A flow path is disclosed that comprises a suction part that suctions a fluid and a discharge part that discharges the fluid, the flow path being configured so that the path thereof is defined as non-linear and is set so as to be longer than the linear distance of the flow path; and a decreasing/eliminating means in which a subject contained in the fluid and flowing downstream in the flow path is subjected to decomposition and/or deactivation and/or sterilization.

The disclosure provides a device for purification, sterilization and deodorization of air. The device includes a housing, a sterilization and disinfection device, a fan, a deodorization device, and a photocatalyst reactor. The housing is in a barrel shape and includes a side wall including a plurality of air inlets. The fan is disposed on one end of the housing. The deodorization device, the photocatalyst reactor and the sterilization and disinfection device are disposed in the housing.

A portable, vortex driven ozone distributor is disclosed that includes a vortex van and multiple ozone generation units within a canister. The vortex fan in combination with the canister provides the ability generate a high velocity stream of ozonated air that may be directed against the ceiling of a room. The high velocity of the ozonated airstream permits all surfaces of the room to be sanitized by the ozone because the air traverses the ceiling and follows the walls down to contact all surfaces of the room.

Examples are disclosed that relate to recirculating ventilation systems for cooking appliances. One example provides a cooking appliance ventilation system, comprising a ventilation duct comprising an inlet aperture configured to receive cooking exhaust, a fan configured to pull the cooking exhaust through the inlet aperture and the ventilation duct, an ozone source configured to introduce ozone into the ventilation duct; and one more ozone mitigation components positioned within the ventilation duct downstream of the ozone source.

An apparatus and method for reducing scent emanating from a substantially enclosed structure such as a hunting blind. A fan in a fluid conduit draws odor-laden air from the internal environment and passes it through an ozone-rich vicinity provided for example by one or more ozone generators, then exhausts the treated deodorized air to the external environment. Fresh air is introduced into the negative-pressure enclosure from the external environment through one or more gaps or cervices in the structure.

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 built-in apparatus and method for treating air including a housing with an air inlet and an air outlet. An air mover positioned near the air outlet is configured to draw the air through the air inlet. The housing encloses an air treatment zone, such as including an oxidizing zone, and an ozone removal zone positioned downstream of the air treatment zone and oxidizing zone. The air treatment zone includes UV light and/or ozone that partially oxidizes the chemical contaminants in the air treatment zone. A catalyst in the oxidizing zone oxidizes elements within the air treatment zone. The ozone removal zone includes a second, different catalyst material. A UV bulb that may or may not generate ozone is positioned within or downstream of the first and/or second catalyst materials to assist catalyst oxidation and/or self-clean the apparatus.

The present technology relates to respirator devices including source control features. In some embodiments, a source control mask device can include a shield that substantially covers the mouth and nose of a user and a mechanism that can actively extract air as it is exhaled by the user. The extracted exhaled air can then be sanitized before the mask device discharges it into the atmosphere. The mask device may selectively form a seal to the user's face dependent on air flow conditions.

A drying machine, comprising a box body. A first partition plate is provided in the box body, and the first partition plate is located in front of a rear wall of the box body; a drying cavity and a first accommodation cavity are respectively located on two sides of the first partition plate; the first accommodation cavity is defined between the first partition plate and the rear wall; a fan wheel is provided in the first accommodation cavity, and a rotation axis of the fan wheel is perpendicular to the first partition plate and the rear wall; a first air inlet is formed in the first partition plate, a second air inlet is formed in the rear wall; the first air inlet and the second air inlet are respectively opposite to the axial direction of the fan wheel; the fan wheel realize the inner circulation and outer circulation of air.

A gas processing device includes: a casing that includes a first end having a first opening region constituting an intake port, a second end having a second opening region constituting an exhaust port, and a main body portion on the inside of which is formed a hollow portion; a discharge lamp that has a tube body which is disposed in the hollow portion and which has a shape extending in the first direction, a first electrode, and a second electrode, the discharge lamp that emits ultraviolet rays from the tube body; a power supply unit arranged outside the casing; and a first power supply line and a second power supply line that are wired so as to pass through a side closer to the first end than the main body portion, and that electrically connect the power supply unit to the first electrode and the second electrode.
