Do Just One Thing
If you use a reusable water bottle at home, you might wonder how long the water inside is safe to drink. The answer: about 24 hours. According to Better Homes & Gardens, water that sits uncovered for eight hours or more can absorb carbon dioxide from the air, which lowers the pH and can affect the taste. The bigger concern, however, is the bottle itself -- every sip introduces bacteria. If the bottle sits near a heat source, that can accelerate bacterial growth. Wash bottles daily, refill them often and pour leftover water into your houseplants so none goes to waste.
