly difficult to locate at local stores, as they are quite different from the usual one-inch filters. You may have heard them called whole-house air purifiers. HVAC systems include air purifiers, but they are not part of them. However, the air filters are part of your system and are not optional. 

By definition, the concept is defined by the need for only one filter per household. It’s the most common setup, but sometimes it doesn’t hold true in practice. Your whole house filter requirements depend on how your HVAC system is configured, which could differ from one system to another.

When you install Whole House Air Filter, air handler units (AHU) regulate and circulate air. Basically, it controls your air. Some houses may have multiple air handlers to regulate the temperature in different areas separately based on the house’s size. 

Whole-house systems can be installed if you have ductwork and a forced-air system.

What Do Whole House Air Filters Look Like?

A whole house filter is defined as a filter with a thickness of three inches or more. The most commonly available thicknesses are four and five inches, but three- and six-inch options are also available. They are similar to common one-inch pleated filters but have one difference. Compared to one-inch filters, whole-house filters have a much larger surface area due to the deep-v pleats that fill their nearly half-foot thick frame.  

In general, the “nominal size” of an air filter is the rounded size, based on how each dimension is rounded up or down. There is a standard undercut on one-inch filters, which means that all one-inch filters measure ¼” to ½” shorter than their nominal size, but there is no standard undercut on whole house filters. This means that two 25x20x5 filters from different manufacturers may have completely different sizes. Make sure you know the exact size you need, or you may end up with a whole house filter that doesn’t fit.

What Makes a Whole House Air Filter So Different? 

A whole house filter and a regular one-inch filter differ primarily in their longevity, in addition to their appearance. Unlike personal filters, a whole house filter does not require constant replacement due to its massive surface area. Often times the manufacturers recommend replacements every six months instead of every three, and sometimes, even once a year is sufficient. 

In order to determine how often your filter needs to be replaced, you need to consider what factors may influence the quality of your air. What is a replacement frequency for the living situation without pets? Six months should be enough. Do you have a lot of pets and live in a polluted area? It might need to be changed more frequently, like every three to four months. 

Is a Whole House Filter More Expensive?

Indeed. On average, a whole house filter costs between $25 and $35, and some go as high as $40. They cost more than one-inch air filters, but they also need to be changed less frequently and sometimes only one at a time. Despite the fact that whole-house air filters may cost more than smaller ones, you may spend less on air filters per year (depending on your house).  

Where Can You Fit the Whole House Filter? 

Unlike other air filters, a whole house filter does not fit in your wall. Air filters are put into the ductwork directly in front of the HVAC system. There are several filter varieties that fit into the housing before being installed, while others are inserted directly into a slot in the duct.

Although a whole house filter sounds wonderful, you might not actually require one. If your home uses whole house air filters, then you can use them. In the event your home doesn’t already have the system installed, you will obviously need to install a new one or upgrade your existing one. Prior to deciding to upgrade your system, you’ll need to consider the installation and upgrade costs.

Need Personal Assistance While Choosing a Whole House Filter? 

Us Home Filter provides air conditioning and heating filters to customers throughout the United States. So, once you decide you want to install a whole house filter, you might get confused on the sizes, brands, and much more. In such cases, our experts can help you. You can call us at 1-855-435-9600 or contact us online today! With us, you’ll receive high-quality filters, a large assortment to meet your needs, reasonable prices, and FREE SHIPPING for purchases within the contiguous United States. So, get in touch now!

How Do HEPA Air Purifiers Disinfect Germs Viruses and Smoke

HEPA air purifiers

In Covid-19’s fight, products such as disinfectant sprays, face masks, and touchless garbage cans, are being pushed as essential. According to medical experts, one additional item that people should be adding to their arsenal is an air purifier. A good air purifier is not only helpful in eliminating airborne dust, pollen, smoke, and other irritants but can also keep dangerous germs and bacteria at bay. 

How Does an Air Purifier Work?

Air purifiers eliminate germs, dust, mites, pollen, and other potentially hazardous particles by drawing air into a chamber and passing it through a filter. The air is returned to your house once it has been cleansed by the air purifier.

The finest air purifiers can also absorb or filter out smells like those caused by cooking or smoking. A few air purifiers also have a heating or cooling option, allowing them to function as a stand-alone fan or heater when the weather changes.

What is a HEPA Air Purifier?

