Real Protection from Contaminants. The CWL Spectrum is an advanced filtration appliance designed to filter all water throughout your home, providing truly healthy water to every sink and shower. All our whole home filtration appliances utilize the highest quality, highest iodine rating granular activated carbon (GAC) in order to effectively remove and reduce chlorine, chloramine, VOCs, THMs, pesticides, herbicides, pharmaceutical residues, obesogens, and more. Our filtration appliances are in use worldwide by hospitals, medical centers, health and fitness centers, military, professional athletes, and thousands of personal homes worldwide.
Healthier Home & Lifestyle. All EWS and CWL appliances are designed to prevent you and your family from drinking, absorbing, and inhaling various contaminants and carcinogenic (cancer-causing) chemicals. Enjoy chlorine-free, healthy, filtered water for your entire home – drinking, bathing, showering, pets, plants, pools, spas and plumbing. Enjoy healthier skin and hair, and delicious odor-free water from every sink. Alleviate symptoms of asthma and allergies by providing chlorine-free filtered water for showering and humidifiers.
Easy to Install & Self-Maintains. Our whole home filtration appliances are hassle-free, self-cleaning, user-friendly appliances that only require a filtration media change about every 10 years (based on your local water conditions and usage). Your EWS or CWL appliance installs easily like a water heater at the main water supply line to your home. Automatic backwashing prevents bacterial build-up and provides a continuously renewed surface area for filtration (plus, the backwash water is completely safe and filtered, and may be used for plants, gardening, pools, livestock, and pets).
The Highest Quality Possible. We are known throughout the industry for our impeccably high standards, quality materials, and American manufacturing. Your CWL Spectrum contains 85 pounds (2.5 cubic feet) of the highest grade granular activated carbon (GAC) filtration media, which has ZERO chemical additives, fillers, metal resins or metal-based media, or silver impregnation (which is silver nitrate, a pesticide). Meets or exceeds all FDA, NSF, ANSI, and California State standards and compliances.
Environmentally-Friendly & Cost-Effective. Our appliances are the environmentally-friendly, maintenance-free choice to filter and condition your water — no salts, no chemicals, no corrosive softeners, no brine discharge, no gimmicks. Replace expensive and wasteful bottled water with healthy, filtered EWS water from every sink in your home. Our tanks and parts are recyclable and our proprietary filtration media is completely compostable and biodegradable. Our advanced digital valve head requires an ordinary electric outlet and consumes only the power of a doorbell.
Protect Your Home & Appliances. Aside from thoroughly protecting you and your family from contaminants, our appliances protect your kitchen appliances, water heater(s), and bathroom fixtures from the ravages of chlorine, chloramine, and volatile organic compounds (VOCs), which harm fixtures, heating elements, finishes, surfaces, connections, and internal parts.
*WELL WATER WARNING Well water is required to have independent, complete and proper testing of your well water to determine the proper course of action in order to specify the correct system(s).
Optional: Any EWS or CWL whole home appliance may be combined with one of our softeners (preferably hot-side only) and/or ESSENTIAL sink filtration product based on customer preference or local water conditions.
