A portable airborne pathogen control apparatus and system. Aspects of the present disclosure provide for a portable airborne pathogen control apparatus configured to be selectively positioned within an interior room and configured to enable a floor-to-ceiling flow of air within the interior room. The portable airborne pathogen control apparatus may comprise a housing with an air intake disposed at a lower area of a base housing and an air outlet disposed at an upper area of an elongated duct extending from the base housing. A blower fan housed within an interior chamber of the housing may be configured to direct a floor-to-ceiling flow of air through the interior chamber from the air intake to the air outlet. A volume of air directed through the interior chamber of the housing may be disinfected using one or more UV-C emitters and/or cold plasma generator(s) housing in the interior chamber of the housing.

A decontamination assembly, for pharmaceutical applications includes at least one chamber to be decontaminated (4) having a decontamination liquid storage tank (36) by which several atomizers (A, B, C. D) disposed in the chamber to be decontaminated (4) for producing a decontaminant aerosol can be supplied with decontamination liquid using valves (27) which can be controlled by electronic control, the atomizers (A, B, C, D) being in fluid communication with a ring conduit (32) having an inlet (33) and a separate outlet (34) by the valves (27), decontamination liquid from the decontamination liquid storage tank (36) being conveyable into the inlet of the ring conduit by a pump (35) and decontamination liquid flowing out of the outlet of the ring conduit back into the decontamination liquid storage tank (36), and a pressure adjustment mechanism (37) for keeping the pressure in the ring conduit (32) at a predefined liquid pressure range assigned to the ring conduit (32). A measuring mechanism (40) for determining a total volume of decontamination liquid dispensed to the atomizers (A, B, C, D) during a decontamination cycle includes a weighing mechanism (41) for determining a decontamination liquid volume in the decontamination liquid storage tank (36).

An air filtering and treatment apparatus (10), the apparatus (10) including: a housing (12) having an air inlet (14), an air outlet (16), an air passageway (24) between the inlet (14) and outlet (16), and a fan (18) arranged to urge air through the air passageway (24) between the air inlet (14) and the air outlet (16), wherein the housing (12) includes filter (20) arranged to filter air passing through the air passageway (24), and a receptacle (26) located toward the air outlet (16) relative to filter (20). The receptacle (26) is adapted to hold treatment composition (22) such that an evaporable vapour associated with the treatment composition (22) is able to accumulate in a headspace (41) of the receptacle (26), the headspace (41) including at least one aperture (36). The air passageway (24) may be shaped such that air flows substantially perpendicularly past the at least one aperture (36) of the receptacle (26) such that a pre-determined amount of the evaporable vapour is entrained into the filtered air released from the air outlet (16). A system (100) and method are also disclosed.

A combination air filter and goggles includes a pair of goggles; an air filter; a tube having a first end attached to the goggles and a second end attached to the air filter; a first strap having two ends attached to the air filter; and a check valve disposed on the goggles. The air filter includes a centrifugal fan, a circuit board, a UV lamp, a filter element, a power supply, a housing, and a cover. Clean air produced by the air filter may flow to inside of the goggles.

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.

An air cleaner is provided that may include a case including a first suction inlet, the case having a cylindrical or cone shape; a fan housing provided inside of the case, the fan housing accommodating a fan therein; a filter provided at a suction side of the fan, the filter filtering foreign materials in air which is suctioned through the first suction inlet; and a housing suction flow path formed between an outer surface of the fan housing and an inner surface of the case, the housing suction flow path allowing air which is suctioned through the first suction inlet to flow toward and through the filter. The housing suction flow path may include a first flow path inlet having a predetermined first width, and a second flow path inlet through which air having passed through the first flow path inlet flows, the second flow path inlet having a second width greater than the first width.
