adhesive a snap fit or by being formed as a single piece with the ribs the fulcrum ring may be made out of any noncorrosive structurally nondeformable material such as a structural plastic or nylon fig3 and 4 are planar views taken through the upper portion 14 which further show the structural interrelationships within the upper portion the lower portion 16 has a resilient wall 20 39 which is integral with the resilient wall 20 of the upper portion 14 within the resilient wall 20 39 there is located a filtration system 34 and the base 18 for regulating water flow through and out of the portable tap water filter 10 the filtration system 34 is of a conventional state of the art type which is intended to remove solid debris as well as other undesirable contaminants from the water flowing therethrough by way of example and not by limitation the filtration system shown in fig2 includes the following componets in sequential order from the upper portion 14 a screen mesh 36 for removing solid debris three layers for contaminant removal including an activated charcoal cloth layer 38 a sand layer 40 and a cloth filter layer 42 and finally a baffle 44 made preferably of plastic for ensuring even water flow through the filter layers the base 18 includes a saucer 46 located at the axial center of the lower portion 16 as well as a plurality of drill holes 48 which are annularly arranged around the periphery of the saucer and within the resilient wall 20 39 the filtration system 34 is held in place within the lower portion 16 by nibs 50 and by any conventional fastening means at the base 18 such as a nontoxic adhesive.
