The present disclosure is directed methods and apparatus of a V-Bank filtration system capable of maintaining desired air flow rates while effectively filtering the air. These methods and apparatus charge particles and then capture those particles in a filter medium. Once captured in the filter medium, micro-organisms are exposed to high energy electric fields that may degrade and ultimately destroy the captured micro-organisms. Electric fields generated within portions of the V-Bank filter apparatus may also be contained within the portions of the filter apparatus based on exterior parts of these portions being grounded at Earth ground potential. Magnetic fields (or electro-magnetic fields) associated with the generated electric fields may also be contained within the portions of the apparatus based on the exterior parts of these portions being grounded.

The methods used to build the apparatus allows destroying airborne pathogens like bacteria, mold, mildew, allergens and deactivates viruses such as SARS CoV-2. The apparatus supports air circulation system that contains filter which comprising array of Ultraviolet (UV) Light Emitting Diode (LEDs) of 262-nm wavelength, AKA UVC, are used.

An air purifier includes a shell, a wind turbine and an air filter layer. The shell includes at least one air inlet and at least one air outlet, and an air passage is defined between the at least one air inlet and the at least one air outlet. The wind turbine is located in the air passage. The air filter layer is located in the air passage and includes a filter screen. The air filter screen includes a carbon nanotube structure including a plurality of carbon nanotube films stacked and crossed with each other. The carbon nanotube structure includes a plurality of micropores. A diameter of the micropores is ranged from about 1 micrometer to about 2.5 micrometers.

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.

An air treatment device having a flexible air hose, duct or gooseneck member. The air hose, duct or gooseneck member permits an inlet end thereof to be positioned in proximity to a patient so that a negative pressure can be created around the patient so that air can sucked or vacuumed into the system whereupon it is treated as the air flows through the system.

A bio-functional air filter medium is provided with a at least one particle filtration layer that retains particles and at least one bio-functional carrier coated with or having embedded therein antimicrobial, anti-viral and anti-allergenic materials. An air filter element having the bio-functional air filter medium is also disclosed. The bio-functional air filter medium is adapted to bind and capture allergens and block metabolism of bacteria, and provide anti-viral activity to effectively inhibit/deactivate viruses, all while filtering air in high flow, low pressure drop residential, HVAC or air purifier applications.

A filtration article including a composite filtration structure, a seal region positioned within the composite filtration structure, and an attachment weld that interconnects the seal region and an outer casing is provided. The composite filtration structure includes a stacked filter material including at least two fluoropolymer membranes and a support layer. The support layer may be formed of a thermoplastic or thermoset polymer. When heated, the polymer in the support layer melts and flows into the fluoropolymer membranes. In exemplary embodiments, the polymer is imbibed through the thickness of the fluoropolymer membranes. The attachment weld may be positioned at any location within the seal region so long as the attachment weld is positioned a distance from the outer periphery of the composite filtration structure. The filtration article is small in size, is lightweight, and may be used as a sterilizing grade filter. Methods of producing the filtration article also provided.

An air filtration device including a housing that includes an air intake and a blower motor mounted within the housing, wherein when the blower motor is in operation, the blower motor generates an air flow from the air intake through an air duct extending vertically from the housing. The air filtration device also includes an air outlet at a distal end of the air duct, wherein the air outlet comprises at least one aperture, wherein when the blower motor is in operation, the air outlet discharges the air flow in a horizontal plane over an occupied zone from a region of the air duct having a vertical height that is less than or equal to twelve inches, wherein the region of the air duct for the air outlet is disposed at least thirty-six inches above the air intake. The air filtration device also includes an air filter.

An air purification device for use in an air management system includes a housing formed from a polymer matrix composite structure and a filter arranged within the housing. The filter is formed from a porous composite structure including a plurality of filter fibers such that air is configured to flow through the filter. Microbes within the air are configured to contact the plurality of filter fibers.

Disclosed is a method and system for the mitigation of risk of exposure to contaminants and providing information thereof.
