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

  1. 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.
  2. 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.
  3. 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.
  4. Size it right: match system size/valve to your plumbing (3/4", 1", 1-1/2") and household flow so pressure stays strong.
  5. 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.

Pro tips: For whole-home installs, place the system after the meter/pressure reducer and before branches; bypass hose bibbs if you prefer. Verify chloramine vs chlorine on city reports, size by plumbing diameter/flow, and schedule annual under-sink cartridge changes. Considering RO? Plan space for the tank (RO3/RO4) and add UV if desired. Questions? Send your water report (or city name), pipe size, and household size—we’ll dial in the right EWS system and filters.
