Aqua Fresh Grand plus is an awesome and fantastic ro purifier as many available in market. It is value for money also. The service of RO is at time and first four service is free. If you are planing to buy an RO then I refer this one. Because it is uner 15000 rs. And so cool Ro. I clean 10 to 12 litre water in a hour. And less electricity is used. I use tgi RO from last 8 month and it work very good and the TDS of water is reduced by thu RO is very effective. Where I live there is the TDS of wather is near to 2000. But after purifing the water by this RO is 120 which is so good
