Ultra features an internal battery that's recharged from any USB power source; connect the included USB cable and start charging from a solar panel, laptop or car power port

Low-power indicator lets you know when battery needs recharging; when fully charged you can treat 50L

Ultraviolet (UV-C) light rays safely sterilize clear water by destroying 99.99% of protozoa (including Giardia and Cryptosporidia), bacteria and even viruses

SteriPEN protects you from risks that cause botulism, cholera, dysentery and typhoid, just to name a few

To purify your water, just press a button and gently agitate the water with a quick stir

Purifies 16 fl.oz. of water (cold or warm) in less than a minute or treat 32 fl. oz. in 90 seconds

Ultra is designed to fit perfectly into store-bought bottles of water; just insert the Ultra into the bottle, flip the bottle upside down and start treating the water

Small size fits most containers—use it in cups, mugs, water bottles and canteens

SteriPEN turns itself off once ultraviolet treatment is complete; can be used up to 8,000 times!

Watertight seals keep water away from the electronics; rubberized inset grips for secure handling in wet conditions

Long used by municipal water districts and bottling companies, low-level UV-C light treats water safely, and unit's light will not damage eyes or skin

Use only on clear water, as cloudy, sediment-laden water hinders effectiveness; FitsAll prefilter (sold separately) clears particulates and debris from water

Includes SteriPEN Ultra water purifier, USB cable, carrying case and instruction manuals
