A filter cartridge is made from an elongate, rectangularly shaped, pleated filter element that is secured at opposite ends thereof in a pair of end caps. The cartridge is removably mounted in a filter housing sealingly to surround an elongate, perforated, square-shaped element that is fixed in the housing to have one end of its central opening connected through a central opening in one of the cartridge end caps, and through an outlet opening in the housing with apparatus that is operable to draw fluid into the housing and through the pleated filter element to the outlet opening.
