A filter cleaning device for cleaning filters of porous material employed as air cleaners includes a pressure tank adapted to contain gaseous fluid under pressure and a flow conduit communicating with the tank and extending therefrom and having a baffle or shield mounted on the flow conduit and sized and shaped to engage the filter to be cleaned whereby the fluid under pressure is directed into an interior chamber of a filter upon actuating a control of the fluid thereby permitting flow of fluid under pressure from the tank into the filter to be cleaned and discharge of said fluid through the filter material in a direction opposite to the flow of air therethrough in normal operation of the filter.
