I got this product after going thru lot of reviews of other purifiers and the cost etc. This seemed real good. I have had issues but they were serviced quickly. The engineers seem to charge extra on the spares, including filters or valves, no bills! First time it was the extra valve to help switch from bore water to metro water etc. he charged me 750 but no bills. Next was the filter(which needs to be replaced once in 2 months) they charged me 150-175 but the actual cost for it in the service station was 120 only.
It was still OK until today, when I got ants when I filled my water bottle. Not sure what attracts ants to water. As far as I know ants hate water.:)
I have called for the engineer, lets see what he says.
