Reusable air filter system and method
A reusable air filter and methods are provided for filtering air being conducted to an air intake of an internal combustion engine. The reusable air filter comprises a filter medium configured to pass an airstream and entrap particulates flowing within the airstream. The filter medium is comprised of cotton gauze disposed in a sinusoidal arrangement that provides a filtration surface area that is larger than a perimeter area of the filter medium. An end cap and base may be configured to retain the filter medium therebetween. The base provides an interface between the air filter and an air inlet of the engine. The filter medium may be disposed in a flat, panel shape that is bordered by a supportive tray. Support rods may be embedded within the tray to prevent bowing of the tray due to air pressure when coupled with an air box of the engine.
1. A reusable air filter for filtering air being conducted to an air intake of an internal combustion engine, comprising:
a filter medium configured to pass an airstream and entrap particulates flowing within the airstream; and
a reinforced end cap and a base configured to retain the filter medium therebetween, wherein a reinforcement ring is disposed within material comprising the reinforced end cap, the reinforcement ring being configured to provide structural integrity to the reusable air filter wherein the end cap having a generally square shape having a plurality of straight sides and a plurality of inwardly protruding waved sides.
2. The reusable air filter of claim 1 , wherein the reinforcement ring includes a plurality of holes configured to facilitate bonding of the material comprising the reinforced end cap with the reinforcement ring.
3. The reusable air filter of claim 1 , wherein the reinforcement ring includes one or more protrusions.
4. The reusable air filter of claim 3 , wherein the one or more protrusions extend radially from a center of the reinforcement ring.
5. The reusable air filter of claim 1 , wherein the base is configured to support the air filter and provide an interface between the air filter and an air inlet of the internal combustion engine.
6. The reusable air filter of claim 5 , wherein the interface is comprised of an inlet receiver configured to be coupled with any of an intake pipe, a turbocharger, and a manifold of the internal combustion engine.
7. The reusable air filter of claim 5 , wherein the base comprises any of a variety of ridges and raised portions to optimally engage with the air inlet.
8. A reusable air filter for filtering air being conducted to an air intake of an internal combustion engine, comprising:
a filter medium configured to pass an airstream and entrap particulates flowing within the airstream; and
a reinforced end cap disposed at a first end of the filter medium, wherein a reinforcement ring is disposed within material comprising the reinforced end cap, the reinforcement ring being configured to provide structural integrity to the reusable air filter wherein the reinforced end cap comprising at least a plurality of inwardly protruding waved sides.
9. The reusable air filter of claim 8 , wherein the reinforcement ring includes a plurality of holes configured to facilitate bonding of the material comprising the reinforced end cap with the reinforcement ring.
10. The reusable air filter of claim 8 , wherein the reinforcement ring includes one or more protrusions.
11. The reusable air filter of claim 10 , wherein the one or more protrusions extend radially from a center of the reinforcement ring.
12. A method for a reusable air filter for filtering air being conducted to an air intake of an internal combustion engine, comprising:
configuring a cleanable filter medium to entrap particulates flowing within an airstream;
forming the cleanable filter medium into a shape that facilitates coupling the reusable air filter with an air box, such that an entirety of the airstream is passed through the filter medium;
contouring the cleanable filter medium to provide a filtration surface area that is larger than an area of the shape; and
coupling the filter medium with one or more support structures including a reinforced end cap and a base that maintain the shape of the filter medium, wherein a reinforcement ring is disposed within material comprising the reinforced end cap, the reinforcement ring being configured to provide structural integrity to the reusable air filter, wherein the reinforced end cap comprises at least a plurality of inwardly protruding waved sides.
13. The method of claim 12 , wherein the reinforcement ring includes a plurality of holes configured to facilitate bonding of the material comprising the reinforced end cap with the reinforcement ring.
14. The method of claim 12 , wherein the reinforcement ring includes one or more protrusions.
15. The method of claim 14 , wherein the one or more protrusions extend radially from a center of the reinforcement ring.
16. The method of claim 12 , wherein forming further comprises forming the cleanable filter medium into any one of a cylindrical shape, a cone shape, and a cube shape having waved sides.
17. The method of claim 12 , wherein coupling further comprises implementing the support structures as the end cap and the base that is configured to couple with an air inlet of the internal combustion engine, the air inlet being any of an intake pipe, a turbocharger, and a manifold of the internal combustion engine.
18. The method of claim 14 , wherein forming further comprises forming the cleanable filter medium into any one of a square shape, a rectangle shape, and a trapezoid shape.
