Reasons Your Air Filter Isn’t Cleaning Your Indoor Air

Indoor Air QualityResearch has proven that the small, microscopic, nearly invisible particulates that float around in our indoor air are not good for our health. The American Lung Association reports that airborne particles 2.5 microns or less (called fine particles) are an inhalation hazard as they are “easily inhaled deeply into the lungs where they can be absorbed into the bloodstream or remain embedded for long periods of time.” A recent study also showed that the mortality risk showed 17% increase in areas with high concentrations of fine particles. These small particles also greatly affect anyone that has asthma problems. They can trigger asthma attacks, respiratory irritation, coughing and wheezing.

What is the best way to make sure your indoor air is as clean as possible? The first thing to do is filter the particulates out of the indoor air. This is primarily done when the air is pushed through filter in a forced air HVAC system. However, even if an air filter is changed regularly, it may not be helping your home’s indoor air quality (IAQ).

Air Filter Issues That Reduce Indoor Air Quality

No Air Filter Present

You may thing this never happens, but it does. If you don’t have an air filter in place, it definitely isn’t going to filter any of the air that circulates in your home. This usually happens if the filter is removed because it’s hard to reach – like in a crawl space. Other times it may be taken out and then forgot to be put back in. Many things can happen if an air filter isn’t in place: reduced indoor air quality and potential damage to the HVAC equipment as it builds up with dirt, dust, and debris.

Filter Bypass

Bypass happens when a filter is installed incorrectly allowing air to pass right by the filter instead of through the filter. When this happens, air is not cleaned as nearly well as it should be. The type of filter doesn’t matter – bypass can happen any time a filter is improperly installed.

HVAC Runtime

Filters only clean indoor air when the system is running, pushing air through them. No filtering happens when an HVAC system is off. The mathematical equation for this is Filtration volume = Air flow x Runtime. Many times, homeowners may switch the fan to “on” instead of “auto” and this may work sometimes in certain areas, but higher energy bills are a result. Having the fan run constantly may also worsen indoor air quality by raising the humidity levels, especially in humid climates during the cooling season. Those in a dry climate, keeping the fan set to “on” can help.

Your best bet is to make sure you have the right sized HVAC system for your home to get as much filtering as possible. Also, minimize indoor air pollutants that need to be filtered out with source control, ventilation, and air sealing.

Inadequate Indoor Air Flow

As stated above, air flow and runtime go together. If returned ducts and filters are too small, the pressure in the system increases therefore reducing air flow. This can also happen if an air filter is dirty and not changed regularly resulting in high pressure and low air flow.

MERV Rating

Ranging from 1-16, MERV ratings score the performance level of a filter related to the removal of airborne particles from 0.3-10 microns in size. Microns are used as the measurement for airborne particles and a micron is 1/1000th mm…equal to 1/25,000ths of an inch. Logic would make it seem that you would want to buy a filter with the highest MERV rating possible, right? Oddly, that is not necessarily the case.

Air filters with high MERV ratings mean the filter is highly effective in preventing harmful airborne particles from circulating throughout your home. However, a high MERV rating filter could also be overly effective which, in turn, can prevent the air itself from being to circulate. This is a bad thing and the result may be poorer air quality in your home. Also, if the air is unable to circulate due to more resistance, your HVAC is doing more work than it should be. The result is an inefficient HVAC system, high energy bills, and it can even lead to costly repairs in the long run. Too low of a MERV rating doesn’t filter out enough particulates to keep your indoor air clean.

20x25x1 Home Air Filters

The 20x25x1 air filter is one of the most common sized air filters and can be found at most retail locations. A home’s air filter is quite often overlooked but maintaining it is, in fact, one of the most important steps you can take to keep your HVAC system efficient. Changing your 20x25x1 air filter has the following benefits:

  • Increased overall comfort
  • Improved indoor air quality (IAQ)
  • Increased lifespan of HVAC equipment
  • Decreased energy bills
  • Increased efficiency of cooling and heating

How does your 20x25x1 filter work?

