Foldable air filters and methods of use thereof
Foldable filter assemblies and methods of use thereof are disclosed. An air filter assembly including a frame having opposed substantially rigid end members and a flexible side member, the end members being connected to the flexible side member, and an air filter media connected to and disposed within the frame such that the frame is adapted to be disposed in a planar use position, and the end members of the frame are adapted to be moved toward each other prior to installation into the planar use position.
1. An air filter assembly comprising:
a frame having opposed substantially rigid end members and a flexible side member, the end members being connected to the flexible side member;
an air filter media connected to and disposed within the frame such that the frame is adapted to be disposed in a planar use position, and the end members of the frame are adapted to be moved toward each other prior to installation into the planar use position, wherein the side member is constructed at least in part from plastic tubing.
2. The air filter assembly as defined in claim 1 , wherein the end members are constructed at least in part from a U-shaped channel.
3. The air filter assembly as defined in claim 1 , wherein the frame is made of at least one plastic material.
4. The air filter assembly as defined in claim 1 , further comprising a first webbing connected to at least a portion of the frame.
5. The air filter assembly as defined in claim 4 , further comprising a second webbing connected to at least a portion of the frame, and wherein the air filter media is located in a space defined by the frame and the webbings.
6. The air filter assembly as defined in claim 5 , wherein the webbings comprise a material adhered to at least a portion of the frame.
7. The air filter assembly as defined in claim 5 , wherein the webbings comprise a material welded to at least a portion of the frame.
8. An air filter assembly comprising:
a frame having opposed substantially rigid end members and a flexible side member, the end members being connected to the flexible side member;
an air filter media connected to and disposed within the frame such that the frame is adapted to be disposed in a planar use position, and the end members of the frame are adapted to be moved toward each other prior to installation into the planar use position, wherein the side member is constructed at least in part from a section of chain.
9. The air filter assembly as defined in claim 8 , wherein the frame is made of at least one metallic material.
