GO-3® Water Purifying Cap and Bottle Combo - Clear/Aqua Bottle Meet the GO-3®, the world’s first travel water purifier that purifies water directly in the bottle using the "Power of EO3®," our trademark electrolytic ozone technology. Designed to fit Nalgene® wide-mouth 32 oz or 1L water bottles (included with your purchase), the GO-3® transforms your favorite reusable bottle into a portable and powerful water purification system.

How to Use Fill your Nalgene® bottle with clear water. Attach the GO-3® cap, turn the bottle upside down, and press the power button. Blue Light: Ozone purification cycle in progress (3 minutes). Yellow Light: Contact time for neutralizing harmful microbes (3 minutes). Green Light: Water is ready to drink! After treatment, your water is safer to drink, with a fresh, clean taste. The GO-3® neutralizes harmful microbes and eliminates unpleasant odors.

Features Advanced Technology The GO-3® uses electrolytic ozone, a technology stronger than chlorine for neutralizing harmful microbes. Ozone quickly reverts to oxygen, leaving no chemicals or residues behind.

Perfect Fit Designed exclusively for Nalgene® wide-mouth bottles, including the 1L and 650mL "On the Fly" models. Perfect for travel, hiking, camping, or everyday hydration.

Eco-Friendly & Sustainable Say goodbye to single-use plastic bottles. The rechargeable GO-3® powers up to 40 purification cycles per charge, helping you reduce waste and stay hydrated wherever you go.
