The Fiberglass Air Filter is made of fiberglass material, designed with small continuous fibers to allow for the greatest dust holding capacity. An adhesive is applied to prevent fiber migration into the air ducts. The pad is enclosed in a chipboard frame. Available in both stock and special sizes.

The Fiberglass is progressively dense and the very small continuous fibers are engineered to give the highest filtration possible.

Stock 1″ Fiberglass filters are made with a Fiberglass scrim backing. This allows for safe installation and removal, makes discarding of the filter safe and easy and allows for a tighter seal to the frame.

​

Stock 2″ Fiberglass filters are made with a conventional box frame,. The media is loosely woven in the front, catching the larger particles of the dust and dirt. The media becomes denser as the media progresses until the final layer of dense fiberglass, which takes out the fine particles.
