Philips GoZero Active hydration bottle is a reusable water filter bottle with a sporty appearance. It was designed to provide active users with clean water at all times, be it during a workout or in nature. For this purpose, the Philips GoZero Active hydration bottle can be used with two interchangeable filters that do not compromise the water flow. Whereas the Fitness Filter removes impurities from tap water, the Adventure Filter purifies water from natural water sources. In use, the bottle is simply filled and squeezed when drinking.
