Being concerned about family I have always made sure to go for good and reputed brand products in water purifiers, irrespective of their rates & maintenance. Last year, my close relative recommended me about Zero B Water Purifier. I was convinced by their services procedure. It has been a year since I am using this purifier. The performance and taste of water is good.water after purification is good.They are providing services on every three month. I am using this wave purifier. never faced any issue with it.
