The EWS DWS-UV is an under-sink drinking water system that combines three stages of carbon filtration with a fourth UV disinfection stage. The carbon filtration stages are designed to reduce chlorine, chloramine, PFAS, VOCs, lead, and cysts, which addresses both the taste and odor of tap water as well as a range of chemical contaminants.
The UV stage adds a layer of protection beyond filtration alone: it uses ultraviolet light to inactivate 99.99% of bacteria, viruses, and other microorganisms as water passes through, which is particularly relevant for households on well water or anyone wanting extra peace of mind about microbiological contaminants. Because it filters on demand rather than filling a storage tank, there's no standing water sitting in a reservoir and no water wasted in the process.
The system installs under the sink and feeds a dedicated countertop dispenser. Filters and the UV lamp are replaced annually as a set, and the system is made in the USA.
