ABSTRACT:
A high-efficiency air filtering apparatus for cleaning and circulating air in a closed room is in the shape of a vertical cylinder and includes a semi-cylindrical housing and a semi-cylindrical filtering chamber, both enclosing a centrifugal blower configured to suck filtered air out of the apparatus through the filter and to blow it into the room. The apparatus is characterized by that the filtering chamber contains a closely pleated filter sheet of HEPA-filter which is covered on top and bottom by flat panels and is air-tightly pressed onto the semi-cylindrical housing, thus making the apparatus completely air tight. The filtering chamber is urged onto the contour of the filtering chamber and is releasably fastened to the top and bottom of the housing, permitting replacement of the filter after clogging. A pressure sensor is mounted on the blower housing configured to effect a visible signal to be issued as soon as the pressure inside the housing rises above a predesignated magnitude due to clogging of the filter.
