The 3M Filtrete 4" Allergen Reduction Filter for Honeywell and Trion Air Bear is a high performance air filter designed to fit 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... Less
