Furnace Filters 101–Why are they important?

Clean vs dirty filters

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 air filters 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!)
