20" X 24" X 1" Permanent Washable Filter These premium quality washable filters are guaranteed to last a lifetime. They are interchangeable with 1" disposable filters and can be easily cleaned and used again and again. Never buy another filter.
Washable filters last a lifetime as they clean your indoor air. This permanent filter earns a MERV 5 rating for reducing airborne contaminants. It captures dust, pollen and mold spores. The efficient stage loading, peak and valley design traps large particles on the outside and smaller particles on the inside. Foam- and metal-free, the filter will not degrade, clog or oxidize. Backwash it once every three months against the airflow then reinsert it after it dries completely. Because it is a permanent filter, it lasts a lifetime as it is environmentally friendly.
Make sure your filter fits snug it its slot or cabinet. Gaps that allow air to bypass the filter can significantly reduce its effectiveness.
