Abstract: In accordance with one aspect of the present exemplary embodiment, a portable air filter cleaning device is provided. The device comprises a support frame including at least two legs and a rotatable air filter receiving frame defining a perimeter. The rotatable air filter receiving frame is supported by the support frame. A tube having a first end adapted to receive a water line and a second end including a plurality of outlets is also provided. The second end of the tube is oriented to direct water from the outlets toward the air filter receiving frame perimeter so that water ejected from the outlets impacts a washable air filter mounted upon the air filter receiving frame and causes rotation thereof.
