Aquacera 4 Inch CeraMetix Gravity Replacement Filter filter elements utilize our class-leading CeraSyl™ DE (diatomaceous earth) ceramic microporous outer shell combined with our AquaMetix® granular core technology.
AquaMetix® is made from the highest quality NSF component certified (ANSI 61) coconut shell based activated carbon and other superior adsorbent materials including B2 (ANSI 61).

The ceramic shell and our AquaMetix® granular combines mechanical filtration and physical absorption processes to reduce a wide variety of drinking water contaminants of both aesthetic and health concerns.

The pore structure of the ceramic enables sufficient contact time for AquaMetix® to be ideally suited to improving taste and odor as well as reducing chlorine, chloramine, volatile organic compounds, MTBE, lead, mercury, asbestos, arsenic, and fluoride.

The cleanable ceramic shell is designed to remove suspended solids, The CeraMetix® elements have been tested by NSF protocols for cyst, turbidity, particulates, lead, chloramines, and chlorine reduction.

 Filters also fit most other brands of gravity systems.

The CeraMetix GF filter is manufactured to remove suspended solids, pathogenic bacteria, cysts, organic chemicals and improve taste and odor.  The ceramic shell is manufactured to balance flow rate and consistent pore size to provide maximum filtration efficiency. The center of the filter contains our AquaMetix granular media to reduce organic chemicals, fluoride, VOC’s, heavy metals and improve the color, taste, and odor of drinking water. This filter element is designed for gravity filter use and other low-pressure applications. These filters are designed for use in AquaCera® Gravity Filter Systems; they will also fit other makes of gravity systems.
