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.

How to Properly Insert a New HVAC Filter

arrow on air filter for air flowChanging your home air filters seems to be an easy task; however, it’s one that is easily forgotten. Clean air filters matter. It is extremely important to regularly monitor and change them according to the manufacturer’s directions. When air filters become clogged with dust, dirt and debris, they are no longer able to their job of improving the indoor air you breathe. Dirty air filters also force your HVAC system to work harder than necessary, decreasing equipment’s life and increasing your energy bills. In fact, Energy.gov reports that replacing a dirty, clogged air filter with a clean one can lower your central air conditioner or furnace energy consumption between 5 and 15 percent! So, you go to change your air filter, but you end up a little confused. Not really paying attention to small details, you take the old filter out, grab the new filter, but which way does it go in? There’s an arrow on the filter with the words “Air Flow”, but what does that mean? How do you know which way the air flow is going? Here’s what you need to know to properly insert a new filter into your HVAC system.

The Arrow and Air Flow Direction

To properly insert a new filter, look for the arrow! The arrow on your filter should always face the unit and away from the return air duct that carries the air that will be heated or cooled. HVAC systems push the cool or warm air out and pull spent air in, recirculating the air throughout your home. This means you want the spent air that is being pulled in to flow through your air filter before being pushed back out into your home. Still confused? A simpler way to figure this out is to always make the arrows face the ceiling or wall. If your filter is on the wall, the arrow should face the wall. If your filter is on the ceiling, the arrow should face the ceiling.

If you find yourself with an air filter that doesn’t have an arrow on it, check it again, as nearly all filters have it. Still not finding the arrow? In this case you’ll need to look at each side of the filter. The side with the wire frame should be facing outward and the side without it will be inside closer to the unit.

Pro Tip: Once you’ve got it figured out, draw the airflow direction arrow on the HVAC housing or ductwork with a permanent marker. The next time you change your filter, match up the arrows’ directions and viola, you’ve properly changed your air filter.

Benefits Of Home Air Filters

How Air Filters Work and their benefitsThe list of benefits that come from the use of home air filters can be outlined easily; however, the list contains three very valuable benefits. You may not think about it often but having a full understanding of the true advantages of these relatively simply items will make you realize their importance. Air filters come in a vast number of sizes and several MERV ratings. No matter the size difference or the types available, all air filters are designed to fill these main purposes. The filter size you need is determined by the HVAC unit installed in your home, but there is flexibility in selecting the MERV rating that is best for you regarding desired level of dust control and reduction in allergens. So, what are these three top benefits of home air filters?

Top 3 Home Air Filter Benefits

#1 HVAC System Protection

The lack of maintenance is the most common reason for HVAC system malfunction or failure. Dust is often the culprit as it can build up on the integral parts of the unit. Once the dust has accumulated to a high enough level, there will inevitably be problems. These problems; however, can almost always be prevented by regular maintenance. One of the simplest ways to maintain your system and preserve its life is to use an air filter that fits properly and change your air filter regularly. By doing so, a proper rate of airflow will be circulated around your home so it can be heated or cooled to your desired temperature. This also provides your HVAC system with a protective barrier against dirt and debris; the original and primary reason for home air filter use. Air filters, although inexpensive in comparison to the cost of your HVAC unit, carry a high level of responsibility in keeping your system running efficiently and smoothly. Your air filter traps dust and dirt particles before they can reach and accumulate on the internal and moving components of the unit. The following parts can be contaminated with dust build-up when a poorly-fitting, low quality, or dirty filter is used:

  • fan blade
  • motor
  • coil
  • duct work and vents

#2 Reduction of Dust in Your Home

Your air filter works hard to minimize the dust levels in the indoor air you breathe by preventing dust and debris from collecting on the mechanical parts of your heating and air conditioning system. High-efficiency pleated filters provide a large surface area and a considerable amount of dust-holding capacity. Pleated filters trap and hold several grams of dust, preventing it from blowing through your duct work back into the air you breath and inevitably settling on the surfaces in your home. Battling dust that continues to reappear on bookshelves, tables, window treatments, and decor is a constant point of frustration. Although virtually impossible to eliminate, dust can be greatly reduced by your home’s air filter, assisting you in the fight against dust in your home. US Home Filter recommends a MERV 8 rating at the minimum on your home air filter to control average levels of dust. If you need greater protection from smaller dust particles (fine, suspended dust), then you would benefit from a higher MERV rating. As the MERV rating increasing, finer particles are captured and a higher percentage of dust and microscopic particulate matter (PM) is removed. It is this subject of filtering fine particles, even as small as attached bacteria and viruses, that leads us into the next benefit, a recently popular topic of discussion.

