Fiberglass Air Filters

Airex Fiberglass Air Filters are manufactured using the highest quality materials available. The filter media consists of fine threads of glass which are loosely spun on the air entering side and progressively woven tighter on the air exiting side. This design increases dust holding capacity and eliminates the problem of surface loading.

Each fiber is treated with a non-odorous, non-migrating adhesive which helps hold dust within the filter, and allows viscous impingement filtration to occur. The filter media is enclosed in a heavy duty moisture resistant Kraft board frame, and is available with or without front and back #28 Gage metal retainers securely fastened to the frame to increase overall rigidity of the filter. The outer frame indicates size, airflow direction, and the filter's UL Class 2 rating. Ashrae efficiency is less than 20 with a MERV rating of 1-4.

Please measure accurately as we do not accept returned filters due to contamination of filter media.
