An air filtering and treatment apparatus (10), the apparatus (10) including: a housing (12) having an air inlet (14), an air outlet (16), an air passageway (24) between the inlet (14) and outlet (16), and a fan (18) arranged to urge air through the air passageway (24) between the air inlet (14) and the air outlet (16), wherein the housing (12) includes filter (20) arranged to filter air passing through the air passageway (24), and a receptacle (26) located toward the air outlet (16) relative to filter (20). The receptacle (26) is adapted to hold treatment composition (22) such that an evaporable vapour associated with the treatment composition (22) is able to accumulate in a headspace (41) of the receptacle (26), the headspace (41) including at least one aperture (36). The air passageway (24) may be shaped such that air flows substantially perpendicularly past the at least one aperture (36) of the receptacle (26) such that a pre-determined amount of the evaporable vapour is entrained into the filtered air released from the air outlet (16). A system (100) and method are also disclosed.

An atomizing diffuser for gaseous environment cleaning: includes a tank cover covered in a water tank to define an oscillation space in the tank cover so as to enhance the effect of oscillating atomized liquid, a housing shield shielding the tank cover and provided with a water filling hole for allowing direct filling of liquid in the water tank and the oscillation space, and an oscillation device with the oscillator thereof coated with a layer of acid and alkali resistant coating for oscillating the alkaline ionized water and other acid-alkaline cleaning liquids in the oscillation space into gaseous cleaning mist that is outputted to the external environmental space for sterilization, cleaning, deodorization, virus elimination, or air purification, and an umbrella-shaped panel with radial ribs provided in the housing is illuminated by light to show the beauty of a paper umbrella, matching the spray effect.

A disinfection unit configured to be operated in a room having a ceiling includes a detection unit arranged and configured to detect a height of the room and one or more nozzles each being arranged to generate a jet and spray a disinfection fluid into the room. The disinfection unit includes a control unit configured to calculate a quantity of disinfection fluid to be sprayed into the room on the basis of a predefined required degree of purity.

A multifunctional physical store system with automatic sterilization and disinfection functions includes a central process device, and a disinfection device, an order device, a sterilization device, and a serve device that are coupled with the central process device. The system is applied to a physical store. The disinfection device is applied for carrying out the disinfection operation on the environment of the physical store. The sterilization device is applied for carryout surface sterilization on the people entering the store. The order device and the serve device are applied for people to order and acquire meals. Therefore, the application of various devices facilitates a nearly dust-free and sterile environment in the store, lowering the possibility of virus or bacterial infection between people in the operation area and the customers.

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.

Systems and methods for distributing treatment compound to an enclosed environment comprise a storage and distribution assembly for storing a treatment compound, a pipe system for delivering the treatment compound from the storage tank to an environment and an exhaust system configured to exhaust the treatment compound out of the environment.

A steam room for sanitizing people's external body parts and clothes, but also their breathing airways and respiratory tract, to reduce viral load and thereby mitigate the likelihood of spreading or contracting Viral contamination. Steam room has precise temperature and relative humidity control of a heater and mist generator, in which the mist water molecules contain an accurate concentration of a Chlorine or Ethanol based disinfectant, so that the water vapor or combined air/water mixture in the room that comes in contact with the sanitized person reaches but does not surpass the globally permitted concentration of free Chlorine for swimming pools, dressing rooms and spas. The room has thermally isolated quick doors allowing rapid entry and exit, and the signaling to guide the person when to enter, stay and breath, and exit, in the most suitable timing profile for the application.

A sanitizing system for water treatment in appliances that use or that have an associated water cycle where sanitization of the water in the water cycle is beneficial. The system comprises a controller, a biocide, and a biocide injection subsystem, wherein the controller provides a signal to the injection subsystem to release a biocide into a water reservoir contained within the appliance, and further wherein the signal provided by the controller is in response to a signal received by the controller from the appliance.

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.
