ABSTRACT:
An air circulator and air filtration device for a room or other enclosed space supported in the corner thereof intermediate the floor and ceiling and including an upwardly opening top air inlet and a downwardly opening bottom air inlet with each inlet including a filter assembly and a pair of discharge outlets for discharging air horizontally in a path generally parallel to and adjacent the walls which intersect to form the corner in which the air circulator is mounted. The air circulator includes a single motor and an upper and lower blower assembly driven by the motor with the upper blower assembly communicating only with the upper air inlet and discharging toward one of the air outlets and the lower blower assembly communicating only with the bottom inlet and discharging toward the other of the outlets for maintaining a substantially constant and equal volume of air discharged along each of the intersecting walls of the room for effective circulation of air throughout the room and substantially eliminating temperature stratification in the room. Each air inlet filter assembly includes a foam pre-filter and an activated carbon filter for cleaning and purifying air being circulated.
