I am a user of Kent Ro Wonder. Water Purifiers from Kent Ro combine the best of technology and expertise. It filters out bacteria, virus and new age contaminants like lead and arsenic very effectively.
The water purifier can hold water up-to 8 litres after purification.
The purifier can filter up-to 15 litres in an hour and auto starts the purification process and auto shuts once it is done. Apart from this there is a filter change alarm in the product and the dealer offers a 1 year warranty on the product. Overall its a good product to buy.
