Tired of using common without water purifier we switch to the eureka Forbes. According to our need eureka Forbes sales man suggested us to buy aguagard compact purifier and truly he suggested us right. It is very easy to use anybody can use it. It has three buttons one for switching on and off, the second one for turning on the flow of water and third one for the sound reminder to notify and justify that machine is an and whether the water is flowing or not. It is quite durable and works finely as we are using it from past five years i.e from 2013. Without any problem. It requires maintenance of changing carbon rod every 4 to 6 months. Carbon rod costs 800 rs. This is bit costly. Service and support are also good but sometimes they do not give satisfied answer. So we done contract of maintenance privately from outside. I recommend this wholeheartedly. For hygiene purpose change the water daily if possible. Hope it would be helpful to you
