An air purification unit and/or system for an environment with multiple seated individuals, including an air collector and air purification chamber, to be used independently from or in conjunction with the environment's air handling system.

An apparatus may include one or more light components that are configured to emit light to sanitize and disinfect one or more objects included within the apparatus. The apparatus may have an interior cavity at which the light components are located, where the interior cavity is accessible via one or more doors, an opening, a lid, etc. The apparatus may have a conveyor that transports objects from a first end of the apparatus to a second end of the apparatus, where the objects are sanitized during transport. The apparatus may be transitioned from an expanded configuration to an unexpanded/collapsed configuration, and vice versa. The apparatus may be stationary or include wheels or other mechanisms that allow the apparatus to be moved between different locations. Objects that are sanitized by the light components of the apparatus will be free of pathogens (e.g., viruses, bacteria, etc.) that are potentially harmful to humans.

An air treatment system comprising: an air purification assembly comprising one or more air purification modules and configured to, in an upstream to downstream order, take in air, produce purified air by conveying the air to traverse the one or more air purification modules, and expel the purified air; and an aerosol source configured to release a conditioning liquid in aerosol form into the purified air. Optionally, the conditioning liquid comprises a predetermined concentration of nonpathogenic micro-organisms. Optionally, one or more air purification modules comprises, in an upstream to downstream order, a HEPA or ULPA filter, a UVC irradiation unit, and an activated carbon filter.

One embodiment of the present invention provides a water circulation-type malodor reduction system including a fluid supply line that supplies a fluid to a roof of a livestock barn, a first reservoir which is provided on one side of the roof and in which the fluid flowing along the roof is accommodated, and an accommodation part in which the fluid falling from the first reservoir is accommodated, wherein the accommodation part is disposed so that the fluid falls in an S shape.

A virus removal device providing a high virus removal probability, a small pressure loss of a flowing gas, and miniaturization with respect to an amount of air to be treated, by adopting a wet mechanism for removing a virus from a gas, the virus removal device includes a cylindrical treatment room to introduce a gas and remove a virus, a catcher formed of a rotary brush, installed in the treatment room and configured to collect the virus contained in the gas, a liquid spraying mechanism in the treatment room, a rotary driving mechanism to rotate the catcher, a gas introducing portion to introduce the gas to the treatment room, a gas discharging portion to discharge the gas from which the virus has been removed from the treatment room, and a liquid discharging portion to discharge a liquid containing the virus that has been removed from the gas.

A method for extracting and capturing airborne aerosol and particulate matters in the air that may be potentially contaminated with harmful bacteria and viruses using a vacuum extraction system; treating the contaminated air by scrubbing it with a biocide solution; filtering the scrubbed air using activated carbon and HEPA filters to remove any residual biocide; and optionally, treating the filtered air with UV-C, ozone, or plasma, before the sterilized air is return to the environment.

An isolation section assembly includes a section housing defining an interior space. The section housing includes a door with access to the interior space. The isolation section assembly includes an enclosure abutting the door. The airlock enclosure defines an interior airlock space. The interior airlock space is configured and adapted to be at a negative pressure relative to a cabin area. An air recirculation system in fluid communication with at least one of the interior space of the section housing or the interior airlock space.

A whole-body or whole-room voluminous antiviral and antibacterial airborne disinfection system is disclosed which includes a sterilization chamber, including a nozzle disposed in the sterilization chamber, a tank disposed outside the sterilization chamber, the tank is adapted to hold a photosensitizer fluid of edible food dyes, a light source within the sterilization chamber adapted to flood the sterilization chamber with light; and a nozzle adapted to release the photosensitizer fluid aerosols and generate reactive oxygen species in a fog-like dispersion.

A purification device of exercise environment is provided and includes a main body, a purification unit, a gas guider and a gas detection module. The main body has at least one gas inlet and at least one gas outlet. The purification unit, the gas guider and the gas detection module are disposed in the main body. The purification unit filters a gas in an exercise environment introduced through the at least one gas inlet. The gas guider operates continuously to transport the gas in the exercise environment to be introduced through the at least one gas inlet and to flow through the purification unit. The gas detection module detects a gas information and a particulate cleanliness of the air in the exercise environment, and the particulate cleanliness of the gas in the breathing region around the nose of the exerciser reaches 0˜20 μg/m.sup.3 accordingly.

The present invention provides a safer way to intubate patients having communicable diseases, such as bacterial and viral infections. It protects health care professionals performing the intubation from bodily fluids of the patients that might otherwise be projected directly onto them by coughing, gagging, vomiting, or sneezing. Additionally, it traps airborne suspensions or aerosols containing pathogens, such as bacterial, myco-bacterial, viral, or fungal infections, originating from the patient and keeps them from entering into the air in close proximity to the healthcare professionals. The contaminated air can then be vented to a location which is away from personnel, such as an outdoor containment area. In one embodiment of this invention the contaminated air is passed through a disinfecting solution which destroys the pathogens before the air is recycled into the environment, such as the room where the intubation is carried out.
