About Air Filter Efficiency Ratings

Compare MERV rating, efficiency, and particle size to find the right filter for your location—from warehouses and offices to hospitals and labs.

Reusable Air Filter Rolls

Wash and reuse these rolls. Cut to the size you need.

These rolls meet UL 900 flame retardance requirements.

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

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.
