Shop by category Whole-home filtration (CWL series): city or well* water carbon filtration for chlorine/chloramine, taste, and odor Whole-home filtration + conditioning (EWS / SPECTRUM): adds ICN salt-free conditioning to help reduce scale on plumbing and water heaters Under-sink drinking water: ESSENTIAL DWS (3-stage carbon), MAX FLOW high-capacity faucet filtration Reverse osmosis: ESSENTIAL RO3/RO4 systems, with optional ultraviolet (UV) models for added microbial protection Filter replacements & parts: annual under-sink cartridges, RO membranes, and system-specific kits Quick choosing guide Whole-home vs point-of-use: choose CWL for whole-home filtration; step up to EWS/SPECTRUM if you want salt-free conditioning along with filtration. City vs well water: for municipal water, select chlorine/chloramine-rated models. For wells, review a recent lab test and match any specialty needs (iron, sulfur, bacteria) with the proper EWS solution. Drinking water choices: prefer mineral taste and no storage tank? pick DWS/MAX FLOW . Want the most removal and “flat/distilled” taste? pick RO3/RO4 and add UV where you want microbial protection. Size it right: match system size/valve to your plumbing (3/4", 1", 1-1/2") and household flow so pressure stays strong. Maintenance: under-sink filters are typically replaced annually; whole-home media has multi-year life per model. Always follow the EWS service guide. *Well water: review a current lab analysis before selecting equipment. Some wells may require pre-treatment or specialty filtration.
