Abstract
Apparatus for closing the front of an air purifying unit that includes a main support frame upon which is secured a rear cover and a top cover. A removable front cover is arranged to pass over the front section of the support frame and closes against the top and rear cover. A latching device acts between the support frame and the top cover to secure the cover to the frame. Biasing members are mounted upon the support frame for urging the walls of the front and rear covers outwardly and guiding the covers into edge to edge alignment.
