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: 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: 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.
