A water filtration housing containing a pressure vessel configured to receive a water filter cartridge; a ring enclosure attachable to an open, top end of the housing enclosure; an interface tower including a user interface; a lid assembly removably attachable to the ring enclosure, the lid assembly including (i) a pressure cap and gasket for maintaining a given pressure in said pressure vessel and (ii) a rotatable lever for disengaging the pressure cap from the pressure vessel thereby releasing pressure therein. A mating system between the lid assembly and ring enclosure prevents the lid assembly from being attached to the ring enclosure in a misaligned fashion. RFID technology may be used for identifying the water filter cartridge installed therein and wireless communication technology (e.g., Wi-Fi) to transmit collected system data (e.g., water usage) to a central location for analysis such that the customer is provided with, for example, operational suggestions.

1. A water filtration system comprising: a housing enclosure configured to contain a pressure vessel configured to receive a water filter cartridge;inlet and outlet connectors configured to receive tubing for carrying source water and dispense purified water, respectively;a ring enclosure attached to an open, top end of the housing;anda lid assembly removably attachable to said ring enclosure, said lid assembly including (i) a pressure cap and gasket for maintaining a given pressure in said pressure vessel and (ii) a rotatable lid lever for engaging and disengaging said pressure cap and pressure vessel thereby setting and releasing, respectively, pressure within said pressure vessel. 2. The water filtration system of claim 1 further comprising a rotatable rear lever attached to said housing enclosure, said rotatable rear lever, when closed, preventing said rotatable lid lever from being opened. 3. The water filtration system of claim 1 wherein spaced teeth of said lid assembly and spaced teeth of an outer surface of said ring enclosure are positioned to lock said lid assembly onto said ring enclosure in a correctly aligned manner. 4. The water filtration system of claim 1 wherein said lid assembly further comprises a leaf spring connected to said pressure cap and a compression cap. 5. The water filtration system of claim 2 further comprising a battery compartment concealed by said rotatable rear lever when closed. 6. The water filtration system of claim 1 wherein said user interface is part of an interface member integral with said ring enclosure. 7. The water filtration system of claim 6 wherein said user interface comprises a user button and indicator lights. 8. The water filtration system of claim 3 wherein said lid assembly teeth and said ring enclosure teeth are spaced to permit said lid assembly to be removed or attached to said ring enclosure with less than a forty-five degree turn of said ring assembly. 9. The water filtration system of claim 3 wherein said spaced teeth of said lid assembly are on an inner surface of a compression cap thereof. 10. The water filtration system of claim 1 wherein said rotatable lid lever is configured to raise said pressure cap relative to said pressure vessel thereby causing said pressure cap to force said gasket against an inner, upper surface of said pressure vessel. 11. A water filtration system comprising: a housing enclosure configured to contain a pressure vessel configured to receive a water filter cartridge;a lid assembly removably attachable to a top of said housing, said lid assembly including (i) a pressure cap retaining a leaf spring and gasket for maintaining a given pressure in said pressure vessel and (ii) a rotatable lid lever for engaging and disengaging said pressure cap and said pressure vessel thereby setting and releasing, respectively, pressure within said pressure vessel;source water input connector and purified water output connector;a rotatable rear lever attached to said housing and positioned to overlap one end of said rotatable lid lever such that said rotatable lid lever cannot be opened until after said rotatable rear lever is opened. 12. The water filtration system of claim 11 wherein spaced teeth of said lid assembly and spaced teeth of an outer surface of said housing enclosure are positioned to lock said lid assembly onto said ring enclosure in a correctly aligned manner. 13. The water filtration system of claim 11 wherein said lid assembly further comprises a compression cap. 14. The water filtration system of claim 11 further comprising a battery compartment concealed by said rotatable rear lever when closed. 15. The water filtration system of claim 11 wherein said user interface comprises a user button and indicator lights. 16. The water filtration system of claim 12 wherein said spaced teeth of said lid assembly are on an inner surface of a compression cap thereof. 17. The water filtration system of claim 11 wherein said rotatable lid lever is configured to raise said pressure cap relative to said pressure vessel thereby causing said pressure cap to force said gasket against an inner, upper surface of said pressure vessel. 18. An article comprising: a pressure vessel defining a chamber with an opening at one end thereof;a pressure cap having an outer lip circumscribing a perimeter thereof;a gasket dimensioned to reside along said outer lip;wherein said pressure cap and gasket are configured to insert into said opening of said pressure vessel such that said pressure cap, when engaged, forces said gasket against an inner surface of said pressure vessel to form a seal about said opening in said pressure vessel;wherein the pressure vessel includes a second opening for receiving water,wherein an upper surface of said outer lip is angled upward, andwherein water pressure within said pressure vessel creates an upward pressure against said pressure cap forcing said angled surface of said outer lip further upward into said gasket, thereby pushing said gasket further against an inner surface of said pressure vessel proximate said opening. 19. The water filtration system of claim 10, wherein said pressure cap has an outer lip circumscribing a perimeter thereof, andwherein said gasket is dimensioned to reside along said outer lip. 20. The water filtration system of claim 19, wherein said pressure cap and gasket are configured to insert into said pressure vessel such that said pressure cap, when engaged, forces said gasket against an inner surface of said pressure vessel to form a seal about said pressure vessel. 21. The water filtration system of claim 19, wherein an upper surface of said outer lip is angled upward, andwherein water pressure within said pressure vessel creates an upward pressure against said pressure cap forcing said angled surface of said outer lip further upward into said gasket, thereby pushing said gasket further against an inner surface of said pressure vessel. 22. The water filtration system 17, wherein said pressure cap has an outer lip circumscribing a perimeter thereof, andwherein said gasket is dimensioned to reside along said outer lip. 23. The water filtration system of claim 22, wherein said pressure cap and gasket are configured to insert into said pressure vessel such that said pressure cap, when engaged, forces said gasket against an inner surface of said pressure vessel to form a seal about said pressure vessel. 24. The water filtration system of claim 22, wherein an upper surface of said outer lip is angled upward, and wherein water pressure within said pressure vessel creates an upward pressure against said pressure cap forcing said angled surface of said outer lip further upward into said gasket, thereby pushing said gasket further against an inner surface of said pressure vessel.