HEPA filters (high-efficiency particulate air) are used in the best air purifiers to collect more particles from the air.

A standard air purifier filter has a design and filtration ability similar to that of a coffee filter. These are among the most popular air filters in today’s homes and offices. Despite being expensive and hard to locate a few decades ago, HEPA filter air purifiers are now used everywhere, from homes to automobiles, to planes to medical facilities.

True HEPA air purifiers capture 99.97% of particles as small as 0.3 microns, including allergens and odors. A HEPA-type filter, on the other hand, can catch 99% of particles 2 microns and larger, such as pet dander and dust. While these particles are too small to be seen with the naked eye, they are large enough to enter your lungs and cause problems.

The smaller the micron, the harder it is to filter out of the air. To put it into perspective the human eye can detect a particle that is approximately 10 microns. Bacteria can be as small as 0.3 microns, which is why 0.3 micron industrial HEPA filters are used in pharma companies


Can an Air Purifier Help With Viruses?

It’s both a “yes and no” answer. According to the CDC (Centers For Disease Control And Prevention), these units can help “reduce the airborne concentration of the virus that causes, for example, Covid-19 (SARS-CoV-2), lowering the risk of transmission through the air.” 

HEPA filters will catch 99.97% of particles with a diameter of exactly 0.3 microns. Particles of that size are ideal for passing through the filter’s fibers, but bigger and smaller particles collide with the structure as they flow through the air. 

Although the new coronavirus is 0.125 microns in diameter, the droplets it travels in – when individuals cough, talk, or breath – are initially bigger, approximately 1 micron in diameter. Experts say it’s a size that HEPA filters can readily absorb.

Nonetheless, you still have to follow the usual precautions, such as washing your hands with soap and water, using hand sanitizer wearing a protective face mask when in close contact with others.

A Guide To Selecting a Portable Air Cleaner, Furnace Filter, or HVAC Filter

portable air purifier

The air quality indoors is frequently more polluted than the air outdoors, which can obviously negatively impact you and your family’s health. Some of these pollutants originate from the outdoors, while others come from indoor sources and activities including cooking, cleaning, secondhand smoking, construction materials, consumer items, and home furnishings.

As a result, the best strategies to enhance indoor air quality are to reduce or eliminate sources of pollutants and to ventilate using fresh, outside air. Filtration has also been found to be a beneficial complement to source control and ventilation in studies.

You can use an air purifier or change the filter in your furnace or heating, ventilation, and air conditioning system (HVAC) if you’re concerned about the quality of your indoor air. Portable air cleaners, often known as air purifiers or air sanitizers, are air cleaners that are meant to filter the air in a single room or area.

Meanwhile, an HVAC filter or central furnace will purify the air in every room of the house. However, when selecting an air cleaner, furnace filter, or HVAC filter, keep in mind the following:

  • A home air cleaner or filter cannot eliminate every air pollutant.

    The majority of filters are designed to filter either particles or gases. Therefore, many air cleaners contain two filters, one for particles and another for gases (inclusive of gases with odors). A typical air cleaner has only one filter, usually used for particles. Further, some air cleaners or filters are designed to target particular gases or VOCs. You can also check the specific product packaging or label for more information.

  • Replace all filters on a regular basis.

    An overloaded and dirty filter will not function properly. Air filters are things that are easily forgotten as they are usually tucked back into a closet or storage space. The key to keeping on top of regularly changing the air filters in your home is to set yourself reminders. Here are a few options:

    • Write the date you changed it on the edge of the filter.
    • Write the date to change the filter on the family calendar.
    • Set up automatic reminders on your phone.

When To Choose Portable Air Cleaners?

  • To Filter Particles in a Single Room:

    Choose a portable air cleaner with a clean air delivery rate (CADR) big enough for the size of the room or area where it will be used to filter particulates. The higher the CADR, the more particles the air cleaner can filter and the greater the service area it can cover. The greatest size area or room that an air cleaner should be utilized in is usually specified on the box. Often, portable air cleaners achieve a high CADR by using high-efficiency particulate air (HEPA) filters.

  • Choose To Filter Gases:

    Select a portable air cleaner with an activated carbon filter or another gas-filtering filter. As far as gas-removing portable air cleaners or filters are concerned, there is no commonly accepted performance rating system. Only particles are rated with the CADR system. If a considerable amount of material is utilized in the filter, activated carbon filters can be effective. With a portable air cleaner equipped with an activated carbon filter, particles and gases can be filtered.

