What IS an air filter anyway?

An air filter is a vital part of your home’s forced air HVAC (heating, ventilation, and air conditioning) system. Most homes have at least two filters that stand guard over your home’s air; their specific job is to remove bacteria and harmful particles, regularly cleansing the air.

Why are filters important?

100% of the air in your home passes through a filter, typically twice every hour. Since clean, quality air filters keep the air in your home fresh, the people inside stay healthier. A quality filter captures the harmful bacteria typically found in sneezes, coughs, viruses and molds, as well as pollutants like dust and car fumes.

Clean filters also keep your HVAC system healthy—they enable it to run more efficiently, keep repair costs to a minimum, and reduce monthly energy bills. About half of your monthly energy bill is attributed to HVAC, and keeping clean air filters is the single most effective way to improve HVAC efficiency. Clogged filters make the HVAC work harder as it conditions your home, which raises your energy bill. (And if there are no filters, the coils will clog, which is even worse for your system.)

How often should I change filters?

We recommend changing filters at least every 3 months, but every 1 to 2 months will usually serve you better (especially if you have a busy lifestyle, family with allergies, pets in the home, etc.). If you want help choosing the delivery schedule that fits your individual needs, just call or email. We’re here for you.

Regular filter changes cut 5% - 10% off your energy bill every month
according to the Environmental Protection Agency (EPA).

Where are air filters located?

Air filters can be found inside the return vents in your home. These returns might be on the ceiling, wall, or in the system itself.

Most homes have 2 or 3 returns inside the house, or alternatively, two 5” filters that go within the HVAC system itself. Typically the inside returns are more accessible, which makes filter changes easier in these locations.

What about different sizes?

Filters for returns come in all sorts of sizes—one size rarely fits all, even within one house. Dimensions range from 10” x 10” to 30” x 36.” Most (but not all) filters are 1” thick but occasionally, homes will have 2”–5” thick filters.

How do I determine filter size?

Sizing filters is easy. If there is an old filter in the return, the size should be listed on the side of the filter. Remember that each home typically has different sizes throughout, so you’ll want to check sizes at every return.

If there’s no filter within the return, simply measure the length and width of the space. You’ll want to get the exact dimensions to ensure a snug fit for maximum filtration.

How do I install an air filter?

Changing an air filter is easy. Just open the return, pop out the old filter and securely put the new one in its place (following the directional arrows to ensure proper airflow). Then close the return. That’s all there is to it—changing filters is a snap!
