Guaranteed to last for life, a washable filter provides affordable, clean indoor air. Rated MERV 5, this filter captures large particles of dirt, dust and pollen. It uses a stage loading, peak and valley design to capture large particles on the exterior and smaller particles in the inside. It provides unrestricted airflow when vacuumed once a month and washed every three months. Without foam and metal, the filter does not corrode or degenerate over time. These features enable the filter to provide clean air for life.

We live in a small town that does not have certain air filter sizes. This is great and I can clean it and reuse it!
