About Air Filter Efficiency Ratings
More
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.
