There are many alternatives for pure drinking water like bottled water, filtered tap water, or distilled water. I prefer filtered tap water at home because it is more convenient for me. The quality of tap water is not good enough at my place. My water filter gets yellow and needs to be cleaned once a week. Today, I drink filtered water regularly. I drink the filtered water right from the tap in summer without worries. I use Doulton filter. How about you?
