Ultra-Efficiency Box Air Filters

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


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.
