Thanks for Alkara softner. It is very useful.. my taps were getting white scales and water was very hard until i install this product. Now i don’t have to wash the taps with any liquid to keep it new and water is very soft. No side effetcs like hairfall or any skin hardneas. Even service is extremely good. They will address the issue within 24 hours of time if you inform to Mr. Naresh. He will send a technician within 24 hours of time and fix the problem. I think i wont see much problems till now rather than cleaning the filters. Zero maintenance product. I loved it…. Thanks to Mr. Naresh.