20x25x1 Air Filters Clean Your Home’s Indoor Air

20x25x1 air filters

The EPA has done studies that show indoor air pollution as being one of the top 5 environmental health risks. Multiple sources decrease indoor air quality such as airborne particulates and matter getting indoors,  poor ventilation, increases in temperature and unbalanced levels of humidity. Other sources within your home also increase indoor air pollution. Fumes and smoke from cooking, the use of scented candles and air fresheners, cigarette/cigar smoke, carpet, drapes, furniture and even printers in the home contribute to indoor air pollution.

Improving Your Home’s IAQ

HVAC systems allow air to circulate through a home – air that is brought indoors from outside. During this circulation process, air is forced to pass through the air filter. The 20x25x1 filter traps the particles, dust and debris in the air, therefore pushing clean air back into your home. These particulates include:

  • VOCs (volatile organic compounds)
  • Hair
  • Pet dander
  • Dust
  • Dust mites
  • Vapors, odors, gasses
  • Organic waste
  • Carpet and fabric fibers
  • Smoke and emissions
  • Microbiological growth

Protecting your homes IAQ is possible by reducing the sources that are causing an increase in indoor air pollution. Reducing these sources results in the 20x25x1 air filter effectively capturing these pollutants and returning clean air back into the home. Air filters must be changed on a regular basis to ensure the cleanest indoor air possible.

Air Filters Protect HVAC Systems from Damage

Air filters not only protect indoor air quality, but they also protect your HVAC equipment from damage. Routine HVAC maintenance includes changing the air filters on a regular basis. Damage can happen to your AC system if dust and debris are allowed to build up on the motor and wires. If water collects around the evaporator coils/condensate lines mold can begin to flourish. Any holes and/or leaks within the equipment will allow debris to enter the system. Any of these can lead to very expensive repair costs or even permanent damage to the entire system. A clean 20x25x1 air filter saves you from damage to the following pricey components:

  • Thermostats
  • Flame sensors
  • Blower motors
  • Fire exchangers

20x25x1 Air Filters Improve Energy Efficiency

According to the Department of Energy, replacing dirty filters can reduce energy consumption up to 15%. Heating and cooling systems are responsible for nearly 1/2 your energy usage which means that there is a potential savings of 7.5% each month!

For example, in a home that has an energy bill of $100 per month and regularly replaces the air filters, there could be an energy savings of ~$7.50 monthly. Energy bills in the $200+ range will see even more energy savings – up to $30/month.

Other ways to improve indoor air quality:

  1. Housekeeping: Sweep, dust and vacuum floors and carpets, as well as blinds and vents regularly.
  2. Indoor air pollutant sources: Air quality is better in homes with hardwood floors and open windows than in homes with drapes and carpets. Any leaks and holes due to improper insulation will let unwanted pollution in if the home. Limit the sources of indoor air pollutants as much as possible so there is less stress on your 20x25x1 air filter and improve indoor air quality.
  3. Pets: Dander is the dead skin cells from an animal, much like human dandruff. Pets also track in all kinds of dirt, debris, pollen and dander from outside. If possible, keep animals out of bedrooms and off furniture. Wash blankets and floors on a regular basis to help keep the dander at minimum.
  4. Allergies: Seasonal allergies and/or asthma sufferers need indoor air clean to remain healthy and comfortable. Dust and other pollutants in the air irritates respiratory sensitivities.

What is the Best Air Filter for My Home?

Which Air Filter is the Best for Your Home?Typically, if you need of a new air filter you go to the nearest hardware store, grocery store or wholesale warehouse and pick a filter that fits into your HVAC system. Picking out a random air filter, however, may not save you money nor improve your home’s indoor air quality. Just like other purchases you make, there are many factors that go into selecting the right air filter for your home. The filter should perform efficiently and cost effectively.

Before making your selection, the first thing to understand are MERV ratings. MERV stands for Minimum Efficiently Reporting Value. It is a numerical value that rates the effectiveness of an air filter. MERV ratings are calculated by measuring the number of particles trapped in a filter compared to the total number the particles in the air trying to go through the filter. This means that if there are two filters in the same room, the filter that traps fewer particles will have a lower MERV rating.

MERV ratings aren’t the only factor involved in choosing the right filter for your AC unit. Selecting the filter with the highest MERV rating may lead to purchasing an air filter that potentially makes your HVAC system less efficient as it will block too much air flow. If this happens, the system is unable to heat or cool enough air to correctly maintain the temperature in your house. This means higher energy bills and the entire system could overheat.

