A face shield system utilizes a headgear with an outer shield and an optional inner side that is proximal to a person wearing the face shield. The headgear may be configured to receive a disinfecting cartridge that neutralize or destroy pathogens in an airflow flowing therethrough. The cartridge may include a neutralizing UV light emitter and a destroying UV light emitter as well as an ionizer. The plenum may include a plurality of baffles to produce a serpentine flow through the plenum. The baffles and the interior of the plenum may be textured and polished and may include catalytic coatings for improving the effectiveness of pathogen destruction and absorbing ions and UV light. An air inlet may allow air from the plenum to pass into the inner side of the shield after the air is disinfected and purified by the UV light emitters.

A system and method for using cold atmospheric plasma to treat an air flow to inactivate viruses and sterilize the air flow. The system comprises a source of a carrier gas, a humidifier connected to said source of a carrier gas, a source of a feed gas, a plasma generator configured to plasmatize said carrier gas into a plasma; and a mixer having an interior chamber, an active electrode inside said interior chamber and connected to an electrical output of said plasma generator, an outer electrode connected to a ground and a dielectric barrier between said inner electrode and said outer electrode, wherein said mixer has a first fluid input port connected to said source of a carrier gas, a second fluid input connected to said source of a feed gas and a fluid output connected to a ventilation system.

A fog generator assembly includes a water vapor generator, a fragrance dispenser, and a mixing element fluidly coupled to the water generator and the fragrance dispenser. The mixing element is configured to mix a fog of water vapor from the water vapor generator with a fragrance from the fragrance dispenser to produce an aromatic fog.

Provided is a chlorine dioxide generation device, suitable for long-term storage, discharging a chlorine dioxide-generating mixture that remains at an object of interest when used to thereby stably exhibit the effect of chlorine dioxide. A chlorine dioxide generation device, comprising: a first container containing a first composition comprising a chlorite and fumed silica; a second container containing a second composition comprising an acidic substance and fumed silica; an outer container housing the first container and the second container; a mixing section that mixes the first composition released from the first container and the second composition released from the second container to produce a mixed composition; and a discharging section that discharges the mixed composition produced by mixing in the mixing section.

A device includes a housing including an inlet and an outlet, the inlet being configured to intake an infectious agents contaminated air, and the outlet being configured to output a sterilized air. The device also includes a superheating heat exchanger configured to increase a temperature of the infectious agents contaminated air by superheating the contaminated air, the infectious agents contaminated air becoming the sterilized air after being superheated. The device further includes a cooling heat exchanger configured to cool down the sterilized air and direct the sterilized air to the outlet of the housing.

A bedside airborne pathogen control apparatus and system. A bedside airborne pathogen control apparatus and system may include an air treatment unit configured to be selectively coupled to a first surface of a hospital bed (e.g., a headboard, a footboard, or a side rail), an air terminal configured to be selectively coupled to a second surface of the hospital bed (e.g., the headboard, the footboard, or the side rail), and a flexible duct extending between the air treatment unit and the air terminal, wherein the flexible duct is configured to deliver a supply of air from an air outlet of the air treatment unit to the air terminal. The air treatment unit and the air terminal may be configured to establish a flow of air around the hospital bed to reduce the dissemination of airborne pathogens from an occupant of the hospital bed.

A pump-fan assembly of an air modification device may include a fan, a pump and a disk. The fan may include a central hub disposed on a top surface of the disk, and a plurality of blades extending from the hub towards an outer circumferential edge of the disk. The pump may include a hollow pump body defining an inner tubular passage between an inlet end and a discharge end. An impeller may be arranged at the inlet end and an outlet port may be arranged at the discharge end. The pump and the fan may be coupled at an interface between the discharge end of the pump body and a bottom surface of the disk. The outlet port may be disposed in the interface and arranged to guide a stream of pumped liquid along the bottom surface of the disk. The disk may define a liquid barrier.

The mixing nozzle has a throat section, a diffuser section, a gas nozzle section, a first liquid suction port, a liquid nozzle section, a second liquid suction port, a baffle plate, and a jetting port. The first liquid suction port liquidly absorbs the solution in the water storage pool from a side of the gas nozzle section toward the gas nozzle tip. The liquid nozzle section extends to the downstream side of the gas nozzle section with intervening the first liquid suction port. The second liquid suction port liquidly absorbs the solution in the water storage pool from a side of the liquid nozzle section toward the liquid nozzle tip. The baffle plate is provided such that the mixed flow mixed in the diffuser section collides in front of a downstream end of the diffuser section, and divides and reverses the mixed flow.

A fragrance and disinfectant dispenser is provided for in-car use, having a container that has an open-topped cavity for receiving a fragrance unit, which unit gives off fragrance when heated to a predefined temperature, and for receiving a disinfectant that is in the form of a liquid or a foam, wherein the cavity is formed by side walls and a bottom connected thereto. An electronically actuatable temperature-control unit is arranged below the cavity and is designed to activate the at least one fragrance unit arranged in the at least one cavity in such a way that the fragrance unit gives off fragrance. A dispensing device is arranged in the cavity, is operatively connected to the disinfectant, and is designed to dispense disinfectant from the container when actuated.
