A portable air filtration apparatus capable of rapid and efficient room air turnover and recirculation of filtered and decontaminated air with eradication of both microorganisms and biological agents. The invention relates to a compact device that can be used in ultra-clean air purification using a multi stage electrostatic precipitation and air filtration with disinfection and eradication of both microorganisms and biological agents by the application of ultraviolet light radiation. It can be used in any application where space, lower cost or ultra-fine particulate filtering is needed; such as in clean rooms and surgical suites. The device is extremely efficient for purifying contaminated air from entrained dust and organic substances without using chemicals and physical filters, and it is hygienic and fireproof. The device including its multi stage electrostatic precipitator with the filter, connecting, releasing tubes and the fan is easy to clean and can be portable.

An air purification system for use in a given location to remove or destroy harmful pathogens in the air. The air purification system has a housing with an inlet, an outlet, and a passageway extending between the inlet and the outlet. An intense field generator and filter is used to charge any particles in the air and remove them from the air flow. Finally, a dielectric barrier discharge unit having a high voltage electrode coupled to a dielectric barrier and a ground electrode spaced apart from the high voltage electrode is used to form a low temperature plasma chamber is in communication with the passageway so that the ions created in the plasma chamber will attach to and destroy any remaining particles in the air flow.

Embodiments disclosed herein relate to air flow control blinds or tents useful for controlling scents emitted therefrom. The air flow control blinds include one or more walls, a roof, windows in the one or more walls, and at least one directional vent disposed on the one or more walls, where the at least one directional vent includes an inlet on the inner surface of the blind and an outlet fluidly connected to the inlet, the outlet facing downward on the outer surface of the blind to direct fluids flowing therethrough towards the ground. The air flow control blinds may include one or more roof vents adjacent to the one or more walls on the roof to remove air from an interior of the blind therethrough. The air flow control blind includes at least one oxidant generator mount on one or more of the roof or the one or more walls to mount an oxidant generator thereon. Blind systems include a portable oxidant generator positioned in the blind. The blinds and blind systems are used to control scents therein or therearound.

A ventilation unit is for ventilating an indoor space, and incorporates an air cleaning device and mechanical restrictor for controlling a restriction to a flow resulting from a pressure differential across the unit. There is determination of the inside and outside air pressures in the vicinity of the unit and of air quality parameters inside and outside. The air cleaning device and the mechanical restrictor are controlled in dependence on the determined air pressures and air quality parameters. This provides a fan-less, and hence low-power ventilation unit, which relies on throttling the natural air flow across the unit to provide flow control, and hence enable control of air quality. The air cleaning device may be operated only when the flow is into the inside space, saving power.