In general, greater fan speeds and longer operating times will produce more air filters. When set at a lower speed, an air cleaner will not filter air. Since more air passes through the filter at higher fan speeds, higher fan speeds typically provide more filtration. A longer run time for an air cleaner will also boost filtration.

When To Choose Furnace and HVAC System Filters?

  • To Filter Particles Throughout a home:

    A furnace or HVAC system works to filter the air in the entire home, however, it works only when it is operating. Most HVAC systems only run during the heating season or cooling season (fewer than 25% of the time). It is more efficient to run the system for longer periods in order to get more filtration. The idea may not be feasible or desirable in many cases, since prolonged run times can lead to higher electric bills and also less reliable humidity control during the summer months.

  • Choose Only With 13 MERV Ratings or Higher:

    Filters for furnaces and air conditioners in houses are typically intended to filter particulates. Consider a filter with a minimum efficiency reporting value (MERV) rating of 13 or the highest rating the fan and filter slot of your system can support if you prefer to upgrade or use a higher class of filter.

In addition to filters, there are other devices that remove particle and gas mixtures. Usually, they are found in commercial buildings and large buildings with HVAC systems.

Covid Virus and Home Air Conditioning Filters

Research has been ongoing to understand COVID-19’s transmission and spread since it began way back in January of 2020.

CDC guidance indicates that COVID-19 primarily spreads through large respiratory droplets produced when a person coughs or sneezes, but there’s mounting scientific evidence indicating that even smaller virus particles can stay in the air and infect people as they breathe.

These risks are greatly increased in enclosed spaces with smaller particles, such as your home, where the air isn’t circulated as often, and you may be interacting directly with others.

In such a situation, the air conditioning filter in your home is the first line of defense against airborne transmission and is  the easiest to replace.

Air Cleaners and HVAC Filters

Air filters and air cleaners are equipped to remove pollutants and contaminants from the air. By purifying and cleaning the air, airborne contaminants, such as viruses, can be reduced. When extra ventilation with external air is not possible without compromising indoor comfort (temperature or humidity), or when outdoor air pollution is excessive, portable air cleaners (also known as air purifiers) can be very useful.

Air cleaners and HVAC Filters in Homes

There are a variety of air conditioning filters and cleaners available, including;

  • Air Filters and Furnace Filters

    The primary purpose of air conditioning filter and furnace filters is to prevent dirt and debris from accumulating on your system’s vital components. As a result, dust, pollen, and pet dander are collected and reduced, as well as airborne viruses. US Home Filter offers a wide range of MERV ratings and sizes to fit your specific requirements.

  • Whole House Air Filters

    A whole-house air filter is also called a residential air cleaner, a media filter, or a whole-house air cleaner. All of them protect your HVAC system, remove contaminants from the air, and improve indoor air quality. Due to the large surface area of these large filters, they only require replacing every 6-12 months.

  • Grille Filters

    The grille filters are used in return air vents, in-wall and ceiling grilles, and in-ceiling grilles as well. Ideally, the grille should extend 7 inches behind the wall. In this way, it will be possible to install the filter and let air flow through it. Compared to standard 1-in filters, grille filters offer greater airflow and efficiency due to their increased surface area and depth.

  • Humidifier Pads

    When it’s cold outside, humidity helps to stop your skin from drying out because of the furnace. Having a humidifier in your home can also help you save on energy costs! By reintroducing moisture to the air, the air can feel warmer and more comfortable despite its lower temperature.

Air Cleaners and HVAC Filters & Coronavirus

While portable air conditioning filters have not yet been proven to filter out COVID-19, there is research to support the assumption that an air purifier can filter common airborne viruses, provided the air is captured by the system.

As mentioned earlier, an air cleaner, a furnace, or an HVAC system filters the air throughout a home. It can improve indoor air quality by reducing pollutants in the air, such as viruses. HVAC filters and portable air cleaners do not provide enough protection against COVID-19. However, when combined with other best practices such as filtration can help keep people safe indoors.

To mention a few, bipolar ionization can be used in HVAC systems or portable air cleaners to produce positively and negatively charged particles. Some manufacturers market these devices for removing viruses from the air, including SARS-2-CoV, which causes COVID-19, or for disinfecting surrounding surfaces such as doors, windows, and other surfaces.

