Our GAC filters are used as an effective filter for removing taste and odor. Every GAC Filter is made from coconut shell carbon. These filters are used as a polishing filter which adds a sweet taste to the water.

Our carbon block filters are used as an effective filter for removing free chlorine. Every filter is made from coconut shell, palm or nut shell, and coal based carbon. These filters are used to remove contaminants, reduce chlorine, and absorb chemicals.

Sediment filters are used as an effective filter for removing solid particles. Every sediment filter is made from spun polypropylene. These filters are used to remove substances like sand, dirt, silt, and rust.

FOR BEST TASTING WATER, the filters should be changed out once per year.

Replacement Membrane is not included in two and three sump sets and should be changed out every two years.
