In the Zombie Apocalypse one of the hardest to find survival items will be fresh drinking water. There are a ton of products out there to purify water but the SteriPen Handheld Water Purifier is our favorite. I bought one last summer and it works perfectly. The only drawback is that it takes 2 AA batteries. Hopefully a crank version will hit the market soon. If you know of one please let us here at Don’t Get Bit know. SteriPEN products use ultraviolet (UV) light technology to purify water, destroying more than 99.9 percent of bacteria, viruses and protozoan cysts such as giardia and cryptosporidia.
The EPA officially recognized the use of ultra-violet as a proven, viable technology in 1996: “Ultraviolet (UV) radiation has been found to be an effective disinfectant…. a useful small systems disinfection technology option.” UV purification works as the ultraviolet energy emitted by the light is absorbed by the cells of the microbe, preventing cell enzymes from ‘reading’ its DNA. Without intact DNA, microbes can’t reproduce to make you sick. The process is simple but effective, destroying over 99.9 percent of harmful microorganisms.
Purifying water with UV light offers many advantages. In addition to being safe and effective, UV light does not alter the taste, pH, or other properties of the water, and works without the introduction of chemicals to the water.
SteriPen is available on Amazon for $65