The answer is BALANCE. The best choice is a filter that removes the most pollutants (MERV rating) and allows your HVAC system to perform efficiently. The following are the four different types of filters, their material makeup, their MERV rating and additional information that will help you make a decision.

Fiberglass Filters

Made from spun fiberglass and typically blue in color, these filters are one of the most popular types. They’re MERV rating is between 1 and 4 (low) and they trap 80% of particles 50 microns and larger/25% of particles between 3 and 10 microns. They do a great job of protecting your HVAC unit from large dust particles; however, they do not trap mold, pollen or other small particulates and are not recommended for people with allergies.

Pleated Air Filters

Comprised of folded sheets of cotton or a polyester-blend fabric, pleated filters are folded accordion style that allows for a larger fabric surface in a smaller area. The pleats make it easier for the air to pass through the filter making them more efficient. These air filters have a MERV rating between 5 and 8, trapping 80-95% of particles 5 microns and larger. If you find a cotton/polyester filter with lots of pleats and a MERV value of 6 or greater, this could be an ideal air filter solution. With these ratings, the filter removes a large number of pollutants AND keeps your HVAC system working at max efficiency.

Pleated air filters are also found with high MERV ratings from 11 to 13, trapping particles as small as 0.3 microns. At this efficiency level, they are approximately 2″-5″ thick and fit into box-like housings mounted onto the air handler.

Disposable Electrostatic Filters

Boasting a MERV rating of 10+, these filters are very effective at decontaminating indoor air. Electrostatic filters are composed of multiple layers of self-charging, polyester-blend fibers that create a static charge which attract particulates out of the air. They are framed by a polyester mesh that is positively charged. As air passes through the outer material, particulate matter becomes positively charged which is attracted to the negatively-charged inner material. Electrostatic filters are usually more expensive than fiberglass or pleated air filters.

Washable Electrostatic Filters

These filters are made of washable material, cased in aluminum mesh and framed in aluminum and MERV ratings of up to 10 or higher. For max efficiency, they need to be washed about every 3 months and their quality varies with cost. Higher quality washable electrostatic filters can last up to 8 years! There are some, however, that aren’t high efficiency and its difficult to determine the difference. After the filters are washed, they must be dried completely. Even the littlest bit of moisture left on a filter that is placed back in the air exchange can grow mold and bacteria that is recirculated back through your home.

All About 16x25x1 Air Filters

The 16x25x1 air filter is available at most retail stores as it is one of the more common air filter sizes. The importance of taking care of your home’s air filter is quite often overlooked, but keeping on top of it comes with many benefits, like:

  • Increasing overall comfort
  • Improving indoor air quality (IAQ)
  • Increasing your HVAC equipment’s lifespan
  • Decreasing energy bills
  • Increasing efficiency of heating and cooling

How does your 16x25x1 filter work?

16x25x1 Air Filters Clean Indoor Air

16x25x1 air filters

According to the EPA, one of the top five environmental health risks is indoor air pollution. Factors that cause a decline in indoor air quality include multiple sources that allow airborne particulates and matter to get indoors, poor ventilation, increase in temperatures and off-balance humidity levels. There are sources throughout your home that attribute to indoor air pollution. Smoke from cooking, air fresheners and candles, carpet, furniture, cigarette smoke and even printers contribute to indoor air pollution.

Can You Improve Your Indoor Air Quality?

Yes! HVAC systems allow air that is coming indoors to circulate throughout the home. It is during this circulation that air is forced to pass through the air filter. The 16x25x1 filter traps the particles and particulates in the air therefore passing clean air back into the home. These particles and pathogens include:

  • VOCs (volatile organic compounds)
  • Hair
  • Pet dander
  • Dust
  • Dust mites
  • Vapors, odors, gasses
  • Organic waste
  • Carpet and fabric fibers
  • Smoke and emissions
  • Microbiological growth

The main way to protect your homes IAQ is to reduce the sources that are contributing to indoor air pollution. As a result, the 16x25x1 air filter can effectively capture the pollutants and return clean air back into your home. Most importantly, your homes air filter needs to be changed regularly to ensure the cleanest indoor air possible.

