About Air Filter Efficiency Ratings

Rated MERV 11, these filters capture particles down to 1 micron. Use in data centers and other locations that require extra-clean air. These filters have pleats that create a large surface area for filtering without reducing airflow. The cardboard frame is treated to resist humidity, and the galvanized steel grill prevents sagging.

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

High-Efficiency Long-Life Panel Air Filters

With tight pleats, these filters have a larger surface area than filters with standard pleats for improved efficiency and an even longer life. These filters strike a good balance of filtering efficiently while allowing airflow, making them a more cost-effective option than higher rated filters. All are effective at capturing common allergens such as dander, mold spores, and pollen. Use them in data centers and other locations that require extra-clean air.

Box Air Filters

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

MERV 11 filters capture common allergens, such as dander, mold spore, and pollen, so they are often used in data centers and other locations that require extra-clean air. They strike a good balance between filtration efficiency and airflow.

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