The Gravity Max with Zeolite water filtration filter element is the top of the line filter element produced by Doctor Agua.

This filter element is made from a 100% CeraSyl™ diatomaceous earth ceramic shell (0,5 microns, absolute) combined with zeolite and an activated carbon block plus silver particles. The CeraMetix® technology combines the elements of the ceramic shell with AquaMetix® core inside, composed of at least two types of activated carbon, combined with zeolite minerals. All of them are melded and structurally bound with polymers into a solid, highly porous block to ensures filtration consistency and high performance. This offers an excellent reduction of aluminum, arsenic, cadmium, chloramines, chlorine, cysts, fluoride, lead, mercury, nickel, radionuclides, silver, tri-halomethane, VOC’s and zinc in a single, revolutionary ceramic filter element. The Gravity Max with Zeolite filter candle represents a revolution in the world of water filtration!
