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.

Save energy and improve air quality with replacement furnace filters and air conditioner filters from Sears PartsDirect. Sears PartsDirect has top air filter brands such as BMC Air Flow and DuPont, at great prices.

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