The Filter helps remove Dust, Allergens, Pollen, Mold Spores, Hair and other particulates out of the air we breath indoors. It also helps keep the components of our HVAC system protected as well from these same airborne contaminates.

Dirty Air filters can cause a number of problems. For instance they can collapse and block Air Handlers or add additional contaminates to air ducts or fan motors.
