ABSTRACT:
The present invention provides a water purification cartridge with unidirectional fluid flow through the filter media. Preferably, the fluid flow is down through the media to prevent fluidization of the media which can have a negative effect on the capacity of the filter cartridge to filter fluid. A cartridge assembly includes a plurality of cartridge units. Each cartridge unit has a bottom cap and a top cap. Preferably, the top cap includes the inlet and outlet ports for each cartridge unit. The fluid flows into the cartridge, down the filter media to the lower end and a bottom cap collects the filtered fluid and directs the fluid to a tube which extends from the lower end of the cartridge to the upper end. The tube is rigidly mounted at the top of the cartridge and slidingly mounted on the bottom of the cartridge. Additionally, a novel method of making a filter cartridge is disclosed.
