The GoZero Daily Filter effectively improves the quality of tap water by reducing chlorine, lead, and pesticides. Healthy and fresh water without compromise! The bottle features a dust-proof cap that keeps the mouthpiece clean. Thanks to the sealed design, no water enters the bag. All parts except the filter are dishwasher safe (up to 50 degrees Celsius). Enjoy delicious water for less than bottled water and with less waste. The BPA-free Tritan bottle is more durable, lighter, and resistant to heat and breakage. The bottle fits most standard-sized cup holders. Simply insert the filter into the straw and reattach the straw to the cap before screwing on the bottle. You can add ice cubes to the bottle. The wide opening allows you to fill the bottle with standard ice cubes. The Daily Filter, made from highly porous activated carbon fiber, enhances the quality of tap water by reducing chlorine, lead, and pesticides without affecting water flow. Just fill the bottle, drink, and enjoy the taste.
