Furnace filters are critical to the operation of your furnace. They remove dust and other particles from the air that would otherwise be recirculated through your heating system. This MERV 11 filter captures a good amount of airborne particulates like dust, soot, pollen, pet dander, and more - but still allows enough fresh air into your furnace without causing strong air restrictions.
