Abstract

An Air filtering device (1) configured to cleaning of air in a closed volume of air. (1) comprises in a direction (2) of an air flow at least one air filter unit (3). The air filter unit (3) comprises an air filter (5) arranged in a box-shaped housing (4). The air filtering device (1) further comprises an air moving unit (6) interconnected to and arranged downstream with respect to the air filter unit (3). The air moving unit (6) comprises a box-shaped housing (7) with an air inlet opening (8), configured to receive filtered air from the closed volume of air through the air filter unit (3) and with respect to the box-shaped housing (7) opposite an air outlet opening (9) comprising a constriction having a smaller diameter (10) than the diameter of the air inlet opening (8). The air moving unit (6) also comprises a fan (11) interconnected to the air outlet opening (9) configured to draw in the filtered air from the air filter unit into the box-shaped housing (7) through the air inlet opening (8) and to push the filtered air into an air distribution unit (12). The air distribution unit (12) comprising a box-shaped housing (13) interconnected to the fan (11) and having at least one air vent (14) to distribute the filtered air into the closed volume of air.
