<p>An orally usable filter straw (10) for the purification of water by forced movement of the water through the straw (10). The straw (10) includes an elongated tubular conduit (12) having an inlet (14) for reception of the water at a distal end (16) of the conduit (12) and having an outlet (16) at a proximal end (20) of the conduit (12) for expulsion of the treated water. Beginning at the inlet (14) of the straw (10), the straw (10) includes the following materials retained within the conduit (12): a removably mounted filter (26), a purification resin (46), activated carbon granules (52), and a bactericide resin (58). A mouthpiece (62) is mounted at the outlet (18) of the conduit (12) to allow the device to be suitably received by a human user. The straw (10) includes a series of porous spacers (44, 48, 56, 60) positioned within the conduit (12) to segregate the materials retained within the straw (10).</p> |
