Water filter device

1. A water filter device comprising:

a replaceable mouthpiece comprising a lip contour having suction functionality and a threaded surface on the interior of the mouthpiece to engage one or more threads of a chamber;

a liquid tight lid removably connected to the mouthpiece;

the chamber having one or more threads threadably engaged with one or more threads on a bottle, the chamber being removably sealed within the bottle and having one or more side wall openings to allow liquid flow passage from the bottle into the chamber;

a filter cartridge sealed within the chamber, the filter cartridge having:

a solid side wall cylindrical in shape composed of solid materials;

a permeable layer positioned at the distal end of the filter cartridge;

a porous outlet positioned at the proximal end of the filter cartridge; and

a macrofilter, a microfilter, and a flavoring filter positioned inline between the permeable layer and the porous outlet and within the solid side wall cylindrical in shape;

wherein liquid flows linearly from the chamber through the permeable layer and through the inline filters of the filter cartridge in response to suction received at the mouthpiece.

2. The water filter device of claim 1 wherein said chamber comprises a concentric tube.

3. The water filter device of claim 1 wherein said macrofilter comprises a polymeric membrane having a pore diameter of 25 to 500 micrometers that is capable of removing particulates and sediment of about 50 micrometers.

4. The water filter device of claim 1 wherein said microfilter comprises activated carbon material.

5. The water filter device of claim 1 wherein said filter cartridge includes flavor pellets to impart taste to said filtered water.

6. The water filter device of claim 1 further comprising a lid that snaps on to said mouthpiece.

7. The water filter device of claim 1 wherein said filter cartridge is operable at an angle of 0 to 90 degrees from a horizontal position.

8. A method for filtering water comprising:

providing a water filter device secured to a container with water including:

a chamber having a first communication configured to receive water into said chamber from a bottle through one or more side wall openings;

a filter cartridge sealed within said chamber, said filter cartridge having a solid side wall cylindrical in shape composed of solid materials and a permeable layer positioned at the distal end of the filter cartridge, the permeable layer configured to receive water from said chamber and let water pass through a macrofilter and a microfilter positioned inline between said permeable layer and a porous outlet of said filter cartridge; and

a mouthpiece having a lip contour threadably engaged with said chamber, wherein said mouthpiece comprises a second communication configured to permit passage of water out of said filter cartridge;

in response to suction placed externally on said water filter device through said second communication of said mouthpiece, passing said water through said first communication of said chamber, then through said filter cartridge to remove sediment, chemicals, and heavy metals that may be present in said water.

9. The method of claim 8 wherein said water filter device secured to said container is operable at an angle of 0 to 90 degrees from a horizontal position.

10. A portable water filter device comprising:

a chamber having a first thread configured to engage a bottle and a second thread configured to engage a replaceable mouthpiece having a lip contour, the chamber including an inlet communication on a side wall of the chamber configured to receive external water from the bottle;

a filter cartridge sealed within said chamber, said filter cartridge comprising a permeable layer positioned on a distal end of the filter cartridge, a macrofilter, a microfilter, and a porous outlet positioned on a proximal end of the filter cartridge, to filter water passing through said filter cartridge; and

said replaceable mouthpiece sealed to said chamber, said replaceable mouthpiece configured to, in response to receiving suction force, causing passage of water through said filter cartridge and out of said replaceable mouthpiece;

wherein the macrofilter and the microfilter are positioned in-line between the permeable layer and the porous outlet.

11. The water filter device of claim 10 wherein said chamber comprises a concentric tube.

12. The water filter device of claim 10 wherein said macrofilter comprises a polymeric membrane having a pore diameter of 25 to 500 micrometers that is capable of removing particulates and sediment of about 50 micrometers.

13. The water filter device of claim 10 wherein said microfilter comprises activated carbon material.

14. The water filter device of claim 10 wherein said filter cartridge includes flavor pellets to impart taste to said filtered water.

15. The water filter device of claim 10 further comprising a lid that snaps on to said mouthpiece.

16. The water filter device of claim 10 wherein said filter cartridge is operable at an angle of 0 to 90 degrees from a horizontal position.

17. The water filter device of claim 10 wherein said filter cartridge is capable of removing one or more of sediment, particulates, chemicals and microorganisms from said water.
