KENT Super star 7 L RO is one of the best water purifier available in the market right now. After purchasing it the service center employee itself install the device in your area. The most important feature about it is that the water is pure and with added minerals. Kent RO is built with technology that comes with an indicator which indicates to replace its filter when required.
Since is a water storage device hence cannot be operated on running water. you just need to connect the tap with filter and it automatically filters the water. The filter is durable for long term use and can be used for 2 years from the day of installation. The design is slightly bulky and takes a lot of space on your wall.
The only drawback I face is that it works on electricity and a lot of water is being wasted at the time of filtering. Overall the product is up to the mark.
