Three Simple Steps to Safe Water

Making brine for camping water purifier

Step 1: Mix brine

Make your saltwater solution at home or in the field using the water you are going to treat. Use any salt, including common table salt, sea salt, and more. Simply add salt up to the brine bottle fill line (~1 tsp), add water, and shake. Each brine bottle holds 12 doses. The H2gO Purifier also holds salt onboard to make two more bottles of brine for an extra 24 doses.

Simply add brine, select the volume of water you want to treat, and press the button to create disinfectant. A single dose can treat anywhere from 1 to 20 liters of water at a time, inactivating viruses and bacteria. A double dose will also destroy protozoa.
