The “Caspian” stoneware water filtration crock—where fashion meets form. Each crock is a unique handcrafted work of art. Inside, the CeraMetix® Ceramic Filter Candle removes bacteria, aluminum, arsenic, cadmium, chloramines, chlorine, cysts, fluoride, lead, mercury, nickel, radionuclides, silver, tri-halomethane, VOC’s, zinc, pharmaceuticals, and more (See filter specs below, from AquaCera). The “Caspian” 16 inch clearance means it can fit underneath a cabinet. Gravity fed filtration system: enjoy pure water on tap, anywhere in your home. No power or running water required. Great for lake houses and cabins, for filtering pond and river water, for emergencies, or for removing what municipal water companies miss.
