Filtering water bottle

摘要

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.

1. A portable, filter apparatus for treating drinking water, comprising:
a filter housing having a filter chamber containing granular filtration media that comprises granular activated carbon, the filter housing having a reservoir positioned upstream the filter chamber to provide a gravity flow of water through the filter chamber, a venting mesh positioned between a bottom end of the reservoir and a top end of the filter chamber, wherein the venting mesh has a top surface positioned adjacent the reservoir and a bottom surface that retains the granular filtration media within the filter chamber, and a filter pad positioned at a bottom end of the filter housing, wherein the filter pad has a top surface that is adjacent to the granular filtration media and a bottom surface, the filter pad retaining the granular filtration media within the filter chamber, the venting mesh having a porosity that is coarser than a porosity of the filter pad, and wherein said filter apparatus allows for a flow rate of about 0.5 Lpm to about 5 Lpm through the filter chamber when the reservoir is filled with water at atmospheric pressure.