#3 IAQ Improvement

While system protection is the priority and dust reduction is a close runner-up, the importance of air filters related to our indoor air quality (IAQ) is the third on the list of benefits of home air filters. This has become increasingly important as the average person spends 90% of their time in indoor spaces where concentrations of pollutants are 2-5 times greater as compared to the outdoor levels. Wouldn’t you want the cleanest air in the areas where you spend the greatest amount of time? IAQ may be the most important factor in air filtration for those that have serious concerns such as severe allergies and sensitivities to certain particulates and contaminants, perhaps just as important as other items they use, such as allergy medication, to lessen the symptoms caused by allergens. A MERV 8 rating is enough for those that have mild allergies and sensitivities. We recommend a MERV 11 rated air filter when you experience a moderate level of allergy issues. If you are highly sensitive to particulates, pollution, contaminants and various allergenic elements, you should consider a MERV 13 filter which will scrub your air from the finest particles, keeping your air as clean as fresh as possible.

Improving Indoor Air Quality in Winter

energy saving in winter indoor air qualityHomes are built to be energy efficient, keeping the heat out in summer and keeping heat in during winter. When winter approaches, homeowners prepare by tightly sealing cracks and windows that could allow cold air into their home. This results in reduced ventilation due to the improved air sealing and insulation. It also prevents any fresh air from entering the home, increasing the concentrations of pollutants and allergens in the home. Add in the fact that more time is spent indoors (hobbies and projects come inside), the increased use of scented candles and cleaning products, and your home’s indoor air quality (IAQ) is greatly reduced. Trapping air inside your home leads to unhealthy conditions, which is why ventilation and other systems are so important to refresh indoor air and improve your home’s winter indoor air quality.

5 Tips for Improving Winter Indoor Air Quality

According to the EPA, the air that we breathe in our homes, schools and offices can put us at risk for health problems. By improving your winter indoor air quality, you are working to reduce allergens such as mold spores, pollen, dust, pet dander and other impurities. So, what can you do to improve the indoor air quality in your home? Here are 5 tips that will keep you and your family comfortable and breathing a bit easier this winter.

Circulation: Circulation is a form of air replacement and is surprisingly beneficial during the winter months when you tend to keep your home sealed up. On a warmer winter day, allow some clean fresh air to enter and circulate throughout your home. This refreshes your indoor air quality, allowing the “trapped” allergens inside your home a chance to move outside.

Humidity: Adding humidity to the air is often the norm during the cold, dry months by use of humidifiers. However, many allergens, such as dust mites, mold, and bacteria thrive in overly humid conditions. It is important to keep the humidity level in your home in check, ideally around 35%-50%. If the humidity is too low, viruses maintain their infectious nature, too high and allergens multiply. Replace your humidifier filters with fresh humidifier pads or filters twice per season. Use bathroom exhaust fans to keep the moisture level down and keep an eye on basements and storage areas as well. These are ideal locations for potential moisture.

Smoke: Smoke from tobacco, fireplaces, cooking and even candles affects your winter indoor air quality (IAQ). Many of us love the scent of our favorite candle or sitting in front of the fireplace on a cold night, especially during the holidays, but they do not improve the quality of the air you breathe. This does not mean you shouldn’t enjoy these things during those snowy days and nights, but that it is something to be aware of as smoke particles can be bothersome to anyone who suffers from respiratory conditions.

Air Filtration: Furnace filters are a huge help to improving winter indoor air quality beyond their basic purpose of just protecting your HVAC system. Filters add another level of defense by cleansing your air of impurities. Change your air filters regularly to allow your system to work optimally AND provide a new surface area to trap and collect dust and allergens.

