HVAC Home Air Filter

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 comprises 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 comprises 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 comprises 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.

Substrate processing apparatus and control method of substrate processing apparatus

A substrate processing apparatus includes processing units, an exhaust path, a gas processing apparatus and a controller. Each processing unit is configured to process a substrate by using a chemical. A gas exhausted from the processing units flows through the exhaust path. The gas processing apparatus is provided in the exhaust path to remove a target component contained in the gas. The gas processing apparatus includes a duct, a partition plate and a liquid supply. The duct has therein a flow path. The partition plate divides the flow path into spaces, and is formed of a porous material, through which the gas passes, configured to retain a liquid. The liquid supply is configured to supply a dissolving liquid configured to dissolve the target component to the partition plate. The controller adjusts a flow rate of the dissolving liquid according to operation information indicating an operational status of the processing units.

GROUNDED DETERGENT AIR FILTER
20250256234 · 2025-08-14 ·

An electrostatics-enhanced air filter that produces an electrostatic attraction for dust particles using an electrical ground or electrically charged filter is disclosed. The present invention takes advantage of the mirror-charge effect that spontaneously induces an opposite and attractive charge on the filter that pulls in dust particles. A fibrous filter medium pad is impregnated with a liquidus solution, which is a conductive aqueous electrolyte solution which would capture dust particles. Charges on dust particles would be drained off through the liquidus solution to the ground, preventing the effective electrical potential of the filter from changing. The liquidus solution also contains a detergent that keeps the filter clear of oily air contaminants to maintain conductivity through the filter service life. The liquidus solution contains a wetting agent for engulfing dust particles therein/thereon. The liquidus solution also contains a hygroscopic agent that prevents it from partially drying during its use.

Filter oil formulation

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 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 excellent oxidation stability, possesses good thermal stability, and retains a suitable viscosity at a normal operating temperature of an automobile engine. In an embodiment, the composition comprises 96.74% paraffinic oil by volume, 3.20% polyalphaolefin by volume, and 0.06% red dye by volume. The viscosity of the composition at 100 degrees-C ranges between substantially 7.2 and 7.6 centistokes (cSTs).

REUSABLE MULTI-POCKET AIR FILTER
20260097345 · 2026-04-09 · ·

An apparatus and methods are provided for a reusable multi-pocket air filter to remove contaminants from air within interior building environments. The reusable multi-pocket air filter comprises a multiplicity of reusable filter bags for filtering an airstream. A frame supports the filter bags within an HVAC system. The filter bags are arranged parallel to one another and extend downstream of the frame when the airstream flows into the filter bags. Elongated openings in the frame allow the airstream to flow through the frame into the filter bags. The elongated openings include filter bag retainers for individually coupling the filter bags with the frame. The filter bags can be removed from the frame for servicing without removing the frame from the HVAC system. The filter bags can be cleaned by removing them from the multi-pocket air filter, flushing contaminants from the filter bags, and allowing the filter bags to dry.