Air Filters Protect Your HVAC System from Damage

Air filters not only protect indoor air quality, but also protect HVAC equipment from damage. Regular maintenance of a HVAC system includes changing dirty air filters with a new, clean one. The particles that cause indoor air pollution can also destroy your AC system. If dust and debris build up on the motor and wires, and water collecting around the evaporator coils/condensate lines lead to mold growth. Holes and/or leaks within the equipment also allow for debris to enter the system. Any of these factors can cause expensive repair costs and even permanent damage to the whole system. Using a clean 16x25x1 air filter saves you from damage to these pricey components:

  • Thermostats
  • Flame sensors
  • Blower motors
  • Fire exchangers

16x25x1 Air Filters Help Improve Energy Efficiency

According to the Department of Energy, replacing dirty filters with clean air filters can reduce energy consumption up to 15%. Combine that with the fact that heating and cooling systems are responsible for nearly half your energy usage, there is a potential savings of 7.5% each month.

For example, let’s say your home’s energy bill is $100/month. If you regularly replace your air filters, there could be an energy savings of ~$7.50 monthly! Energy bills in the $200, $300, $400 range are looking at even more savings – up to $30/month. Regularly maintaining your HVAC system with clean air filters is definitely worth it, but there are other ways it saves money as well.

Other factors to take into consideration to improve indoor air quality:

  1. Housekeeping: Regularly sweep, dust and vacuum floors and carpets, as well as blinds and vents. The circulating air from the AC blows particles around the house, worsening IAQ.
  2. Indoor air pollutant sources: Drapes and carpets in the home contribute to decreased air quality more than in homes with hardwood floors and open windows. Leaks and holes let unwanted pollution in if the home is not properly insulated. Limiting the sources of indoor air pollutants as much as possible will put less stress on your 16x25x1 air filter and improve indoor air quality.
  3. Pets: Like human dandruff, dander is an animal’s dead skin cells. Pets can track in all kinds of pollen, debris, and dander from outside as well. If possible, keep pets off furniture and out of bedrooms. Regular washing of blankets and floors will help keep the dander at minimum.
  4. Allergies: Seasonal allergies and/or asthma sufferers need indoor air clean to be comfortable and remain healthy and comfortable. Air filled with dust and other pollutants aggravates respiratory sensitivities.

Air Filter FAQs

air filter FAQsAll homes that has conditioned air running through the home’s HVAC duct work have air filters that need to be changed on a regular basis. They are not in plain sight, so they are often forgot about. However, they play an important role of cleaning the air before it is circulated through your home. Dust and other airborne particulates are removed from the air as it is forced to/from the cooling or heating mechanism and out through the vents. If the air filter becomes clogged, it can cause costly and irreparable damage to your HVAC system as it must work harder to cool or heat your home. No matter your living situation, a clean air filter is key to keeping your home comfortable and for the longevity of the components of your HVAC system.

Frequently Asked Questions About Air Filters

What Can Happen if I Don’t Change My Air Filter Regularly?

Air filters have a relatively simple function, but they can’t do their job effectively if they are not clean. Many different problems can arise from a dirty air filter, such as:

  • Dust and other airborne particulates build up on the mechanical components (i.e. fan blade and motor).
  • Allergens and dirt accumulate on the duct work walls.
  • Dirt can block or clog the HVAC coils.
  • The same coils can freeze due to lack of air flow.
  • The HVAC system cannot perform efficiently and increase your monthly energy bills.
  • A filter that doesn’t fit right allows dirt to bypass the filter.

How Do Air Filters Affect IAQ (Indoor Air Quality)?

Air filters primary job is to screen out any particles, even microscopic ones, from going through the HVAC system. Home-air pollutants can be particulate matter or even gas. There are many things that affect your home’s IAQ including:

  • Dust
  • Dust Mites
  • Spores
  • Mold
  • Viruses
  • Pollen
  • Pet Dander
  • Hair
  • Bug Parts
  • Lint
  • Ash
  • Pesticides
  • Tobacco, wood, or food smoke
  • Paint or other vapors
  • Cleaning product fumes

Do You Use the Same Filter For Heat and Air Conditioning?

Yes. The term HVAC stands for Heating, Ventilation, and Air Conditioning meaning it serves as a furnace and AC unit. The most common systems have hot and cold air that travels through the same ducts so they use the same filter, even though you may hear them called furnace filters or air conditioning filters. Filters can be found between the duct work and the mechanical components where the air travels in the air handler/exchange system.

