When you’re out hiking in the mountains, that crystal clear stream may look safe to drink, but don’t bet on it. There is a big difference between the water you may come across out in the great outdoors and the treated water you’re accustomed to from the tap in your home. A wide variety of harmful organisms could be waiting for you, like bacteria, protozoa and viruses.

One solution to making sure your water is safe to drink is the Pure™ Electrolytic Water Purifier from Potable Aqua, a system that turns food-grade salt into a powerful mixed oxidant disinfectant, capable of purifying even the dirtiest of water. All you need to do is add a few drops of brine solution into the compact device, and The Pure Electrolytic Water Purifier can easily purify up to 20 liters of water without any pre-filtering or pumping. Running on an electric charge, this filter can purify 150 liters on a single charge, is USB chargeable, and even features a built-in solar panel for fail-safe back-up charging.

Designed to meet military-grade durability standards, The Pure Electrolytic Water Purifier is a great option for camping and hiking, or any situation in which you may need to stop for a cool drink.
