Ultra-Efficiency Odor-Removal Panel Air Filters
Clear the air of fine particles and odors caused by high levels of pollution, such as wildfire smoke. Rated MERV 13, these filters capture smaller contaminants, such as germs and allergens, more efficiently than filters rated MERV 5 or 7. They contain carbon granules, which absorb odors. All meet UL 900 standards for flame retardance.

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.

Odor-Removal Box Air Filters
Carbon granules in these filters remove odors from the air. The rigid frame won’t bend or twist from sudden changes in airflow, such as those created by variable air volume systems. For a long service life, the V-shape design increases the filtering area and reduces resistance to air.
MERV 8 filters trap dust in common areas such as warehouses and offices.
MERV 15 filters capture fine particles such as bacteria and smoke in labs and other settings where it’s important to keep air pure.
