About Air Filter Efficiency Ratings

Eliminate heavy odors with these filters that have 30 times the odor removing ability of standard odor-removal air filters. The cardboard frame is treated to resist humidity, and the galvanized steel grill prevents sagging.

These filters meet UL 900 flame retardance requirements. Actual size is up to 5/8" less than trade size.

Odor-Removal Panel Air Filters

Carbon granules in these filters remove odors. They are pleated to maximize filtering surface area without reducing airflow. The cardboard frame is treated to resist humidity.

Actual size is up to 5/8" less than trade size.

Air Filter Rolls

Cut these rolls to the size you need; frames are sold separately.

All meet UL 900 flame retardance requirements.

Rolls with a tacky surface retain particles better than other rolls.

90-ft. and 135-ft. long rolls with a width of 10" or greater come vacuum packed and expand after compression is released.

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.
