A mobile disinfection cart contains: a body, a drive system, a water absorption rake, a brush disc, a lid, an air inlet defined on a rear end of the lid, a sterilization structure accommodated in the cover, located above the chassis, facing the drive system, and communicating with the air inlet, an air outlet defined on the lid, an air conduit communicating with the sterilization structure and the air outlet. The mobile disinfection cart further contains a filter fixed in an air conduit, a storage tank secured on the body and communicating with the brush disc, an accommodation box disposed on the body and being in communication with the sterilization structure, and a power supply fixed on the body and electrically connected with the drive system and the sterilization structure.

An air purifier having a polygonal casing defining one or more inside corners, a cylindrical air filter extending along a center axis within the polygonal casing with a space formed between a radially outwards facing surface of the filter and at least one of the one or more the inside corners of the casing, and a filter cleaner at least partly located in the space. The filter cleaning has a cleaning member, a gear mechanism, at least one UV light source, a motor configured to drive the gear mechanism to thereby drive the radially outwards facing surface of a cylindrical air filter past the cleaning member and the at least one UV light source, and a filter cleaner housing encasing the motor, the cleaning member and the gear mechanism.

A storage apparatus according to an embodiment may include a body having a storage space of storage products and an air purifying module coupled to the body. The air purifying module may include a light emitting diode part disposed along a passage of air to provide ultraviolet light, and a filter part disposed adjacent to the light emitting diode part.

Disclosed is a device for purifying or disinfecting contaminated air in an environment comprising a filter stack comprising a HEPA filter coated with a nanopolymer configured to puncture virus particles, a light chamber comprising UVC light source and an ion generator, where in the device is configured to take in contaminated air at the top of the device and expel purified air downward and away from each end of the device.

Some embodiments of the invention include a filter for a waste tank, the filter including a housing with a pair of end fittings; an inner tube positioned within the housing, the inner tube having perforated walls; and a negatively charged resin positioned between the housing and the inner tube. The first end fitting may be configured to attach to the tank's vent line, and the second end fitting may be configured to attach to external venting tubes such that fumes from the waste tank are configured to flow from the waste tank, through the inner tube of the filter, and away from the waste tank.

A process is provided for removing viruses and micro-organisms from building air by inactivation of those biological elements within an HVAC filter having exuding halogenated material therein. The filter for the HVAC systems has the exuded halogenated material applied with a tackified material via a sequential spraying operation prior to heat curing either of those materials. The filter can subsequently be formed with other laminated materials for increased efficiency, and pleated for use in the HVAC system. Both porous and non-porous substrate fibers can serve as the substrate web for the exuded halogenated material, preferably processed as a non-woven web during air filter fabrication

The present disclosure is directed to a novel redesigned or retrofitted cabin air filtration system utilizing an ultraviolet light, radiation, or an energy matrix membrane and related technology to eliminate toxins such as viruses, bacteria, mold, fungi, rickettsia, protozoa, etc. from the air system in a vehicle, such as an automobile, marine vehicle airplane, etc., thereby improving the current cabin air filter functionality and providing a sterile air distribution environment throughout the cabin of the vehicle or small area.

An air purifier including a body including a suction port and a discharge port, and having an inner space through which air is configured to flow from the suction port to the discharge port, a fan disposed in the inner space of the body and having a side surface separated from an inner wall of the body, a light source module including at least one UV light source disposed in the inner space of the body, a power controller mounted on the inner wall of the body, at least one filter disposed in the inner space of the body, a filter replacement region formed at the body to detachably couple the at least one filter to an interior of the body, a door detachably mounted on the body to expose the filter replacement region and including a door guide member having a groove.

A system includes a mask having a filter. The filter is configured to capture aerosol particles. The filter may be formed from a material that is UVC durable and UVC transmissive. The system also includes a UVC LED configured to emit UVC radiation into the filter.

This present application discloses use of a hydrogen peroxide solution for a filter media cleaning and sanitizing system which is designed to dispense the solution to disinfect an air filter. The system is attached to an existing air filter, allowing the system to lightly mist the filter media with the solution. The invention also adjusts the ions in the air system to eradicate germs, bacteria, viruses, and other airborne pathogens, and functions as a sanitization method for any type of air or HVAC system.
