Nu Flow Water Filtration Systems cleanse municipal water and produce clean, safe and great-tasting water from every faucet in your home or building. Carbon filtration safely and thoroughly removes chemicals, toxins, sediments and particulates from water. Nu Flow’s Ultra-Filtration further removes potentially lethal waterborne contaminants such as Legionnaire’s Disease, as well as E-Coli viruses which are frequently released into the water supply when municipal systems fail, perhaps after a local water main break.
