20x24x4 Merv 11 Furnace Air Filter

Description

Our MERV 11 filters effectively remove 91% of airborne particles. This filter eliminates allergens such as dust mites, pollen, mold spores, pet dander, dust and smog. Our advanced pleat technology provides less airflow resistance resulting in less pressure drop, which allows air-handling systems to stay cleaner and operate more efficiently. This filter is ideal for allergy sufferers. The electrostatically charged, 100% synthetic graduated density filter media is continuously bonded to a 30-gauge galvanized and corrosion resistant expanded metal support grid. Controlled pleat spacing maximizes the filter media surface area and dust holding capacity. The filter media has an effective open area of 96%, and is resistant to a wide range of chemicals, does not absorb moisture and will not support microbial growth.