Regular Cleaning: Maintaining a clean home will help keep the level of contaminants and dust in your home to a minimum. Once dust and allergens have settled, it is more difficult for them to be trapped by your furnace filter. When you clean, the area where the dust has settled is disturbed, re-dispersing the dust into the air, allowing for another opportunity to be captured. Unfortunately, dust always settles again and keeping it at bay is an ongoing battle. Regular cleaning of surfaces, dusting and vacuuming is the way to help tackle these issues and improve your IAQ!

Winter Energy Saving Tips

save energy and winter indoor air qualityFor many, winter is the most wonderful time of the year. It is a season filled with holiday cheer, gatherings with friends and family and holiday magic that only happens when the temperature drops. This is also the time of year when your energy bill tends to climb as the air cools and need to keep yourself and your loved ones warm and cozy indoors. The good news is, there are things you can do to limit the increase on your energy bill and stay comfortable inside. Here are a few effective tips to save energy this winter season that will hopefully make the cold a little more bearable.

Tips to Save Energy in the Winter

Open curtains and blinds during the day – Keeping your blinds and curtains open during the day, especially those on windows that let the most sunlight in, allows the sun to naturally warm your home. In turn, your heating unit won’t need to kick on as often as it would have to if the curtains were drawn. To continue to save energy after the sun goes down, make sure to close the curtains and blinds to help insulate the windows and keep the heat in.

Insulate windows – Unless you have heavy insulating drapes that fit tightly on your window, closing curtains is not the most effective way to keep the cold air out. A more popular, cost effective method is to install clear plastic film around the window frame, creating an airtight seal. The film can be attached directly to the frame or onto the wall. After attaching, simply use a hair dryer to shrink the plastic to seal out the cold air that can seep in through your windows.

Check the fireplace – Traditional fireplaces create a warm, inviting atmosphere we all enjoy, but they need to be properly maintained to save energy in your home. The chimney and fireplace should be inspected once a year, kept clean and sealed. Many people don’t realize that while fireplaces may warm you in the room you’re in, they also suck the heat out of home making it feel colder in other parts of the house. When not in use, close the flue but only AFTER the fire is completely out and there are no smoldering ashes. Closing the flue too soon after the fire is out can lead to carbon monoxide poisoning. If you want your fireplace to actually heat your home, call a professional to have it fitted with glass doors and an exchange system that pushes warm air into the home and pulls cold air into the fireplace.

Add insulation – Adding additional insulation to the external walls, basement and attic increases the heat retention in your home. You can install it yourself or hire a professional. A additional layer or two of insulation can save you a lot on your heating bills over the life of your home.

Lower the thermostat – It’s a simple thing to do, but very cost effective. You will save around 2% on your heating bill for every degree you lower your thermostat! According to the Department of Energy, you can easily save energy in the winter by setting your thermostat to 68°F while you’re awake and setting it lower while you’re asleep or away from home. They recommend turning your thermostat back 7°-10° for 8 hours a day to see the largest energy savings.

Install a programmable thermostat – Programmable thermostats help manage energy usage when the heating system is needed most, plus they take the guess work and human error out of the mix. Always make sure that your thermostat has a fresh set of batteries. As stated above, for the most energy savings, set your thermostat at a lower temperature when you are sleeping or not at home.

Check your heating vents – Take a walk through your home to check that all vents are unblocked and have space to push warm air out. It’s inevitable that over time, furniture and toys may shift or be placed in areas that block vents. If the warm air is being blocked from getting out, your HVAC system will have to work harder to get your home to the temperature set on your thermostat.

Clean and maintain the heating system – An annual cleaning and inspection of your HVAC system can do wonders for the unit’s performance when it’s working hard to heat your home. A dirty system causes your unit to work harder, costing you more money, and can also lead to equipment failure. Continue to change your air filters monthly, or according to the manufacturer’s directions. The Department of Energy also reports that replacing dirty filters with clean air filters can reduce your energy consumption up to 15%. With your heating and cooling system being responsible for nearly half of your energy usage, you’re looking at a potential savings on your energy bill of around 7.5% every month.

