About Air Filter Efficiency Ratings

These MERV 14 air filters capture particles down to 0.3 microns. They have a rigid frame that withstands fluctuations in airflow, such as those created by variable air volume systems.

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

Long-Life Ultra-Efficiency Box Air Filters

Four 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 rigid frame that withstands fluctuations in airflow, such as those created by variable air volume systems.

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

Eight-panel filters have more surface area than four-panel filters for an even longer service life.
