The Ecomo Bottle Smart Personalized Water Bottle helps you get rid of contaminants in your water. Fill the Ecomo Bottle with water from any source: your home faucet, a nearby water fountain, or a stream. Then test the contaminants in your water with a shake. View the water quality on the bottle's LED display or the Ecomo mobile app. Once you know your water quality, you can filter the water with a simple twist. The bottle’s three-in-one filtration system contains an activated carbon fiber, ion exchange fiber, and a nanofiber membrane. With this technology, Ecomo Bottle removes most major contaminants, such as pesticides, petroleum products, bacteria, and most heavy metals. With Ecomo Bottle, you can monitor total organic carbon, dissolved solids, turbidity, and water temperature.
