How long should I wait before drinking the water that has undergone ozone treatment?
Since the water quality varies at different places, the waiting time will differ accordingly. It is recommended to wait for 45 minutes for 20 liters of tap water. If the water quality is poor, then you will need to wait for a longer time. There is an identification method to determine whether the water is ready. Once the bubbles are clear, then the treatment is completed. (The treated water should be filtered before drinking).
