Guaranteed to perform for a lifetime, a permanent filter saves you money. As it replaces disposable 1” filters, it reduces indoor pollutants like mold spores, cement dust and cleaning chemicals. The patented stage loading, peak and valley design traps larger particles on the outside and smaller particles on the inside. This design increases the filter's efficiency. The filter includes no foam or metal that could compromise its performance. Simply wash it every three months in the opposite direction of the airflow, allow it to dry completely and reinsert it. When washed regularly, this permanent filter provides you with a lifetime of clean indoor air.
