Abstract: An apparatus and method are provided for a breather vent configured to be mounted onto a crankcase breather inlet of an internal combustion engine, such that particulate matter and contaminates are removed from an airstream entering into an interior of the crankcase. The breather vent comprises a base including a fitting receiver configured to retain a breather end of an adaptive fitting. An inlet end of the adaptive fitting is configured to be coupled with the crankcase breather inlet of the engine. A filter medium is fastened to the base and configured to remove the particulate matter and contaminates from the incoming airstream. The filter medium circumferentially surrounds the interior cavity and forms an exterior perimeter of a portion of the cavity. A cap is affixed to the filter medium, such that the filter medium is retained between the base and the cap.

Abstract: An apparatus and method are provided for a cone air filter for a closed intake system of an internal combustion engine. The cone air filter is comprised of a cone-shaped filter medium, retained between a base and a cap, that is fabricated to remove contaminants and particulate matter from an intake airstream. The base is comprised of a flange that couples with an air intake duct of the internal combustion engine. A shell receiver is incorporated into the base and receives a rigid exterior shell, such that the exterior shell surrounds the cone air filter and directs the intake airstream therein. A cap is disposed on an apex portion of the cone air filter and is configured to direct the intake airstream around the apex portion and into the cone-shaped filter medium.

Abstract: An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) home air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within residential spaces. The HVAC home air filter includes a supportive frame having a shape and size suitable to orient the HVAC home air filter within a residential HVAC system. A filter medium is retained within the supportive frame to remove the airborne molecular contaminants and VOCs from air flowing through the residential HVAC system. The filter medium includes a combination of media layers configured to exhibit a relatively high filtration efficiency and a low air pressure drop across the filter medium. The supportive frame includes a plurality of elongate sections and corner sections disposed along perimeter edges of the filter medium to support the filter medium within the residential HVAC system so as direct air through the filter medium.

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 method are provided for a flangeless air filter configured to be mounted onto a flat surface within an air intake system of an internal combustion engine. The flangeless air filter is comprised of a cone-shaped filter medium, retained between a base and a cap, that is fabricated to remove contaminants and particulate matter from an intake airstream. The base includes a pliable seal that forms an airtight connection between the flangeless air filter and the flat surface of the air intake system. A mounting bracket and fasteners may be used to attach the base to the flat surface, compressing the seal there between. In some embodiments, the mounting bracket may be incorporated into, and made a part of the base. A cap is disposed on a top of the flangeless air filter and configured to direct the intake airstream around the cap and toward the filter medium.
