Filtering water bottle

Abstract

A portable, personal apparatus for treating drinking water comprises a generally tubular or cylindrical filter housing containing filtration media and water-permeable screen or mesh or felt or membrane or netting layer at the top and bottom ends of the filter. The design of the apparatus involves the bottle exterior and interior contouring to the filter and enables the efficient and rapid gravity flow of water in through the filter. The apparatus may be configured such that water is first passed through a top reservoir designed to receive water, followed by a porous mesh, followed by granular filtration and antimicrobial media agitated by turbulent motion of influent water, followed by a porous mesh before reaching a durable and reusable water containment vessel.

We claim: 
     
         1 . A portable, personal apparatus for treating drinking water, comprising:
 a generally tubular or cylindrical filter housing having a filter containing filtration media that comprises a water-permeable screen or mesh or felt or membrane or netting layer at the top and bottom ends of the filter enabling gravity flow of water through the filter.
