Abstract
A lifting device for a portable air purifying unit that includes a rectangular main support member for supporting all the component parts of the unit so that they are balanced about the support. A housing comprising a top cover and front and rear covers is attached to the support for enclosing the unit. The top cover is coextensive with the top wall of the support and contains a raised partition that extends laterally across the cover. A hand-hold passes through the center of the partition that opens into an enclosure mounted on the cover in front of the partition. The hand-hold and the chamber combine to form a handle. The front cover of the housing passes over the handle to partially shield the handle thereunder.