How Often Should Air Filters be Changed?

The frequency in which an air filter should be changed depends upon your HVAC system and your preferences. The primary recommendation is to change the filter once a month when the system is being used regularly. It’s a good idea to pick a date each month and set a calendar reminder for yourself to change the filter. You can also check to see if the air filter needs to be changed by holding it up to a light source. If you can’t see through the filter, it’s time for a clean replacement.

Which Filter is Best for My Home and Family?

Selecting the right filter for your home and family takes a little self- assessment. Consider asking yourself the following questions to guide your decision. Any of the answers to them might affect which filter you decide to purchase – as well as how often you will change it.

  • How many people currently reside in the house?
  • Is the house cleaned on a regular basis (especially dusting and vacuuming)?
  • Are you in an area with open fields, roads, or other dusty areas?
  • Are there fur-babies in the house?
  • Does anyone in the house smoke?
  • Are you or other family members allergy sufferers?
  • How do you feel about the air quality in your home in general?

How Do I Change Air Filters?

It is just as important to correctly install your filter as it is to change it. It is easiest to change your filter if your unit isn’t active, if it is, turn it off. After locating the air filter housing, look at how it is sitting in the slot and make note of the direction the arrow is pointing. You may even want to consider marking the arrow direction on the frame of the housing with a permanent marker to make sure you always put it in the correct air-flow direction. Then, pull the old filter out, match up the arrows on the frame and the clean filter and slide the new air filter into the housing. That’s it!

What Size Filter Should I Get?

In addition to the directional arrow on the air filter, you will also see numbers denoting the filters width, length, and thickness. This is the air filter size your HVAC unit takes and should be the size you always order. Using the correct-sized filter is also important so your filter can do its job properly and not allow dirt and debris to bypass the filter. It should fit in the slot snugly, with no major gaps on the size and you should never have to force it into the housing.

Do Air Filters Help Me Save Money?

Yes, they do! The Department of Energy reports that replacing dirty filters with clean air filters can reduce your energy consumption up to 15%. When you combine that with the fact that your HVAC system is responsible for nearly half your energy usage, there is a potential savings of 7.5% each month. So, if your energy bill is $100/month, you could save $7.50 on each monthly bill just by changing your air filter! Is your energy bill in the $200, $300, $400 range? You’re looking at even more savings – upwards of $30 every month.

All About Your 16x20x1 Air Filter

The 16x20x1 air filter is one of the most common air filter sizes, and available at most retail locations. Homeowners don’t always take into account the importance of caring for their homes air filter, but doing so come with benefits, such as:

  • Increased comfort
  • Improved indoor air quality (IAQ)
  • HVAC equipment lifespan
  • Lower energy bills
  • Efficient heating and cooling

How does your 16x20x1 filter work?

16x20x1 Air Filters Clean Your Indoor Air

16x20x1 air filters

According to the EPA, indoor air pollution is among the top five environmental health risks. There are many factors that cause indoor air quality to decline including multiple sources allowing airborne particulates and matter to enter the home, poor ventilation, increased temperatures and unbalanced humidity levels. On top of these, there are sources that attribute to indoor air pollution throughout your home which you may not even consider pollutants. Things such as air fresheners and candles, furniture, carpet, smoke, cooking and even printers.

How Can You Improve Your IAQ?

The good news is that your home’s HVAC system allows the air coming indoors to circulation throughout the home. During this cycle, the air is forced to pass through an air filter. The 16x20x1 filter traps airborne particles in the air, therefore passing cleaned air back out into your home. These pathogens include:

  • VOCs (volatile organic compounds)
  • Hair and pet dander
  • Dust and dust mites
  • Odors, vapors and gasses
  • Organic waste
  • Carpet and textile fibers
  • Smoke and emissions
  • Microbiological growth

The first step to protect your homes indoor air quality is to reduce the sources that contribute to indoor air pollution. Then, the 16x20x1 air filter is able to better capture the pollutants, returning clean air back into your home. This is also why it is so important to change your air filter regularly so you have the cleanest indoor air possible.

