    摘要： A filter cartridge has a shell defining an upper portion with an upper interior volume and a lower portion with a lower interior volume. The cartridge is for use in gravity-fed water treatment systems having an upper untreated supply and a lower filtered container. A hydrophilic porous particulate carbon powder block filter in a polymeric binder is disposed in the cartridge. The filter has a central opening and is open on both ends. The top end of the block is fitted with an air vent tube. The lower end of the block is fitted into a rubber gasket to direct water flow into the lower container. As water flows through the filter cartridge, air is vented through the block filter central opening and out through the vent tube.

    摘要： A universal water purifier unitary assembly device comprising a device housing unit support structure, a manually operated air pump, a force-fed water filter cartridge of multiple separable stages and a separable sealing means to seal the junction and opening between said universal water purifier unitary assembly device housing unit support structure and water container of water to be filtered wherein junction and opening between of said water purifier unitary assembly device housing unit support structure and said water container is sealed to retain compressed air. Water of said container is filtered, treated and used as needed on demand as in a group environment wherein individual use and consumption of purified water is relevant. The water is stored in a container, being pumped from the container by compressed air provided by an air pump. Filter elements include sediment and cyst removal filters, ion exchange resins, semi-permeable membranes including a hollow fiber membrane, porous activated carbon particles and activated carbon blocks. The device housing unit support structure unifies the functional elements of the invention as an operational unit of easy transport for use with any water container of a suitably sized mouth.

    摘要： A multi-stage water purification device includes an untreated water compartment having an untreated water inlet and a treated water compartment formed from a resilient material. The compartments are segregated from one another. An outlet is in flow communication with the treated water compartment. A first unidirectional valve is disposed between the treated water compartment and the outlet and is configure to permit flow out of the treated water compartment only. A filter is disposed between the untreated water compartment and the treated water compartment. The untreated water flows through the filter to produce treated water. A second unidirectional flow valve is positioned at the discharge of the filter and is configured to permit flow out of the filter and into the treated water compartment only. Water is introduced into the untreated water compartment and the treated water compartment is deformed to reduce the volume therein. As the treated water compartment returns to its initial volume it provides a negative pressure to draw the water through the filter into the treated water compartment.
