A clean furnace air filter means a cleaner home or business environment. Regularly changing your furnace's air filter helps improve the quality of air in your home or business by reducing the amount of airborne allergens such as dust, pollen, pet dander, mold, and smoke.

With time, air filters collect enough airborne particles to become blocked, eventually doing more harm than good. Changing your filter regularly helps reduce the amount of dust circulating in your home, and cleans the air you breathe more effectively.
