ABSTRACT:
A mobile air filtering apparatus for hospital rooms, comprises a housing having an inlet and an outlet. A pre-filter is located at the inlet and a fan for directing air in succession through a heater, a diffusion foil moistener and a mechanical filter. The diffusion foil moistener is located between the heater and the mechanical filter and it includes a heat exchange conduit for conducting the water to the moistener which is coiled around the filter. The filter housing is mounted on a fork-shaped arm which is carried on a stand in an adjustable position and the stand is moved around with its associated carriage filter. The diffusion foil comprises a double spirally wound tube having an inlet feeding in one spiral direction and an outlet feeding in an opposite spiral direction which is located alongside the inlet and which is held in position by spacers and bracings on a supporting plate which has air passage openings therethrough so that the air travels over the successive coil windings of the circulated liquid. The outlet of the device is covered by a removable diffuser.
