Abstract
A water filtering and purifying apparatus made according to the present invention comprises a water filtering and purifying apparatus for filtering and purifying water as it is ejected from a container at low gauge pressures generated by manually squeezing the container. The water filtering apparatus includes a cover for attaching to the container wherein the cover has a pressure responsive venting system for allowing air into the container while substantially preventing air and water contained in the container from escaping. A water filtration and purifying system is contained within the container and the filtration and purifying system comprises a replaceable pleated filter connected to a purifying cartridge.
Claims17
A water filtering apparatus comprising:
- a walled container having an interior and an exterior surface and a pressure responsive venting means for allowing air into the container while substantially preventing fluids contained in the container from escaping therefrom;
- supply means for allowing the container to be filled with water;
- a water filtration system contained within the container having a pleated filter portion and a filtration cartridge connected thereto;
- and
- an outlet tube connected to the filtration system and extending from the container to a point outside the container adjacent the exterior surface of the container, wherein the outlet tube contains a flow restricting device, the flow restricting device and the venting means sized to cause a predetermined back-wash through the filtration system when air enters the container.
A water filtering apparatus for filtering water at low pressures generated by manually squeezing a container, the apparatus comprising:
- a flexibly resilient walled container having an open end;
- a removable cover for covering the open end of the container wherein the cover has a pressure responsive venting means for allowing air into the container while substantially preventing fluids contained in the container from escaping therefrom;
- a water filtration system contained within the container, the filtration system comprising a replaceable pleated filter and a purification cartridge connected to the pleated filter;
- and
- an outlet tube, the outlet tube being connected to the filtration system and extending through the cover to a point outside the container, the outlet tube containing a flow restricting device, the flow restricting device and the venting means sized to cause a predetermined back-wash through the filtration system when air enters the container.
A water filtering apparatus for filtering water at low pressures generated by manually squeezing a container, the apparatus comprising:
- a flexibly resilient walled container having an open end;
- a removable cover for covering the open end of the container wherein the cover has a pressure responsive venting means for allowing air into the container while substantially preventing fluids contained in the container from escaping therefrom;
- a water filtration system contained within the container, the filtration system comprising:
- a replaceable pleated filter;
- a purification resin stage in fluid communication with and adjacent to the pleated filter;
- a carbon filter stage adjacent to and in fluid communication with the purification resin stage;
- and
- a plurality of separator means for separating the purification resin stage from the pleated filter and for separating the carbon filter stage from the purification stage;
- an outlet tube, the outlet tube connected to the filtration system and extending through the cover to a point outside the container;
- and
- a flow restricting device positioned within the outlet tube, the flow restricting device and the venting means sized to create a predetermined back-wash through the filtration system when air enters the container.