Protecting Your Home from the Flu

preventing home fever and fluFlu season is here and avoiding the flu virus can be tricky. In addition to getting a yearly flu vaccine, health officials urge everyone to wash their hands regularly as it may be the best way to stop the virus from spreading. The CDC also recommends the following everyday actions to prevent the spread of germs:

  • Avoid close contact with sick people if possible
  • While sick, limit contact with others
  • If you have flu symptoms, do not go back to work or school for at least 24 hours AFTER your fever is gone
  • Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
  • Wash your hands often with soap and water. If soap and water are not available, use an alcohol-based hand rub.
  • Avoid touching your eyes, nose and mouth. Germs spread this way.
  • Clean and disinfect surfaces and objects that may be contaminated with germs like the flu.

Your home (and office) has multiple surfaces that are popular areas for viruses and germs to land. Children’s toys, doorknobs, sinks and telephones are all areas to clean and disinfect regularly. The germiest thing in the home, though, is the remote control. The flu virus spreads though touching something a sick person has touched or sneezed on. The remote control is touched by everyone in your house at some point, especially when sick. Disinfect your remote controls! Unfortunately, you may still find yourself exposed to the flu virus be it by co-workers or school-aged children. The good news is that there are further steps you can take to protect your home from the virus taking root in your house.

Tips to Flu-Proof Your Home

Humidify Your Home

A 2013 study found that the ability of airborne viruses that cause flu infections was greatly reduced when humidity levels were increased to 43% or above. In fact, low humidity environments resulted in 70-77% of viruses retaining their infectious nature, and that number dropped to only 14% when the humidity was increased to 43% or more. A 2009 study resulted in the same conclusion: humidity limits the transmission of the influenza virus. The fact is bacteria and viruses are not able to travel well in moist air. Adding a humidifier to your home could be the difference between remaining healthy this winter or getting the flu.

However, even with all the humidifier benefits, they can become a source of bacteria and mold if they aren’t cleaned regularly. To make sure the humidifier is working for you and not against you, be sure to:

  • Use demineralized or distilled water. Minerals found in tap water can build up in your humidifier and increase growth of bacteria.
  • Clean once a week. The longer you wait between cleanings, the harder it will be and there’s a higher risk of mold and bacteria build up.
  • Change filters regularly! Not all humidifiers have filters, but if yours does, change it following the manufacturer’s directions. US Home Filter has a FULL selection of humidifier pads!
  • Keep humidity levels ideal. Too much humidity can be just as problematic as not enough humidity. You can measure the humidity in your home with a hygrometer, available at home improvement and electronic stores. The ideal humidity range for your home is between 40-50%.

Ultraviolet Air Cleansing

Another option to protect your home from the flu virus and other germs is to add a UV light air purification to your home. A UV light air purification system usually combines a traditional filter with a UV lamp. A traditional HVAC or furnace filter’s main purpose is to trap dust and other particles from the air, not allowing them back into the air you breathe. When you combine a traditional with a UV lamp, both the removal of particulate matter from the air and the killing of germs and bacteria is maximized.

UV light air purification is by no means a replacement for the regular disinfection in a home or office. However, when used in conjunction with traditional cleaning methods, UV light air purification enhances any system in place that reduces the spread of diseases.

Air Cleaners and Filter Publications

Energy Efficiency and Indoor Air Quality and Air CleanersIt is a proven fact that the most effective way to improve indoor air quality is by removing the sources of pollutants and ventilate with clean air from outside. Filtration, in conjunction with ventilation, is the best way to control these indoor air pollutants. The two main ways of doing this is by using a portable air cleaner and/or changing the air filter in your furnace or HVAC unit.  Portable air cleaners, also called air sanitizers or air purifiers, filter the air in one single room or small area. HVAC or central furnace filters filter air throughout your home. While HVAC filters and portable air cleaners can greatly reduce indoor air pollution, they are not able to remove all pollutants from the air you breathe.

