摘要： A microbial ventilation device has a cone-shaped coandella and an air blower assembly. The air blower assembly includes a housing has a first end, a second end, and an air flow passage extending between the first and second ends. The air blower assembly further has an electric fan configured to draw air into the air flow passage through the first end and discharged the air from the air flow passage through the second end. The housing is disposed in relation to a bottom surface of the coandella such that the second end is spaced a distance from the bottom surface so that air discharged from the air flow passage impinges upon the bottom surface and is caused to flow along the bottom surface in a radial outward direction and then beyond a peripheral edge of the coandella creating an air dome of radially out flowing air.

摘要： An energy-transmissible air filtration system having at least one mechanical filter and at least one electromagnetic energy source. The electromagnetic energy source generates an electromagnetic energy wave or force that traverses the at least one mechanical filter. This results in substantially simultaneous mechanical filtration and energy-based decontamination of an airstream. Other features of the embodiments are also shown.

摘要： A system for mitigating airborne pathogens from a livestock house is disclosed. In an embodiment, there is disclosed a cross-flow ventilation system, which is fluidly connected to a livestock house and configured to control the air quality and movement by introducing ambient air into at least one air filtration system that is attached to a side wall of the house; conditioning the air in the air filtration system by performing at least one step selected from filtering, cooling, disinfecting, or pressurizing the air; introducing the conditioned air into an air chamber; flowing the conditioned air from the air chamber into the house through at least one ventilation panel to the opposing sidewall with a laminar or substantially laminal flow of air; and removing the air from the house using an exhaust fan attached to a side wall opposite the side wall containing the air filtration system.

摘要： An indoor pollution prevention system includes a plurality of gas detection modules, one or more intelligent control-driving processing devices, one or more gas-exchange processing devices, one or more intake passages, and one or more discharge passages. The intake passage is connected to the gas-exchange processing device and has an intake opening for guiding the outdoor gas into an indoor space. The discharge passage is connected to the gas-exchange processing device and has a discharge opening for discharging the air pollution source to the outdoor space. The intelligent control-driving processing device controls the gas-exchange processing device to be enabled under a surveillance condition of the gas detection module, so that the air pollution source passes through the discharge passage, filtered and purified by a cleaning and filtration assembly, and is discharged to the outdoor space, thereby allowing the indoor space to have a clean air.

摘要： An air sterilization system utilizing three stages of sterilization using UVC and microwave energy created by one or more magnetrons powered by solid state high voltage supplies. The first stage is formed by a chamber with concentrated 265 nm UVC generated by two rings of UVC leds, the second stage formed by a chamber with a labyrinth to allow maximum exposure of the air by microwaves generated by 2 magnetrons, the third stage is formed with concentrated 265 nm UVC generated by two rings of UVC leds. There are also HEPA filters at both the inlet and outlet of the unit. The unit can be configured to be free standing without specialized installation required or can be hardwired into a circuit. Only the stand-alone unit incorporates a telescoping inlet to the height to be adjusted up to 12 feet.

摘要： The present invention relates to an HVAC system scented air filter. The scented air filter is configured to secure to an HVAC vent or along the ductwork connected thereto. The air filter includes a pair of air filters for filtering air and a scented layer removably disposed between the pair of air filters. The scented layer can be infused with fragrance and includes a plurality of evaporating fragrance gel discs for dispensing fragrance through the filter. The air filter provides a reminder system, or useful/active life indicator, to notify an owner to change the filter when the fragrance is diminished. The filter can provide an electronic nose sensor to detect fragrance in blowing air or a timer button can provide a reminder to the user to replace the filter. Alternatively, a QR code can be used for reminding the user to replace the filter.

摘要： The Desktop Air Purifier with Double-layer Glass Tube Ultraviolet Disinfection Lamp (The desktop air purifier with DLGTUVDL) uses a turbo blower with an air filter to draw in outside air to be disinfected through its specially designed double-layer glass tube ultraviolet disinfection lamp.
The ultraviolet disinfection lamp of the desktop air purifier has a double-layer glass tube with an inner glass tube and an outer glass tube. The center of the inner glass tube is a hollow space for external air to pass through and receive UV disinfection. This unique design allows ultraviolet rays to surround the entire hollow tube space to provide 360-degree ultraviolet radiation and disinfection at a close distance without dead ends, which greatly improves the disinfection efficiency.
In addition, the desktop air purifier with DLGTUVDL has the function of natural plant scent air purifying agent to provide the disinfected air that carries the natural plant scents.
