How do you make sure that the water you’re drinking is safe? One (almost) sure way is to boil the water. Filters will only be able to remove the visible and larger particles from water, but you need to boil water in order to kill the bacteria. What if you don’t have fire or a suitable container for boiling water? Luckily, there’s another solution.
The SteriPEN ADVENTURER Ultraviolet Water Sterlizer is an ingenious tool in a compact package.
SteriPEN is a handheld device that uses ultraviolet rays to kill waterborne microbes, including viruses, bacteria and protozoa (for example, Giardia and Cryptosporidium). With the SteriPEN, you don’t need to boil water and you don’t need a special container. Just put the SteriPEN in the glass / container of water, press a button, and wait about a minute. That’s it.
SteriPEN uses 2 lithium ion CR123 batteries, and there’s even an optional solar charging case. One set of batteries is good for sterilizing 50 litres of water.
SteriPEN isn’t cheap at $130, but it should more than pay off for itself over time.
