The vertical support includes a visual light display having visual indicators that indicate different parameters of the filter system. A filter cartridge is seated in the base, and defines a first chamber having at least one filter element, and a second chamber in fluid communication with the first chamber. An enhancement cartridge is removably inserted in the second chamber of the filter cartridge and includes an enhancement material for adding minerals to the water. A cover having an opening is configured to slidingly engage the vertical support of the base so that the visual light display is positioned within the opening of the cover and visible to a user. ## Claims ### Claim 1 A water filter system comprising: a base configured for receiving water from a faucet, said base including a bottom support and a vertical support transversely extending from said bottom support, wherein said vertical support includes a visual light display including visual indicators that indicate different parameters of the filter system; a filter cartridge seated in said base, said filter cartridge defining a first chamber having at least one filter element, and a second chamber in fluid communication with said first chamber; an enhancement cartridge removably inserted in said second chamber and including an enhancement material for adding minerals to the water, said enhancement cartridge being removable from said system separate from said filter cartridge; and a cover having an unobstructed opening, wherein said cover is configured to slidingly engage said vertical support of said base so that when the cover is secured to the base, the visual light display on the base is positioned within said opening of said cover so that all of the visual indicators of the visual light display on said base are exposed and directly accessible through said opening in said cover. ### Claim 2 (depends on 1) The water filter system of claim 1, wherein said at least one filter element includes an outer filter layer and an inner filter layer. ### Claim 3 (depends on 2) The water filter system of claim 2, wherein said outer filter layer includes a non-woven, nanoalumina filter and said inner filter layer includes a carbon block. ### Claim 4 (depends on 1) The water filter system of claim 1, wherein said enhancement cartridge includes a housing and a handle member connected to said housing, said handle member including a handle that pivots between a storage position and a use position for facilitating removal of said enhancement cartridge from said filter cartridge. ### Claim 5 (depends on 1) The water filter system of claim 1, wherein said cover includes at least one tab configured to engage at least one groove on said base. ### Claim 6 (depends on 1) The water filter system of claim 1 further comprising a diverter valve connected to the faucet, said diverter valve including a body, a lever rotatably connected to said body and a spigot, an incoming port and an outgoing port, said lever being movable between a first position where the water is directed to said base and a second position where the water is directed out of said spigot. ### Claim 7 (depends on 1) The water filter system of claim 1, wherein said base includes a receptacle having a first opening in fluid communication with said incoming water port and a second opening in fluid communication with said outgoing water port, said filter cartridge being configured to engage said receptacle. ### Claim 8 (depends on 1) The water filter system of claim 1, said visual light display includes a plurality of visual indicators for indicating at least one of battery power and capacity of the enhancement material and capacity of the filter material. ### Claim 9 (depends on 1) The water filter system of claim 1, said visual light display includes a plurality of first visual indicators for indicating a capacity of the enhancement material and a capacity of the filter material and a plurality of second visual indicators for indicating at least one of battery power. ### Claim 10 (depends on 1) The water filter system of claim 1, further comprising a control device and a wireless communication device configured to remotely communicate with a remote mobile device or a remote stationary device. ### Claim 11 (depends on 1) The water filter system of claim 1, wherein said cover includes opposing grooves and said vertical support includes opposing protruding members, and wherein said grooves slidingly engage said protruding members of said vertical support when said cover is attached to said base.
