ABSTRACT:
A filtration assembly useful in a household water-chilling system and having a filter with concentric cylindrical activated-charcoal elements supported between inner and outer porous plastic tubes. The filter is contained in a housing having a cover with radiused inlet and outlet ports. A coupling or adapter block having captive O-rings seals mates with the cover ports to conduct water through the filter. The block and cover are self aligning, and are positioned so no vertical clearance space is required to separate the filtration assembly from the block when the filter is serviced.
