Filtrete 20 in. x 20 in. x 1 in. Micro Allergen Air Filter

The Filtrete 20 in. x 20 in. x 1 in. Micro Allergen Air Filter delivers reliable filtration performance for residential HVAC, furnace, and air conditioning systems. Designed with advanced pleated filter media featuring an MPR 1000 and MERV 11 rating, it effectively attracts and captures micro-particles such as lint, pollen, dust, pet dander, smoke, and smog while maintaining consistent airflow throughout your home. For optimal heating and cooling system efficiency, replace your home air filter at least every 90 days. Regular filter replacement prevents reduced airflow, helping your HVAC system operate smoothly and maintain cleaner indoor air quality.
