Abstract
A replaceable water filter unit which can be used with a water pitcher, water bottle, or other such water dispensing device utilizes activated charcoal particles which are sandwiched between a pair of pads which may be fabricated of polyester felt batting material. The pads and charcoal particles sandwiched therebetween are installed in a frusto-conical housing with the pads in tight abutment against the side walls of the housing. The opposite end walls of the housing are apertured and each of the pads is installed directly opposite one of these end wall portions. The housing is removably installed in the outlet portion of the water dispensing device such that the water passes through the pads and the charcoal particles when being dispensed.
