The fluid purification device comprises a cylindrical filter member 12 made of porous plastic material. The filter member is tubular in construction and has an inner longitudinally extending channel 14. The outside surface of the filter member has a chemically treated fabricated nylon resin 30 adhered, or otherwise attached, thereto. The resin is chemically treated by, for example, bonding nylon beads with penta-iodide. Water, or another fluid, which passes through the resin is treated and purified by iodine leaking into the water. Other similar chemicals could be used instead of iodine such as chlorine. Any harmful compounds still in the water after it has passed through the resin are removed by the filter member as it passes into the inner channel. The purified water is safe to be drunk by humans. One end of the filter member 12 may be closed by a removable base member (16, Fig. 1). The base member has incorporated therein an umbrella valve. The base member has a central aperture 18 extending therethrough. The base member may have further apertures in the vicinity of the central aperture and a cap (20, Fig. 4) which has a plurality of small apertures (21, Fig. 4) which allow air to flow down the channel and out through the base member while preventing fluid to flow back thorough the base member into channel 14. In use, fluid contained with channel 14 can flow through outlet (28, Fig. 1) via a stem (24, Fig. 1). A lid portion (26, Fig. 1) may engage with the rim of an outer casing of a water bottle so that the filter member may be encased therein. The water can be accessed from the inner channel 14 by simply sucking on the outlet 28 of the stem 24.
