MYBOTTLE WATER BOTTLE PURIFIER The only EPA-registered water purifier bottle on the market. The Katadyn MyBottle is one of the top portable water filters available. It supplies 7 fluid ounces of drinking water in a minute and is sufficient for up to 100 liters. The lightweight MyBottle Purifier weighs a mere 8 ounces, and because it is made of food-grade polyethylene, it also has a neutral taste. Its large opening enables it to be easily cleaned by hand or in a dishwasher. The three-stage water filter is the heart of this perfect outdoor drinking system. It eliminates harmful viruses, bacteria, and protozoa. Another benefit of the three-stage water filter is that it improves the taste of the water. No more of that swampy taste of decayed water in your mouth – but the living freshness of spring water! BPA free. • Virustat kit: complete cartridge replacement. • Cyst filter: replacement for the middle stage of the purifier cartridge.
