摘要： A fluid filter arrangement includes a housing defining a slot arrangement. A filter cartridge is oriented within the housing. A projection arrangement engages the slot arrangement in the housing and spaces the filter cartridge from a wall of the housing to define a fluid flow path between the cartridge and the housing wall. A filter cartridge includes a tubular construction of filter media and a projection arrangement. A filter assembly includes the filter arrangement connected to a filter head. Preferably, the filter cartridge and filter head are made of plastic. Methods of assembling a filter includes inserting a filter cartridge and projection arrangement into an open end of a housing, engaging projections against through-slots defined by the housing to secure the filter cartridge in the housing. In some arrangements, a filter housing includes a plastic wall having an interior side with a support structure in the form of ribs extending from the interior side of the housing. In some arrangements, the plastic filter head is modular and may include male threads molded as part of the filter head.
