Abstract
A fluid filter having a frame and filter media supported by the frame through which a fluid to be treated is directed. The frame has at least first and second frame assemblies that are reconfigurable to place the filter selectively in: a) a first predetermined operative state; and b) a second predetermined operative state. The frame cooperates with the filter media so that the filter media: i) extends over a first intake area with the filter in the first predetermined operative state; and ii) extends over a second intake area that is different than the first intake area with the filter in the second predetermined operative state.
