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.

Long-Life Box Air Filters

Four Panels

Six Panels

Eight Panels

Multiple panels maximize filtering surface area for long service life. These MERV 14 air filters capture particles down to 0.3 microns. They have a V-shape design and a rigid frame that withstands fluctuations in airflow, such as those created by variable air volume systems. The more filter panels they have, the more filtering surface they have for a longer service life.

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

Box Air Filters

The rigid frame on these filters withstands fluctuations in airflow, such as those created by variable air volume systems.

MERV 14 filters provide a higher level of filtration than MERV 11 filters and are more effective at capturing finer allergens and viruses for an enhanced level of protection. These filters are often used in environments to protect against airborne contaminants from wildfire smoke and in regions with high pollution levels.

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