Filtrete 20 in. x 20 in. x 1 in. MERV 2 Air Filter

The Filtrete 20 in. x 20 in. x 1 in. MERV 2 Air Filter provides reliable basic filtration for residential heating and cooling systems. Designed for use in furnaces, air conditioners, and HVAC systems, this non-electrostatic filter outperforms standard fiberglass filters by capturing large airborne particles such as household dust and lint. Maintaining a clean air filter helps optimize airflow and prevents heating and cooling equipment from overworking and wasting energy. For optimal performance and indoor air quality, replace the filter at least every 90 days and track filter life using the Filtrete Smart app.
