Abstract
An air filter may include a synthetic foam filter region, and a natural fiber filter media region, having pileous, absorbent, wickable natural fibers. The foam filter region and the natural fiber filter region are supported between pleated influent and effluent mesh layers. Alternatively, a synthetic fiber filter media region having absorbent spunbond polyester filters may also be included. Oil may also be disposed in one of more of the filter media reqions. Fiber regions may also have layers disposed in gradient density arrangement.
Claims17
A pleated air filter comprising:
- a influent mesh layer and a corresponding effluent mesh layer;
- one or more layers of synthetic foam between the influent mesh layer and the effluent mesh layer;
- and
- one or more layers of natural fiber filter media formed from a pileous, absorbent, and wickable natural fiber between the one or more layers of synthetic foam and the effluent mesh layer.
A pleated air filter comprising:
- an influent mesh layer and a corresponding effluent mesh layer for supporting filter media;
- one or more layers of synthetic foam between the influent mesh layer and the effluent mesh layer;
- one or more layers of cotton fiber filter media formed from a pileous, absorbent, and wickable natural fiber between the one or more layers of synthetic foam and the effluent mesh layer;
- one or more layers of spunbond polyester fiber filter media between the one or more layers of cotton fiber filter media and the effluent mesh layer;
- and
- an efficacious amount of oil disposed in the one or more layers of synthetic foam and the one or more layers of cotton fiber filter media.
