Abstract

A filter assembly includes a filter pad comprising fibers including natural, synthetic and/or hybrid fibers. A stabilizer frame formed of a non-metallic material may be imbedded in the filter pad. The stabilizer frame may be configured to provide support to the filter pad to maintain the filter pad in a generally flat configuration. In accordance with a particular embodiment, the filter pad may be comprised of at least first and second fibrous mats that are coupled together. In this embodiment, the stabilizer frame may be disposed between and coupled with the first and second fibrous mats.

Claims (18)

1. A method of manufacture, comprising:

coupling a filter pad comprising fibers selected from the group consisting of natural fibers, synthetic fibers and hybrid fibers, with a stabilizer frame; and

wherein the stabilizer frame is embedded in the filter pad, the stabilizer frame being configured to provide support to the filter pad to maintain the filter pad in a generally flat configuration.

2. The method of claim 1 , wherein the filter pad is comprised of at least first and second fibrous mats being coupled together, and the stabilizer frame is disposed between and coupled with the first and second fibrous mats.

3. The method of claim 1 , wherein the filter pad is formed from a single fibrous mat that is coupled with the stabilizer frame, and wherein each of four edges of the mat are lapped over respective edges of the stabilizer frame.

4. The method of claim 1 , wherein the fibers include a blend of wool and synthetic fibers.

5. The method of claim 1 , wherein the fibers include viscose fibers.

6. The method of claim 1 , wherein at least a portion of the fibers are treated with a solution that is fire resistant or fire retardant.

7. The method of claim 1 , wherein the stabilizer frame is formed of fiber board material.

8. A method of manufacture, comprising:

blending wool fibers with flame resistant viscose fibers;

carding the blend into a fiber web;

spraying the fiber web with a binder;

needle punching the fiber web into a non-woven blanket; and

applying a bonding emulsion to the wool fibers.

9. The method of claim 8 , further comprising applying a vacuum to the non-woven blanket.

10. The method of claim 9 , further comprising passing the non-woven blanket through an oven at over 280 degrees Fahrenheit.

11. The method of claim 10 , further comprising coupling a stabilizer frame with the non-woven blanket.
