The WaterMaker Five features a four-stage prefilter, membrane, and postfilter housed in a single cartridge. The fifth stage, an in-line carbon filter, is placed between tank and faucet. The high capacity sediment prefilter removes dirt, silt and other suspended solids; the granular activated carbon (GAC) prefilter removes chlorine taste and odor: the 50 gpd reverse osmosis membrane removes salts and other impurities; a GAC postfilter provides fresh-tasting, clear drinking water.
