Did you know your air filter is a huge factor in your indoor air quality?
Air filters act as the front line for protecting your indoor air quality. They trap airborne pollutants like dust, dirt, pet dander, and pollen and keep them from getting into your heating and cooling system. But air filters can be confusing if you’ve never bought or changed them. Here’s what you need to know.
What the Heck Does an Air Filter Do?
An HVAC air filter has several jobs. First, they protect your heating and cooling equipment by keeping out damaging dust and debris which can get into the system and cause wear and tear, compromising performance and reducing efficiency.
Second, air filters work to maintain the indoor air quality in your home by preventing those same airborne pollutants from recirculating throughout your house through the heating and cooling system.
How Often Should You Change Air Filters?
HVAC filters need changing every six months at the very least, but that isn't really often enough. Ideally, a new filter is necessary every 90 days to keep your system functioning properly and your indoor air clean.
How Can I Tell What Size Air Filter I Need?
Air filters come with three measurements: height, width, and depth. Every filter should have a series of measurements on them, such as 20"x20"x1". You can look at the filter currently in your HVAC equipment and read the measurements that should be on the side of the cardboard frame of the pleated filter. If you can't read the print, go ahead and measure the filter yourself. If there is no filter, refer to the manual or look up the information online based on manufacturer and model number.