A limited amount of research has been done to evaluate this technology outside of lab conditions, as it is an emerging technology. Newer technologies are typically less well documented in terms of safety and effectiveness than older ones. Nevertheless, it can generate ozone and other potentially harmful by-products indoors, unless specific precautions are taken in the product design and maintenance.

It is also possible to supplement increased HVAC system ventilation and filtration with portable air cleaners, especially in areas where adequate ventilation is difficult to achieve. When the airflow is directed away from people, it reduces the chance that infectious viral droplets will spread from person to person.

It may not be possible to prevent viruses with air filtration methods. Keeping your hands clean and disinfecting surfaces is still essential. In the end, more infections are contracted while you’re outside (at work, shopping, etc.) than at home. However, keeping your home clean and safe from dirt must not be avoided.

Top Causes of HVAC Issues

An efficiently working HVAC system is a must for two very important reasons:
1. It maintains a certain comfort level that you choose.
2. It saves quite a lot of money on your energy or power bill.
In order to get the most efficiency, the lowest energy costs, and the longest life out of your HVAC unit, all parts of the system must be fully functional, plus well maintained. If your energy bill is rising and/or your home is not as cool and comfortable as you would like it to be, here are the some of the main causes of HVAC issues and the reasons why your AC unit isn’t working as well as it should be.

Issue #1: Dirt Buildup

HVAC System

Before overreacting and thinking that the issue(s) is something huge that’s going to cost you lots of money to fix, first check and make sure that your system is clean. If you’ve recently noticed a reduction in its efficiency, it may just simply be an excessive buildup of dirt and grime on your HVAC unit. When this buildup occurs, your HVAC unit is unable to heat or cool your home as evenly and quickly as it should, or as it did in the past. You may also notice an increase in allergy and asthma symptoms in yourself or your family as your home’s indoor air quality (IAQ) has also been greatly reduced.

The first and MOST IMPORTANT thing you can do is to make sure you are using a clean air filter. Air filters should be checked at least once a month (although some only every three months, depending upon the AC manufacturer’s directions). If they are dirty, simply change them out with a fresh clean air filter. To check if your air filter is dirty, remove it from the air conditioning unit and just hold it up to a light source. If you cannot see the light through the filter, then it’s definitely time for it to be changed. Another area to check are the heat pump condenser coils. Coils that are dirty cause a decrease in your AC unit’s air flow capacity and will greatly reduce the efficiency of your unit.

Issue #2: HVAC Equipment Age

If you’ve noticed that your home has become less and less comfortable temperature wise over the past few years, then perhaps your HVAC unit may be close to the end of its lifespan. It would be nice if HVAC equipment lasted forever, but unfortunately that’s not the case. Even with regular upkeep and perfect maintenance, you may only get a few more years on the lifespan of your unit. Most units last roughly about ten to fifteen years, and luckily, the newer models are tremendously much more efficient than the unit you likely have now. If you feel like your unit may be on its last legs, get it checked out by a professional and consider replacing it with a brand new high efficiency HVAC system.

Issue #3: Improper Installation

If your HVAC system isn’t installed properly it will not run efficiently. When this is the case, your energy bills will immediately skyrocket, plus your home is never as cool or warm as you expect it to be. It’s important that you always hire a licensed, insured professional to install your equipment.

Here are some additional HVAC issues or problems that may occur with improper installation of your AC unit:

  • Short circuit: the electric voltage is key for the unit to run properly. If it is not correct it will cause a short in the circuit.
  • Poor results: the size of your unit is also important. If a unit that is too small for the size of your home is installed, there will be problems getting the house to feel comfortable and result in uneven cooling and heating in your home.
  • Duct Leakage: If you notice temperature differences throughout your house, the ducts may not have been installed correctly. When this is the case, the ducts develop air leaks which cause drastic temperature changes from room to room.

Issue #5: Lack of Maintenance

HVAC systems work hard to continually make your home comfortable. Scheduling a professional maintenance check and cleaning is essential to make sure everything is running efficiently and correctly. These checkups can also find small problems and resolve them before they turn into major problems, resulting in both equipment failure and damage to your system. Looking for a heating and cooling contractor to inspect your HVAC system? The Department of Energy website offers instructions to help you find the right contractor for your needs.