Air Filters Protect Your HVAC System from Damage

In addition to protecting indoor air quality, they also protect your HVAC equipment. Regular care and maintenance of your HVAC system includes changing dirty, clogged air filters out with a clean, fresh one. The same particles that pollute your air can also destroy your AC system. Dust and debris can build up on the motor and wires and water collection on the evaporator coils and condensate lines can cause mold growth. If there are any holes or leaks within the equipment, this also allows for more debris to enter the system.  When this happens, you can be looking at expensive repair costs and even permanent damage to the entire system. Using a clean 16x20x1 air filter saves you from these pricey repairs:

  • Thermostats
  • Flame sensors
  • Blower motors
  • Fire exchangers

16x20x1 Air Filters Help Improve Energy Efficiency

The Department of Energy reports that replacing dirty filters with clean air filters can reduce your energy consumption up to 15%. When you take that and combine it with the fact that your heating and cooling system is responsible for nearly half your energy usage, you could potential save 7.5% each month.

This means that if your energy bill is $100/month, you could save $7.50 on each monthly bill just by changing your air filter! Is your energy bill in the $200, $300, $400 range? You’re looking at even more savings – upwards of $30 every month. So, is it worth regularly maintaining your HVAC system with clean air filters? In this scenario, yes, but there are ways it saves you money as well.

In addition to following the manufacturers recommendation for how often to change your 16x20x1 air filter, there are other factors to take into consideration in regards to your homes indoor air quality:

  1. Housekeeping habits: Dust, vacuum and sweep regularly. Not only your floors and carpets, but also your blinds and vents as well. The moving air from your central air system blows particles around your house, making IAQ worse and more noticeable.
  2. Sources of indoor air pollutants:  A home furnished with drapes and carpet contributes to decreased air quality than a home with hardwood floors and open windows. Insulation is also important as leaks and holes let unwanted pollution in. To improve indoor air quality and put less stress on your 16x20x1 air filter, limit the sources of indoor pollutants as much as possible.
  3. Pets: Pet dander is the animal’s dead skin cells, similar to human dandruff.  Our furry friends also track in all kinds of debris, dander and pollen from outside. Try to keep your pets off the furniture and out of the bedrooms if at all possible. Wash blankets and floors regularly to keep the dander at bay.
  4. Allergies: People who have seasonal allergies and/or asthma need their indoor air clean to remain healthy and comfortable. Air filled with dust and other pollutants aggravates respiratory sensitives

The Importance of MERV Ratings

How Air Filters Work and MERV RatingsWhile we are still in the midst of the Covid-19 pandemic, it seemed to be a good time to revisit the importance of MERV ratings when it comes to the filtration in your home. MERV stands for Minimum Efficiency Reporting Value. The ASHRAE (the American Society of Heating, Refrigeration, and Air Conditioning) developed the MERV system in 1987 as a scale used to measure the effectiveness of air filters. The MERV ratings system makes it easier for consumers to compare the effectiveness of all the different air filters available.  The material used, quality and construction of air filters may differ; however, the MERV system sets expectations for the level of filtration provided from an air filter with a specific MERV rating. In simpler terms, this means that any MERV 8 rated air filter will have the same level of filtration another filter with a MERV 8 rating, no matter the material, quality, or construction.

Ranging from 1-16, MERV ratings score the performance level of a filter related to the removal of airborne particles from 0.3-10 microns in size. Microns are used as the measurement for airborne particles and a micron is 1/1000th mm…equal to 1/25,000ths of an inch. The human eye can see particles beginning around 20 microns but in the right conditions, it is sometimes possible to see particles as small as 10 microns. To put that into perspective, a dot (.) is just about 600 microns.

Comparing MERV Ratings

The table below shows a low-level comparison of MERV ratings. Check out our MERV Rating Comparison chart for a more in depth look at the differences.

System Protection Level Dust Control Level Allergy Concern Level
MERV 8 Good Good Mild
MERV 11 Better Better Moderate
MERV 13 Best Best Severe

MERV Ratings and COVID-19

What filter is best to protect your home from COVID-19?  The National Air Filtration Association reports that there is no straight forward answer to this question due to all the unknowns regarding the nature of SARS-CoV-19 containing particles and droplets.  What is known is that low-efficiency filters (less than MERV 8) are highly unlikely to make a difference.  Properly installed higher efficiency filters can remove particles of a relevant size depending on their installed capture efficiency, but current information does not allow for specific recommendations.

