About Air Filter Efficiency Ratings

Wash and reuse these lightweight filter pads that resist mildew growth. Cut to the size you need; frames are sold separately.

Pads with more pores per inch catch smaller particles than pads with fewer pores per inch.

These pads meet UL 900 flame retardance requirements.
