Survival Gear Review | SteriPEN UV Light Water Purifiers

There are many ways to treat and sterilize water. There are high tech ways, low tech ways, and lots of in-between ways. One isn’t necessarily better than the other but redundancy is important. Remember the old military saying: “Two is One and One is None”. You have to have more than one way to do stuff, especially something as important as sterilizing your drinking water. Today we are going to review one of the high-tech ways to sterilize water: The SteriPen.

SteriPEN Description

The SteriPEN is a compact, lightweight, battery-operated devise that purifies water by emitting Ultra-Violet (UV) light. There are about a half-dozen models to choose from, but all of them kill 99.9% of all bacteria, viruses and protozoa that is present in the water.

Using UV light to sterilize water is nothing new: there is a low-tech way called the SODIS method that uses the suns rays to do the same thing. SODIS though requires 6 hours of sunlight for a liter of water. The SteriPEN takes only 90 seconds for 1 liter.

Here is a quick video showing the SteriPEN in action:

Conclusion

The SteriPEN gives users the ability to sterilize their drinking water at the touch of a button. The units are lightweight, durable, easy to use, and much more convenient than lugging around a large supply of water. They offer a tasteless, chemical free way of disinfecting water on the go. There are plenty of models to choose from, their main differences being differences in the capacities of the batteries, their size, and their weight.  One of the great benefits of any SteriPEN is it’s ability to kill viruses, such as the viruses that cause hepatitis. I feel that no matter what model of the SteriPEN you happen to choose, it will be an important addition to your First Aid  and Emergency Kits.
