The germicidal panel light has an air guiding plane in the mounting cavity nearby the air inlet, so air can be guided into the mounting cavity, air flows slowly, and noises are reduced.

Provided is an indoor air cleaning device for a vehicle using a nonthermal plasma and an operation method thereof, and more particularly, to an indoor air cleaning device for a vehicle using a nonthermal plasma, in which ozone is generated by a nonthermal plasma through corona discharge and an air purifying filter is sterilized through strong oxidization action of ozone, achieving more hygienic and continuous management, static electricity of an electrostatic filter is recharged with the controlled magnitude of applied voltage to maintain the best purification performance of the filter, and negative ions beneficial for human body are generated, creating pleasant indoor air conditions.

A system comprises an ozone conduit in fluid communication with an aircraft door seal configured to seal the ozone conduit to an aircraft door. An ozone source is in fluid communication with the ozone conduit for supplying a flow of ozone gas (O.sub.3) to an aircraft interior through the ozone conduit and aircraft door seal. The ozone conduit can be an ozone inlet line, and an ozone outlet line can be in fluid communication with the aircraft door seal for removal of ozone from the aircraft interior.

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 refrigerator has an air sanitation device. The air sanitation device includes: a housing; an air channel located in the housing and having an air inlet and an air outlet; a fan located in the air channel, to force air to enter the air channel from the air inlet, and then be discharged out of the air channel from the air outlet; and an air detection device and/or an air purification device located between the air inlet and an inlet of the fan.

A germicidal device includes a purification/disinfection and LED lighting member configured to generate UVC light and negative air ions for destroying microorganisms and removing odors in a space in which the purification and sterilization member is placed; a sensing member configured to detect at least one event occurred in said space in real time; and a microcontroller unit coupled with the purification and sterilization member and the sensing member for controlling operations of the purification and sterilization member in a respective state in accordance with the at least one event occurred in said space and energy saving. The UVC light has one or more wavelengths in a range of about 100-400 nm.

The present disclosure provides a medical device. The medical device may include a gantry, a table, and one or more disinfection devices. The gantry may include a bore configured to accommodate an object for scan. The table may be configured to support the object and move the object into the bore. The one or more disinfection devices may be configured for disinfection.

An ion generating device can include a housing having an opening, an anode and a cathode disposed within the housing and having a space between them in fluid communication with the opening, a power source having a negative terminal and a positive terminal with a first connection between the negative terminal and the anode and a second connection between the positive terminal and the cathode, and an air mover disposed to direct an air flow through the space and out of the opening.

An air purifier and a purifying method are provided. The air purifier includes a housing, a sterilization and ozone-generating unit, a physical filter, a first ozone-removing unit, and a cover. The housing has a sidewall and a bottom surface to define a processing space, wherein an upper end of the housing has an air inlet and the sidewall has an air outlet. The sterilization and ozone-generating unit is disposed in the processing space. The physical filter is disposed in the processing space, extends along the sidewall, and surrounds the sterilization and ozone-generating unit. The first ozone-removing unit is disposed between the physical filter and the sidewall. The cover is openably disposed at the air inlet.

An apparatus for sanitising a target comprises a supply of a sanitising substance comprising a gas and/or plasma of nitric oxide and/or ozone, and a conduit arranged to direct the sanitising substance onto a target to sanitise the target. FIG. 13(a) shows a sanitiser product generator device 1200 which is arranged to release a sanitising product into an elevator 1220 via channel 1240. The sanitising product will destroy bacteria and virus within a mixing chamber before being released back into the lift shaft and lift cabin free from contaminants and may permeate the entire enclosed volume of the elevator, thereby destroying bacteria and virus in the air and on the surfaces of the elevator, circulating clean air and cleaning any contaminated air incoming via opening of the elevator doors or from passengers coughing and sneezing, for example.
