A sanitization device may include a sanitization compartment including an ozone outlet, a connector defining a fluid pathway that is fluidly coupled to the sanitization compartment, an ozone operating system having an ozone generator configured to generate ozone and a distribution fan configured to urge ozone generated by the ozone generator through the fluid pathway of the connector and into the sanitization compartment, a filter access door transitionable between an open position and a closed position, the filter access door including a filter holder configured to receive a filter such that the filter fluidly couples to the ozone outlet when the filter access door is in the closed position, the filter is configured to reduce ozone passing therethrough to oxygen and the filter is downstream of the connector, and an exhaust fan fluidly coupled to the ozone outlet and configured to urge ozone through the filter.

Provided are a catalyst structure for ozone decomposition including a support containing a porous inorganic material, and an -MnO.sub.2 catalyst located on at least a portion of inner pores and a surface of the support, an air-cleaning method using the same, and an air-cleaning device and an air-cleaning system each including the catalyst structure for ozone decomposition.

A sterilization, disinfection, sanitization, or decontamination system having a chamber defining a region, and a generator for creating a free radical effluent with reactive oxygen, nitrogen, and other species and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The system is used in sterilizing, disinfecting, sanitizing, or decontaminating items in the chamber or room and, with a wound chamber, in treating wounds on a body. The wound chamber may be designed to maintain separation from wounds being treated. Various embodiments can control moisture to reduce or avoid unwanted condensation. Some embodiments can be incorporated into an appliance having a closed space, such as a washing machine. Some embodiments may include a residual coating device that deposits a bactericidal coating on sterilized items.

Systems and methods for sterilizing an enclosed space using ozone are disclosed herein. Various embodiments of the devices and methods also provide for accelerated degradation of the ozone upon sterilization. The methods can include identifying enclosed spaces, sterilizing enclosed spaces through ozone generation, generating reports and transmitting the reports. The sterilization unit disclosed herein can sterilize a plurality of enclosed spaces, such as a fleet of medical response vehicles.

An anti-bacterial photocatalytic coating apparatus includes a chassis and a container containing an anti-bacterial photocatalytic coating liquid. There is a means mounted on the chassis for applying plasma-based surface activation unto a stationary surface underneath the chassis. There is also a means mounted on the chassis for spraying the anti-bacterial photocatalytic coating liquid on the surface underneath the chassis. A third means mounted on the chassis for shining UV light onto the surface sprayed with the anti-bacterial photocatalytic coating liquid. Optionally, there is a means mounted on the chassis for baking the surface sprayed with the anti-bacterial photocatalytic coating liquid. The plasma-based surface activation may be replaced with the spraying of a non-photocatalytic prime coating. The equivalent anti-bacterial photocatalytic coating processes for coating stationary surface are also introduced.

A cabinet provides a continuous sanitizing environment for items contained within the cabinet. The sanitizing environment is achieved by generated oxygen, ozone, and ultraviolet light within the cabinet. Expelled oxygen and ozone from the cabinet sanitize the ambient environment in which cabinet resides in.

A bacteria treatment mechanism and a bacteria treatment method capable of reliably sterilizing an exterior of an article are provided.

A bacteria treatment mechanism includes: a bacteria treatment unit that has a space for performing bacteria treatment; a radiation irradiation unit that irradiates the bacteria treatment unit with radiation for performing the bacteria treatment; an air supply duct that supplies air to the bacteria treatment unit; a decontamination treatment fluid supply unit that supplies a decontamination treatment fluid to the air supply duct during initial decontamination of the air supply duct; and an exhaust duct that exhausts molecules in the bacteria treatment unit.

[Problem] To provide a deodorizer that supplies ozone-containing gas to a spot to be deodorized and deodorizes same and that can break down and remove odoriferous substances existing inside an object to be deodorized such as a textile product.

[Solution] Provided is a deodorizer which includes a deodorizing bed that can be pressed against a spot to be deodorized, and is characterized in that the deodorizing bed has: a first room which has an air supply port to supply ozone-containing gas to the spot to be deodorized; a second room which is provided adjacent to the first room and has an exhaust port that suctions the gas supplied to the spot to be deodorized; and a partition that separates the first room from the second room.

An ionic oxidation refreshing system for refreshing odorized items, comprising an enclosure to contact the odorized items; an ionizing stage mechanism that produces an ionized ozone gas mixture inside of the enclosure, killing germs, including odor-causing bacteria, viruses, molds, and fungus; and a filtering stage mechanism that neutralizes and filters out any toxic by-products including one or more of ozone, nitric acid, aldehydes, and VOCs resulting from surface oxidation of the odorized items by the ionized ozone gas mixture.

A medical probe disinfecting and sterilizing system for disinfecting and/or sterilizing medical devices may include a chamber for cleaning the probe by exposure to ultraviolet light and to a misted disinfectant chemical. The disinfectant may be misted by one or more ultrasonic transducers.
