You are currently viewing SteriPen


How does the SteriPen work? When inserted into contaminated water, the UV light destroys the ability for bacteria and viruses to reproduce. Once the virus or bacteria absorb the UV light, it can no longer reproduce, effectively killing the organism and making it harmless and safe for you. It however does not change the smell, taste or the color of the water.

To use a SteriPEN, you insert the wand section into the water you wish to purify for the set time. Its is recommended to use a particle or sediment filter with a carbon filter before UV filtering.SteriPen offers a pre-filter that’s designed to remove particles as small as four microns in size.

Below we have listed most models of the SteriPen and the prefilters from around the web.
