This listing is for BOTH the GO-3 Pod AND a Water Bottle. Meet the GO3 Water Bottle Pod. It is the first of its kind in the world, a water bottle cap that will make water safer, right in the bottle. It fits your favorite Nalgene wide-mouth 1 Liter water bottle, (32 oz) or the Nalgene 650 ML "On the Fly" water bottle, (a narrower size will fit most car cups). Please note this cap will not fit other wide mouth bottles - only Nalgene Brand. THE GO3 IS THE ONLY BOTTLE POD WITH THE POWER OF EO3, OR ELECTROLYTIC OZONE. Stronger than chlorine when dissolved in water, ozone kills microbes fast, and quickly reverts to oxygen. Leaves nothing behind but a fresh clean taste. To use, simply fill the bottle, attach the pod, turn it upside down, and press a button. The treatment time is 3 minutes. Youll never have to buy a plastic water bottle again. This pod will make all water safer to drink, smell and taste great - it even helps to destruct chlorine. And is it ever effective! Laboratory tested against common microbes that can make you sick. Ozone is more powerful than chlorine, yet reverts quickly to oxygen, so yay! No chemicals! Its integrated, a rechargeable battery will last for 80+ uses (=80 Liters of water), before needing to recharge. Includes military-grade “pod-pocket”, wireless charge pad. Nalgene bottle sold separately.