The best way to protect your family from indoor air pollution is to understand filtration and how it works. That way you can make an education decision on what filter is best for your home. Did you know the EPA provides downloadable resources regarding home air cleaners and HVAC/furnace filters?

Portable Air Cleaners, HVAC and Furnace Filter Publications

Guide to Air Cleaners in the Home

This guide focuses on indoor pollutants and the importance of clean air in the home. It is specifically for consumers and includes information on the difference between and how to select portable air cleaners, HVAC and furnace filters. It explains that portable air cleaners, also known as air sanitizers or air purifiers, are designed for single room filtration while central furnace and HVAC filters are designed for whole home filtration. The guide also has an extensive common questions and answers section on air cleaning and filtration.

Residential Air Cleaners – A Technical Summary

This publication comes from the EPA, Office of Radiation and Indoor Air, Indoor Environments Division. Like the Guide to Air Cleaners in the Home, it also focuses on residential air cleaners, not those that are used in commercial or industrial settings. The document provides a much more in depth look at the types of indoor pollutants, the different air-cleaning technologies and devices available, metrics to compare them and their effectiveness in removing pollutants indoors. There is also study results on the effects air cleaners can have on your health.

New Guidance for Residential Air Cleaners

Written by members of the ASHRAE (The American Society of Heating, Refrigerating and Air-Conditioning Engineers), this guide is mainly for professionals, but is also a resource for non-professionals who want to learn more about residential indoor air quality (IAQ). Like the publication above, it is a much more in-depth look at the effective ways to clean indoor air, what steps to take if those ways are not possible or don’t work, as well as information on portable air cleaners and central HVAC systems.

Understanding Air Filters and How to Choose the Right One

How Your Air Filter Work and How to Choose the Right OneThe air filter in your home HVAC unit is a critical component of the whole system. Made from mostly cardboard and fiber, they may not seem elaborate, but air filters greatly affect your unit’s performance. Not only do they play a big role in indoor comfort, but they also have a major impact on HVAC equipment. Here is what you need to know about air filters, how they work, and why they are so important in maintaining your home’s heating and cooling systems. Hopefully, it will also aid you in selecting the right filter to best fit your needs!

How Air Filters Function and Work

Air filters are typically manufactured with one of these two materials: spun fiberglass material or pleated paper/cloth. The material is enclosed in a cardboard frame, then made into different sizes to fit all the various HVAC systems available. The filter’s primary function is to trap and hold all different kinds of particulates and contaminants in the air that circulate through your heating and cooling system. Most of which affect your health and comfort. A few of these contaminants include:

  • Mold & spores
  • Pollen
  • Hair & animal fur
  • Bacteria/Microorganisms
  • Dust and dirt
  • Fibers and lint
  • Metal, plaster or wood particles

The air filtration occurs when the disbursed air is “sucked” back into the HVAC system where it is conditioned and then used again. During this process, air is forced through the air filter. The spun fiberglass or pleated paper/cloth traps the particulates and contaminants, removing them from the air. These particles are now no longer able to be recirculated into the air you breathe.

MERV Ratings and Filter Efficiency

As with almost all products we purchase, there are lower-end, mid-level and high-end choices available. Not all products are created equal. Not all air filters will clean your air with the same efficiency. The higher the quality, the more contaminants that will be removed from your indoor air. Keep in mind that these higher quality air filters are usually cost a bit more.

This is where the filter’s MERV rating comes into the picture. MERV stands for “Minimum Efficiency Reporting Value”. It is a numeric value for rating and comparing the filter’s efficiency and performance. The range for standard MERV values is typically from 1 to 16; the number indicating how well the filter will remove material from the air. The higher the MERV rating, the better the filtration.

MERV 1-4: Common standard filters. Basic filtration. Low cost.
MERV 6-8: Good filtration and typically used in residential settings. Made of cloth or pleated paper.
MERV 9-12: Middle of the road filters with relatively high efficiency. Can trap particles of 1 micron or larger.
MERV 13-16: Highest efficiency, best standard filters available. Can trap particles as small as 0.3 microns or larger.

