The present invention provides a gas generator comprising an electrolytic cell, a gas pathway, and an ozonator. The electrolytic cell is configured for electrolyzing the electrolyzed water to generate the gas with hydrogen. The gas generated from the electrolytic cell is transferred by the gas pathway for human to inhale. The ozonator is connected to the gas pathway for generating ozone to enter the gas pathway. The present invention uses the ozonator to generate ozone for cleaning the gas pathway, thereby providing a pure gas with hydrogen.

An automatic dispensing device for volatile fluid operable to apply one or more agent to a local environment for more than 14 days. Preferred devices dispense a first agent for air freshening, and may optionally dispense a second agent, such as a drain cleaner. A workable drain cleaner is structured to permit a slow release of drain cleaning agent. A dispensing device may nonexclusively operate by evaporation of volatile fluid from a polymer or rubber-like carrier material that is infused with the volatile fluid; gravity-induced drip from a bulk supply of volatile fluid through a small orifice onto an emanator; osmotic transfer of volatile fluid from a bulk supply; gas-pump drive of volatile fluid at controlled pressure; or diffusion of volatile fluid through a wall of a container of bulk volatile fluid; and combinations thereof.

A multifunctional microwave plasma and ultraviolet light deodorization treatment unit, which includes: a rapid decomposition device (1), a high frequency plasma electric field (2), a microwave plasma electric field (3), a high intensity ultraviolet radiation field (4), a low temperature plasma electric field (5), a high intensity ozone gas reaction chamber (6), a reaction termination chamber (7) and a clean gas organization chamber (8) sequentially installed inside a horizontal rectangular box which has an elongated body defining a horizontal axis and has a channel cavity therein. The deodorization treatment unit further includes an exhaust gas odor collecting pipe and an odor gas storage cabinet (9) connected to an air pump (10), the air pump (10) is connected to an odor gas inlet of the rapid decomposition device (1), the clean gas organization chamber (8) has one end connected to a clean gas exhaust pipe.

A portable microorganism sanitation system produces UV light and air treatment for treating an enclosed space, such as a room. A portable microorganism sanitation system incorporates a plurality of UV light sources configured around a lamp tower having reflective surfaces to produce emitted UV and reflected UV light in a wide range of angles. This wide range of angles of the emitted and reflected UV light enables more complete and direct impingement of UV light on surfaces in the enclosure or room. The portable microorganism sanitation system also incorporates active air treatment, wherein an air moving device draws airflow into a conduit inside of the lamp tower and then through airflow outlets. The airflow outlets are configured to expose the outlet airflow to the UV light sources, thereby treating the airflow to destroy microorganism therein. Photocatalyst may be configured on the surfaces of the lamp tower to promote microorganism destruction.

Described herein are systems and methods for treatment of various airborne or surface-associated contaminants in which UV aerosol technology is combined with the use of hydrogen peroxide vapor or aerosol to create potent airborne concentrations of reactive oxygen-containing radicals that react with the airborne or surface-associated contaminants to inactivate, disinfect, oxidize, rearrange, ablate and/or otherwise treat these materials and thereby achieve disinfection of indoor air and/or surfaces. This technology is referred to herein as peroxide-enhanced germicidal irradiation (PEGI).

Embodiments relate to a plasma generator including a dielectric layer elongated in a longitudinal direction that extends 0.01 mm-2 mm in a thickness direction perpendicular to the longitudinal direction. The dielectric layer defines first and second planar surfaces that are separated in the thickness direction. A first electrode is disposed along a first portion of the first planar surface. A second electrode is disposed along a second portion of the second planar surface, such that at least a part of the first and second portions are separated in the longitudinal direction of the dielectric layer. A power supply is configured to supply electrical power to the first and second electrodes at a predetermined voltage and frequency, wherein plasma is generated adjacent each of the first and second electrodes and along the first and second surfaces of the dielectric layer other than the first and second portions.

A cover assembly is configured for disinfecting an air conditioning unit. The assembly includes a cover made of a pliable material that is shaped to be installed on the inside portion of an air conditioning unit. The assembly also includes an ozone generator configured to direct ozone into the air conditioning unit. A controller is operatively coupled to the ozone generator and is configured to control operation of the ozone generator.

The vehicle interior deodorizer may comprise a deodorizing device for deodorizing the interior of a vehicle and a method of using the deodorizing device. During a treatment cycle, the deodorizing device may release a chemical tablet into a cup holding water after an evacuation interval. The chemical tablet may dissolve in the water, creating a deodorizing solution. A bubbler mechanism may de-gas the deodorizing solution and may force deodorizing gas out of the deodorizing device such that the deodorizing gas may saturate the interior of the vehicle during a treatment interval. The bubbler mechanism may quiesce during a dissipation interval such that the deodorizing gas may abate. The vehicle may be opened and aired out to complete the treatment cycle.

A decontamination system for sterilizing a contaminated space, comprising at least one decontamination unit through which the air of the contaminated space is recirculated, which unit comprises an inlet arrangement for introducing air from the contaminated space into the unit, a discharge arrangement for discharging gas out of the unit, a fan for creating an air flow from the inlet arrangement to the discharging arrangement, H.sub.2O.sub.2 supply device for introducing H.sub.2O.sub.2 into the air flow inside the unit, where the decontamination unit comprises at least one of the discharge arrangement comprises detachable at least one outlet module through which the H.sub.2O.sub.2-air mixture is discharged out of the unit, or the inlet arrangement comprises at least one detachable inlet module for receiving air from a space into the unit.