Buying Filters with High MERV Ratings

Logic would make it seem that you would want to buy a filter with the highest MERV rating possible, right? Oddly, that is not necessarily the case.

You now know that air filters with high MERV ratings means the filter is highly effective in preventing harmful airborne particles from circulating throughout your home. However, a high MERV rating filter could also be overly effective which, in turn, can prevent the air itself from being to circulate. This is a bad thing and the result may be poorer air quality in your home. Also, if the air is unable to circulate due to more resistance, your HVAC is doing more work than it should be. The result is an inefficient HVAC system, high energy bills, and it can even lead to costly repairs in the long run.

What MERV Rating Should I Buy?

This really all depends upon your individual HVAC system, but for a typical home the ideal MERV rating would be between 8 and 13. As far as protection from the coronavirus, you’d definitely want stay away from MERV ratings under 8. The most important thing when choosing an air filter, regardless of MERV rating, is that is compatible with your HVAC system. You may think that selecting high MERV rating filters will remove more of the harmful particles from your home, but too high of a MERV rating could actually reduce the air quality of the air you breathe in your home. Filters with higher MERV ratings also must be changed more frequently than those with a lower MERV rating.

Filters with MERV ratings higher than 16 are available, however, they are thicker and denser, and your typical residential HVAC system cannot readily handle them. And, as stated before, they can actually interfere with the airflow by restricting it. This in turn can reduce the effectiveness of your heating and cooling systems and can even result in damage to the HVAC equipment. You should consult with an HVAC professional to make sure that your HVAC system can handle filters with MERV ratings higher than 16 before buying and installing one.

If you still want the filtration of a MERV 16 but your HVAC system can’t handle it, there are additional units that can be installed along with your HVAC system that are designed for air filtration and purification. These air cleaners can provide an additional step “on top” of the regular filtering, thus cleaning your air even further.

Sick Building Syndrome and IAQ

Sick Building Syndrome and Indoor Air QualityThe term “Sick Building Syndrome” is not readily known. Just by the name alone, you can imagine it has something to do with being in an unhealthy indoor environment. Sick Building Syndrome, or SBS, is a medical condition where people in a building suffer from symptoms of illness or feel unwell for no apparent reason. Spending a lot of time in the unhealthy environment result in symptoms such as tight chest, wheezing, sore throat, eye, and nose irritation and in some sever cases, dizziness, and nausea. But what makes a building ‘sick’? The causes of SBS are usually linked to flaws in the heating, ventilation, and air conditioning (HVAC) systems.

Factors That Contribute to Sick Building Syndrome

Inadequate Ventilation

Ventilation, the amount of fresh air that is brought indoors, is extremely important. Shockingly, a NIOSH (National Institute for Occupational Safety and Health) research study concluded that over fifty percent (52%) of SBS cases could be traced back to inadequate ventilation. When HVAC systems were first installed in buildings, building ventilation standards called for around 15 cubic feet per minute (cfm) of outside air for each building occupant. The oil crisis of the early 1970s further reduced the ventilation standards to only 5 cfm to save energy. And it did just that. However, building occupants health began to decline and people started getting sick in droves. Thankfully, 20+ years later, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) developed a ventilation standard that balanced adequate ventilation and energy efficiency to prevent sickness. Now the requirement is back to a minimum of 15 cfm of outdoor air per person and 20 cfm per person in office spaces.

Carbon Dioxide

When CO2 levels are high (> 800 to 1000 parts per million) room air begins to feel ‘stuffy’. However, SBS symptoms can occur at a much lower concentration and anything above 1000 ppm can cause people to become quite sick. Thankfully, this level is very uncommon due to the proper ventilation system requirements in place as described above.

Chemical Contaminants from Indoor Sources

The amount of chemicals that make up the structure of our indoor spaces is quite overwhelming. Carpet, upholstery, paint, adhesives, copy machines, cleaning agents, etc. are all a part of our everyday lives, bringing an abundance of unhealthy chemicals into the air we breathe. These toxins include volatile organic compounds (VOCs), e.g. formaldehyde, which cause chronic and acute health effects at high levels.

