About Air Filter Efficiency Ratings

Rated MERV 13, these filters capture particles down to 0.3 microns. Use in data centers, hospitals, and other locations that require extra-clean air. These filters have pleats that create a large surface area for filtering without reducing airflow. The cardboard frame is treated to resist humidity, and the galvanized steel grill prevents sagging.

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

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.
