They destroy viruses, bacteria and protozoa - including Giardia and Cryptosporidium - in just 48 seconds. Globally people rely on Steripen's portable UV water purifiers and appreciate their efficiency and reliability. 

Safe Drinking Water Anywhere
SteriPEN™ is the only portable batch water purifier that uses Ultraviolet (UV) light to destroy waterborne microbes. Whether your source is a clear running stream or a hotel tap, SteriPEN™ kills viruses, bacteria and protozoa—including Giardia and Cryptosporidium—in seconds. 

Easy to use
Just one button does it all. In order to use Steripen’s UV light, all you need to do is to stir clear water with it, 48 seconds for 0.5L or 90 seconds for 1.0L. Wide-neck bottles are recommended for this process.

The lightest being the Ultralight at 76g whilst the Adventurer is less than 225g with batteries, and is lighter than pump filters. 

It is 160 times faster than chemicals, (90 seconds for 1L while chemicals can take up to 4 hours).

Low maintenance
Steripen products don’t require cleaning and are battery operated, which means no pumping. They work for up to 8,000 doses per UV lamp and the automatic dose counter indicates when the lamp needs to be replaced. 

Fits most containers: cups, mugs, water bottles and canteens.

On-board microcomputer controls lamp activation, dose delivery and water sensor.
