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.

Abstract: A filter oil composition and a method for removing airborne molecular contaminants from air are provided. The composition includes a first portion comprising paraffinic oil by volume of the composition, a second portion comprising polyalphaolefin (PAO) by volume of the composition, and a third portion comprising red dye by volume of the composition. Applying the filter oil composition to a cotton air filter material causes tackiness throughout the air filter material, thereby enhancing filtration of air passing through the filter. The composition generally is substantially non-reactive, has an excellent oxidation stability, possesses good thermal stability, and retains a suitable viscosity at a normal operating temperatures of an automobile engine. In an embodiment, the composition comprises 96.74% paraffinic oil by volume, 3.20% polyalphaolefin (PAO) by volume, and 0.06% red dye by volume. A viscosity of the composition at 100 degrees-C ranges between substantially 7.2 and 7.6 centistokes (cSTs).

Abstract: An apparatus and methods are provided for a filtered cap air filter configured to be coupled with an air intake system of an internal combustion engine. The filtered cap air filter comprises a filter medium that is retained between a base and a filtered cap. The filter medium and the filtered cap are fabricated to remove contaminants and particulate matter from an intake airstream. In some embodiments, the filter medium and filtered cap may be configured to be treated with a filter oil composition to enhance air cleaning properties of the filter media. Wire supports may be incorporated into the filter medium and filtered cap to provide additional strength and durability to the filtered cap air filter. The base includes a flange and an opening that form an airtight connection between the filtered cap air filter and an air intake duct of the air intake system.

Abstract: An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within building spaces. The air filter comprises a support frame having a shape and size suitable to orient the air filter within a HVAC system. A compound filter medium is retained within the support frame to remove the airborne molecular contaminants and VOCs from air flowing through the HVAC system. A portion of the first media layer is pleated and may comprise a combination of media layers configured to exhibit a relatively high filtration efficiency and a low air pressure drop across the filter medium. A second portion of the filter medium is coupled to the first portion and maintains a uniform distribution of the pleats with the first portion.

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 multiple inlet air box to communicate an airstream through an air filter to an air intake duct of an internal combustion engine of a vehicle. The multiple inlet air box is comprised of a housing that supports the air filter within an interior of the housing. A mount portion within the housing fixedly receives a base of the air filter. Multiple air inlets couple with corresponding air inlet ports of the vehicle to direct the airstream into the multiple inlet air box. A duct directs the airstream from the multiple air inlets to the interior of the housing. A conduit communicates the airstream from an interior of the air filter to the air intake duct of the internal combustion engine.