There are filters available with MERV ratings higher than 16; however, they are thick and dense, and a typical residential HVAC system cannot readily handle them. In fact, they can interfere with the airflow by restricting it. This reduces the effectiveness of your heating and cooling systems and can even result in damage to the HVAC equipment. Make sure that your HVAC system can handle filters with MERV ratings higher than 16 before buying and installing one.

There are also additional units that can be installed along with your HVAC system that are designed for air filtration and purification. These air cleaners provide an additional step “on top” of the regular filtration, cleaning your air even further.

Air Filter Maintenance

All the air that circulates through your HVAC system, to heat or cool your home, will eventually pass through the air filter. Therefore, it is extremely important to keep your air filters clean and change them regularly. Dirty, clogged air filters can:

  • Cause HVAC system malfunctions and equipment damage.
  • Reduce airflow inside the HVAC system, making the fans work harder and wear out quicker.
  • NOT remove particulates and contaminants as effectively as they should, therefore releasing these back into your indoor air (the air that you and your family breathe).
  • Cause contaminates to build up in your duct work.
  • Cause the HVAC equipment to work harder, increasing your home’s energy usage and your monthly electric bill payments.

Air filters should be checked at least once a month. If they are dirty, change them out with a fresh clean air filter. To check if your air filter is dirty, remove it from the air filter and hold it up to a light source. If you can’t see the light through the filter, then it’s time for it to be changed.

Fighting Fall Allergies

allergiesThe fall season is here. Summer blooms have come to pass and made way for autumn shades, cool evenings, and more time spent indoors. Although fall is a favorite time of year for most people with its vibrantly colored foliage, milder temperatures, and delicious comfort foods, many live in fear of the itchy, watery eyes, sneezing and runny nose this season brings them. That means the “fight against fall allergies” that afflicts numerous individuals is in full force.

In addition to the beautiful elements that many look forward to, the autumn weather also welcomes in a new season of allergies for others that can be particularly bothersome. Some allergy sufferers will find relief from summer allergies as fall rolls in, while others may be preparing to take their turn. Those that are the least fortunate may have to battle with various forms of allergens throughout the changing seasons.

Common Fall Allergy Triggers

Ragweed – Ragweed continues to pollinate and cause misery to its victims in the form of hay fever or allergic rhinitis right up until the first hard freeze. Ragweed is one of the most abundant and widespread types of pollen, with each plant being capable of producing up to 1 billion grains of pollen each season. There are many other types of weeds that generate pollen, such as sagebrush and goldenrod, that vary depending on the different regions of the country.

Mold – When mold levels are high, mold allergies can be especially troublesome and cause allergic responses for those who are not normally bothered by mold. Mold levels increase with warmer weather and greater levels of moisture. Wet surfaces such as tree bark, brick walkways, and leaf piles provide an ideal breeding ground for mold.

Indoor Allergens – Most have a habit of spending more time indoors during the fall season. If you’re lucky enough to have a home that is a biotechnology clean-room, then you should have no issues. But on average, no matter how hard a person tries to create a contaminant-free environment, you will still be exposed to some degree to the most common indoor allergies – dust and pet dander.

Knowledge is power. Those with allergies or sensitivities to these allergens are accustomed to practices that minimize exposure and help defend against the effects of these airborne irritants. If allergies are a new concern for you, there is an overwhelming amount of tips and advice online, but there are a few basic points to become familiar with.

Allergy Prevention/Reduction Recommendations

Check the pollen count – Pollen count fluctuates daily, even multiple times during each day. Pollen can have a significant impact on those who are allergic. Those allergic to pollen often look to numerous online resources and apps that are available to plan their outdoor activities around the anticipated pollen count. Find one that you like and remember to use it when planning YOUR outdoor schedule.

Minimize mold When the conditions are right, mold can grow anywhere indoors or outdoors. Mold only has two basic requirements to grow – moisture and food. Moisture can be in the form of humidity, condensation, standing water, or water leaks. Mold’s food comes in the form of a surface where the mold can grow on. Ideal surfaces for mold growth are natural or organic in nature such as leaves, paper, wood, and clothing.

