Reusable, water bottles are exclusively designed for use in the 3M Filtrete Water Station (sold separately), a water filtration system. BPA-free bottles are dishwasher-safe and include a leakproof cap. Slim design allows the bottle to fit in most vehicle beverage holders. Each bottle holds up to 16.9 oz. (500 ml). Threaded, multicolored caps let you color-code according to use or individual.
