I never suggest people to drink purified RO water. Water contains more minerals so when you filter it, you will not get those minerals in our body. Its like eating sugarcane after taking juice from it. Useless one. Clay pot is always best and it’s a natural purifier. Minerals from water will not be losen. Healthy water and doesn’t affect cold. Best for summer. Cleaning is also easy. Dust will settle down when you keep water in pot overnight. Chillness will be added to the water naturally. Go Green!
