The Airzey 20x25x4 MERV 13 filter is designed to improve your indoor air quality for your home and for your family's benefit. Using a pleated design and unique Nanofiber Technology, our filters are able to capture more particles without restricting airflow throughout your home. Our filters are 100% made in the USA and go to support a small, local business based in North Carolina.

Our 4 inch deep filters are specifically designed as a "whole house filter" to be placed in the HVAC central duct work located in the crawl space, attic, or utility closet.
