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.

Odor-Removal Air Filter Pads

With a higher carbon concentration than odor-removal air filter rolls, these pads handle heavier odors. Cut to the size you need; frames are sold separately.

All meet UL 900 flame retardance requirements.

Pads with a carbon concentration of 375 g/sq. ft. provide greater odor control than other pads and can handle ammonia, hydrogen sulfide, and other gases. They are often used in hospitals and laboratories.

Air Filter Rolls for Automatic Roll Machines

Polyester Plastic

Fiberglass

Replace the filter roll in your automatic filtering equipment. The filter is wrapped onto a core; use the pull tabs for installation.

These rolls meet UL 900 flame retardance requirements.

Polyester plastic rolls capture more particles than fiberglass. Fiberglass rolls have a tacky surface that helps them retain particles.
