HVAC system air filter
First Claim
1. A heating, ventilation, and air conditioning (HVAC) system air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within building spaces, comprising:
- a supportive frame comprising a shape and a size configured for orienting the HVAC system air filter within a HVAC system of a building; and
a filter medium retained within the supportive frame and configured to remove the airborne molecular contaminants and volatile organic compounds from air flowing through the HVAC system, wherein the filter medium comprises a cotton gauze portion comprising at least one layer of cotton gauze disposed between two epoxy-coated aluminum wire screens, the at least one layer of cotton gauze being configured for treatment with a filter oil composition to cause tackiness of microscopic fiber strands comprising the filter medium.

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.
