Proven technology!
For over 100 years, ultraviolet (UV) light has been used by bottling companies and in water treatment plants to make water safe to drink. SteriPEN’s creates UV light that disrupts the DNA of microbes in water. Without functional DNA, microbes can’t reproduce or make you sick. SteriPEN is effective against pathogens that cause diarrhea, dysentery, cholera and other waterborne illnesses.

One thought on “Military

  1. James Parsons says:

    This would be great to have while I am camping. I would want to test it out before I have to depend on it. If the military use it though, it’s usually pretty reliable.
