A clean air filter makes a difference
Dirty air filters leave particles like dust, mites, pollen and pet dander in the air, which reduces air quality in your home. Dirty air filters also make your HVAC system work harder to move air, which raises energy bills and shortens the system's life.

Check your owner's manual or enter in your filter dimensions to find the right air filter for your furnace or AC unit.
