Abstract: 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.

Abstract: An air filter and methods are provided for optimizing filtration of an airstream passing through a volume within an air cleaner cover of an internal combustion engine. The air filter comprises a base plate that includes an inlet receiver for passing the airstream into an air inlet of the engine. A top plate comprises a receiver for fastening the air cleaner cover onto the air filter. Countersinks in the top plate and sleeves extending through the air filter facilitate fastening the air filter onto the air inlet of the engine. The air filter has a tapering height along a length of the air filter to maximize the total surface area of a filter medium within the volume between the air cleaner cover and the engine, and to take advantage of a relatively greater airflow due to a ram air opening in the air cleaner cover.

Abstract: An air filter including two opposing open ends, and a filter area circumferentially enclosing a cavity in between. The first open end frictionally and sealingly engages the filter housing including an air port, while the second end engages the housing to close the second end from passage of air. The filter area may be reinforced to provide a durable, reusable filter. The filter material may be selected to provide depth loading and increase the particulate capacity of the filter.

CPC classification number: G09B25/02
Abstract: An apparatus and a method are provided for a filter airflow demonstrator to provide a visual representation of resistance to air flow through an air filter. The airflow demonstrator comprises a housing that includes an opening configured to receive the air filter. An edge portion of the opening receives a perimeter of the air filter, such that a filter medium of the air filter is disposed over the opening. An electric fan within an interior of the housing draws the air flow through the filter medium into the housing. A transparent stand pipe is disposed atop the housing, such that a lumen of the stand pipe transports the air flow from the interior to an exterior of the housing. A ball within the central lumen travels upwards therein under the action of the air flow to provide an indication of resistance to the air flow through the air filter.

Abstract: An apparatus and a method are provided for a cabin air filter to remove airborne molecular contaminants and volatile organic compounds from a passenger compartment of a vehicle. The cabin air filter includes a supportive frame configured to suitably orient the cabin air filter within a ventilation system of the vehicle. The supportive frame having a shape and size suitable for supporting the cabin air filter within the ventilation system. A filter medium is retained within the supportive frame and configured to remove the airborne molecular contaminants and volatile organic compounds from air flowing through the ventilation system. The filter medium electrostatically attracts and agglomerates contaminants within the air flowing through the air filter. In some embodiments, the filter medium includes fibers treated with antimicrobial molecules configured to destroy microbes. In some embodiments, the filter medium includes fibrous materials configured to release a fragrance into the passenger compartment.

Abstract: An apparatus and methods are provided for an air cleaner to be mounted onto an air inlet of an internal combustion engine. The air cleaner comprises an air filter that includes a filter medium disposed between a curved base and a cover. The curved base provides an interface between the air filter and the air inlet, and comprises a shape that provides clearance between the curved base and an electric choke installed onto a carburetor comprising the air inlet. The cover secures the air filter and the curved base to the air inlet such that an airstream is drawn through the filter medium and is conducted into the air inlet. A raised portion of the cover is configured to cooperate with the curved base to ensure a desired volume of the airstream is available to the air inlet at substantially all engine speeds.

Abstract: An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) system air filter for a building ventilation system. The HVAC system air filter comprises a supportive frame configured to orient the HVAC system air filter within the building ventilation system. A composite filter medium retained within the supportive frame comprises a cotton gauze portion and an electrostatic portion. The cotton gauze portion is configured for treatment with a filter oil composition to enhance airflow and filtration of air flowing through the composite filter medium. The electrostatic portion is configured to electrostatically attract and agglomerate airborne molecular contaminants and volatile organic compounds (VOCs) as small as 0.001 microns in diameter. In some embodiments, the composite filter medium comprises substances configured to release a fragrance into air passing through the composite filter medium.
