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.

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 15 filters capture fine particles such as bacteria and smoke in labs and other settings where it’s important to keep air pure.

Bag Air Filters

The deep pockets on these filters maximize filtering surface area with minimal airflow resistance. Actual size is 5/8” less than trade size.
