This 3M Filtrete 4" 1550 Healthy Living Ultra Allergen Reduction Filter for Aprilaire Space-Gard, Honeywell, and Trion Air is a high performance air filter designed to fit 20x25 whole house media air cleaners installed in your furnace or central air conditioner. The Filtrete 4" Allergen Reduction Filter contains electrostatically charged fibers, which enable this filter to attract and capture 97% of airborne allergens and particles, such as pollen, mold spores, and dust mite debris. When your furnace or central air conditioner fan is on, air circulates in your home and passes through the filter. This 3M Filtrete filter captures particles in two ways: mechanically and electrostatically. All filters perform mechanical filtration by providing a barrier that captures particles from the air passing through the filter. Filtrete filters also have electrostatically charged fibers that work like tiny magnets to attract and capture particles.

You may need to change your filter more often if your home has construction work in progress or very polluted indoor air. Also, running your HVAC fan continuously will improve your air quality but will shorten the life of the filter.
