Zero B Solar is indeed different. Its neither RO nor UV. But its quite advanced as its has 6 stages of purification which are capable of removing every non impurity and contaminants that can be present in water. Its a fair option when someone don’t require an RO. any ways its lot more cheaper than RO and even some UV’s. I got it for 7490 only.
The Zero b salesman who came for water test told me since the water TDS level is low at my place not going with proper RO would also do. and it saved my money. Thanks to his honesty. It can simply hanged it on the wall. Another good point, it doesn’t require electricity to work. So I again save some money as well as energy. And its not dependent on sunlight, even our normal tubelight would do.
So, the product is good. And the company to which it belongs to is quite old and well known.
All I hope now is that my journey ahead with Zero B solar is fine.
