As campers and hikers know, even the refreshing clean, cold water of mountain streams may contain may contain Giardia or other ‘bugs’ that can make you sick. But water is a necessity; and sometimes we have to use whatever water is available.

The DayZero UV-H2O-Box provides a way to more safely drink water you find wherever you happen to be – whether car camping or seeking adventure in your RV. 

Ultraviolet light is a robust water sterilization system that kills 99.99% of bacteria, parasites and viruses in suspicious water. It is used worldwide in municipal water systems to treat the tap water you drink.

With the UV-H2O-Box we bring this technology to a small (very tough) device that you can take with you in your car, your RV or however you travel into parts unknown.

Our water box disinfects 1 gallon of water in 1 minute using a built-in, hand-cranked generator, or – when available – it can run on 12V DC power from a car or truck, or power from any ordinary AC electrical outlet.
