The mark consists of A three-dimensional configuration comprising a darkly colored cuboidal body is raised above a rectangular base with rounded corners. The cuboidal body has a front surface, a rear surface, a pair of side surfaces, and a metallic, glossy top surface. The front surface is dual textured with a matte central panel longitudinally disposed between the base and the top surface. The texture of the central panel is contrary the texture of the rest of the cuboidal body. The central panel includes a digital display window centrally disposed more proximal to the top surface. The digital display illumines a pH level and status indications for each of two filters and communicates a selected mode of operation, such as acid, alkaline, purified, levels, and a flow meter readout. The rear surface is flat and includes a plurality of mounting holes indented therein whereby the cuboidal body may be mounted to a vertical surface. Each of a pair of removable panels is disposed in opposite position in the rear surface. Each removable panel extends laterally and wraps around to a corresponding side surface. Each of the pair of removable panels includes a pair tabs for manual engagement at the rear surface enabling removability from the cuboidal body. Between the front surface and the top surface, an inclined edge houses a plurality of buttons manually selectable for operation. Each of the plurality of buttons is rounded and includes an identifying icon. The top surface is flat and has a spout member off-center thereon. The spout member includes a metallic, articulated member that terminates in a metallic nozzle.
