The availability of safe drinking water could mean the difference between life and death. The SteriPEN UV Water Purifier uses ultraviolet light to rid drinking water of bacteria and other dangerous elements without the need for chemicals, boiling or other harsh treatments.
The SteriPEN purifier is highly portable (small and lightweight), which means you can easily bring it on camping trips and during your business travels. It is powered by commonly available AA batteries. It can purify about 16 oz of water at a time. The SteriPEN costs around US$149.
