Pure water purifier is a good product. I bought it in 2014. 2 years I ’m use to, But I seem to have no shortage .This allows us to get clean water. To me and my Family prevents many diseases. These are the filters of the water Wipe dirt. The company is also the best in service .Once the service is one call.Repeated calls do not have to. The company is a very good service in Agra. My experience has been very good to buy the product, I would suggest buying it. Secure water purifier is also good water purity criteria. Tests of the water purifier and pure nothing gets spoiled. But there is a minus When the water purifier is over.then The water takes a long time to re- pure.