Outdoor Contaminants

The outdoor air that enters a building is also a factor in indoor air pollution. Although adequate ventilation is a requirement, the type of air that comes inside is just as important. Think about all the exhaust fumes toll road workers are exposed to. Or the drive-through operator at a fast food restaurant who has the window open while idling cars wait for their order. Outdoor contaminants can also get into a building if the air intake vents are poorly located and polluted air and not fresh air is sucked into the building.

Natural Toxins

Mold, bacteria, viruses and pollen are all examples of natural toxins that can grow if your HVAC system is not properly maintained. Mold will grow in any standing pools of water near an HVAC unit, especially as outdoor temperatures increase. Water damage inside the building’s carpet, ceiling tiles or insulation can also be a cause of mold growth if not properly taken care of. Plants and weeds growing around the HVAC unit also cause issues as air flow into the building is restricted, pulling more pollen and allergens into the indoor air.

How Can We Prevent Sick Building Syndrome?

The most beneficial thing that can be done to reduce the effects of poor indoor air quality is to improve air filtration. Air filtration provides us with a means to attain the desired level of indoor air quality. Air filters were originally intended to simply shield the components of your expensive HVAC system, protecting it from harmful dust build-up and extending its life. As the manufacturing process of air filters evolved, filtration media became more refined and specialized. This allowed air filtration to go beyond system protection into cleaning contaminants, allergens, and other bothersome particles from our air using high-efficiency pleated air filters. Since then there has been a significant improvement in indoor comfort and cleaner air in our homes and businesses.

Standard Stock Size Air Filters

Facts About Standard Sized Air FiltersHave you heard the term “Standard stock size” air filter? This merely means that your HVAC unit has a filter that is a common size that is mass produced and easily found. For example: 16x20x1, 20x20x1, 16x25x1, 20x20x1 are all standard sized air filters. Every unit has a specific sized filter which allows the it to perform correctly and efficiently. Most AC and HVAC units use standard sized filters, but some do require a custom size air filter to be purchased and installed. But why is filter size important? According to EPA.gov, incorrectly sized or installed filter frames can cause air seepage, which significantly decreases filter effectiveness. Also, if there is any air flow resistance caused by using a filter that is not correctly sized, it can result in unnecessary stress on the HVAC unit itself, potentially damaging your system equipment and increasing your energy bills.

Standard Size Air Filter Facts

  1. There are only about 10 of the most common air filter sizes available at retail locations. US Home Filter makes over 80 standard stock sizes that local stores do not have the shelf space for, nor the inventory capacity to keep them in stock. We do manufacture and stock them all because that’s our business! So take a look at our stock filters, from the most common 16x20x1, 20x20x1, 16x25x1, 20x25x1 to other sizes like 8x16x1 to 30x36x2 to 25x29x4 to 20x25x6. If we don’t have it, we can make it!
  2. Nominal Size: This is the approximate size, such as 16x25x1. All 16x25x1 filters are designed to fit standard 16x25x1 filter slots.
  3. Exact Size: This can vary slightly depending on the manufacturer. The die-cuts (filter frames) are manufactured in bulk and purchased as a raw material for making air filters and determine the exact size of the air filters. The exact size is always slightly smaller than the nominal size to allow the filter to properly fit in the slot or housing. For example, a stock size of 20x20x1 may have exact dimensions of 19-1/2 x 19-1/2 x 3/4. This is completely normal and is the standard in air filter manufacturing.
  4. Slight variances in size may make a difference in certain situations. For instance, you may find that the stock size at your local hardware store is just a bit too big to fit your housing slot; however, you may be able to find the same stock size online by a different manufacturer that is slightly smaller size and it fits perfectly.
  5. There are thousands upon thousands of possible exact air filter sizes that can be used in an HVAC unit. Because of this, you will not always be able to find a filter at a store or online as you are able to find regular stock sizes. If this is your situation, you will need to order a custom size air filter. Custom filters are not made to a nominal size, with a smaller actual size as stock sizes are made. At US Home Filter, we make your custom size filter according to your HVAC manufacturers specifications.

Finding the Right Fit

The filters don’t need to fit with an “airtight” seal, but you should be able to easily install and uninstall your filter without a struggle. Your filter should be a bit smaller on each side of the filter housing slot, allowing you to slide the filter in and out with ease. For most systems you can use a standard sized filter within 5/8 of an inch smaller than the air filter housing.

US Home Filter is Here for YOU
