People often find their bottles get smelly over time because the daily cleaning process doesn't get rid of odor-causing bacteria. With UV-C LED technology built into the cap, the Philips GoZero Smart bottle eliminates up to 99.99% of all bacteria, effectively preventing unpleasant smells. It also eliminates waterborne pathogens to keep water fresh and clean tasting so that you can drink confidently without creating single-use plastic waste. This bottle has a timeless rounded design, and the special powder coating gives it a comfortable grip and a natural clay-like touch. The extra-thick rubber handle gives it a stylish look.
