Provided is a filtration device that can increase a filtration treatment amount by suppressing clogging of a filtration filter. A filtration device according to the present invention includes: a filtration filter that includes a filter that filters a filtration target contained in a fluid, and a frame that holds the filter; a support structure that holds the frame such that the filter is bent; and a fluid supplying unit that supplies the fluid with the filter being in a bent state.

A cleanable filtration system for an air conditioning system includes a continuous filter positionable adjacent to an inlet opening in the air conditioning system and a drive system operably coupled to the continuous filter to move the continuous filter relative to the inlet opening. A cleaning jet is positioned to spray a cleaning fluid on an adjacent portion of the continuous filter.

An air conditioner unit includes a blower fan, an inlet grille upstream of the blower fan, and an outlet grille downstream of the blower fan. The air conditioner unit also includes an air filter positioned between the inlet grille and the outlet grille with a belt encircling and enclosing the air filter on four sides. The air conditioner unit further includes a motor operatively connected to the belt. The motor is configured to rotate the belt around the air filter and thereby clean the air filter.
