The VIQUA D4 Ultraviolet disinfection system provides a reliable, economical, and chemical-free way to safeguard water for every faucet in your home.

As a point of entry (POE) water treatment solution designed for small to mid-sized homes (and some light commercial applications), the VIQUA D4 UV protects from chlorine-resistant parasites such as Cryptosporidium and Giardia, harmful bacteria like E.Coli, and various microbiological contaminants.

RELIABLE: Constant current feature ensures stable UV lamp output, regardless of power fluctuations 

HIGH PERFORMANCE: UV lamp, tested for consistent output over lamp life (9000 hours) 

ENERGY EFFICIENT: Only uses as much power as a 40-watt light bulb! 

This compact system is recommended for flow rates up to 12 GPM. Capable of 100-240V, 50-60Hz.
