About Air Filter Efficiency Ratings

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

Rolls with more pores per inch catch smaller particles than rolls with fewer pores per inch.

These rolls meet UL 900 flame retardance requirements.

Mildew-Resistant Snug-Fit Panel Air Filters

A compound inhibits mildew, mold, and fungi growth on these filters. The filter material extends beyond the frame for a tight fit, creating a seal to prevent air from bypassing the filter around its edges. A tacky surface on the filter retains particles.

These filters meet UL 900 flame retardance requirements. Actual size is 3/4" greater than trade size.
