ABSTRACT:
A faucet-mounted filter in which a housing is positioned in flow transmitting relation with the water flow line. A microporous, hollow fiber filter bundle is positioned to sealingly occlude water flow through the housing so that all water flow through the housing must pass through porous walls of the hollow fibers of the filter. The pores of the hollow fiber walls are no larger than 0.22 micron, as measured by the particles that the pores pass. Thus the filter is capable of microbial filtering.
