About Air Filter Efficiency Ratings

Long-Life 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 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.

HEPA Long-Life Box Air Filters
Extend the time between filter changes in laboratories, hospitals, and other places with a high risk of airborne contaminants. These filters have tight pleats, which increase the surface area for catching particles. They’re a HEPA filter, so they capture small particles, such as allergens and germs, more efficiently than standard air filters.
Filters with an aluminum frame have a V-shape design that increases the filtering area and reduces resistance to air, leading to an even longer life than filters with a standard design.