Do away with dust – Dust is nearly impossible to get rid of completely as it must be controlled at the source. Despite strong efforts to remove it, dust is extremely difficult to remove as there are numerous sources of dust and its constantly reintroduced into the environment.

Hold back the humidity – The air tends to be more dry in some areas during this time of year, but some regions have a higher level of humidity. Mold and dust mites thrive in more humid environments. Dehumidifiers are very helpful in removing moisture from the air, making it the least ideal conditions for the dust mites and mold to multiply. If you already use a dehumidifier at home or at work, remember to change the humidifier pad regularly.

Improve your IAQ – IAQ refers to Indoor Air Quality. One of the most important things you can do to assist with keeping your air clean is regularly change your air filters (including your air conditioning, furnace and whole house air filter). Your air filter provides an added level of defense against dust. It not only protects your HVAC system components and keep your unit clean, but it also removes dust and allergens from your air.

MERV, MPR or FPR?

merv vs mpr vs fpr ratingFilters can be complicated to understand. Some HVAC systems have the recommended type of filter written on a label that is stuck right on the side of the unit. Other systems leave it up to you to decide what filter you want to use. With all the different sizes available, thicknesses, and types, it’s easy to get confused. On top of it, there are acronyms on the filters that are also part of a filter’s rating system. We’ve talked before about MERV ratings, what they mean and how it relates to the filter you buy. But there are two other acronyms that appear on some filters as well: MPR and FPR. This confuses things even more. What do they stand for? How do you make sense of them all when comparing filters? Is one more efficient than another?

MERV vs. MPR vs. FPR Rating

MERV FILTERS

MERV stands for Minimum Efficiency Reporting Value. Developed in 1987 by ASHRAE (the American Society of Heating, Refrigeration, and Air Conditioning), the MERV systems provides standardized ratings consumers can use to compare the effectiveness of the different air filters available. It provides clarity to what level of filtration can be expected from an air filter with a specific MERV rating. In other words, this means that any MERV 8 rated air filter will filter the same as any other filter with a MERV 8 rating.

MERV ratings (ranging from 1-16) score the performance level of a filter in regards to the removal of airborne particles from 0.3-10 microns in size. A micron is the measurement used for airborne particles. One micron is 1/1000th mm which is equal to 1/25,000ths of an inch. The human eye can see particles beginning around 20 microns; however, in perfect conditions, it is at times possible to see particles as little as 10 microns. To put that into a visual, a dot (.) is just about 600 microns.

The MERV system is the only nationally regulated and independent filtration system.

MPR FILTERS

MPR stands for Microparticle Performance Rating. This rating is exclusive to filters that are manufactured and sold by the home improvement brand 3M in partnership with Filtrete. These filters serve the same function as all other filters – cleaning the air being brought into your HVAC system of allergens, dirt and debris before returning the air back into your home.

MPR ratings (ranging from 300-1900) also gauge the size of the particles they will remove from the air, but only from 0.3-1 micron in size. Filtrete (3M) filters are the only filters that carry the MPR rating and there is currently no independent third-party testing available for comparison to MERV rated filters.

FPR FILTERS

FPR stands for Filter Performance Rating. This rating is also exclusive, but to filters that are manufactured and sold by the Home Depot. Unlike MERV and MPR ratings, the Home Depot does not supply a size range for the particles these filters will remove. Instead, filters are assigned an FPR number (such as FPR 10) for the particle removal measurement.

FPR ratings range from 4-10, with FPR 4 being economy filters and FPR 10 being premium filters. The Home Depot does provide a guidance chart to compare the contaminants the filters will remove; however, FPR ratings to not clarify what a large particle is versus what what a small particle is. Home Depot brand filters are the only filters that carry the FPR rating and there is currently no independent third-party testing available for comparison to MERV rated filters.

US Home Filter Carries AC Filters to Fit All HVAC Units

The biggest difference between these ratings is the makers of the filters themselves. Just remember, the most important thing when choosing an air filter, regardless of rating, is that it is compatible with your HVAC system. No matter which HVAC system you have, every unit needs a quality filter that fits properly in order to keep your indoor air quality clean, your unit running at its maximum efficiency, and your energy costs down.
