I bought Z8 model 10 days back everything is fine but I am having diarrhea continuously I think bacteria is growing inside the purifier. The design of purifier is faulty since 800 ml water remains at the bottom of the storage tank even after emptying it completely so if you switch the purifier after few day 800 ml water will be infected with bacteria and than you will be adding more purified water to already infected water in storage tank.Very disappointed to buy such a faulty design by paying a premium
Update1: I bought a TDS meter to check truth to my horror the filter is not cleaning the water at all I am getting 189 reading for tap water and 180 reading for filtered water.Now I understand why rice cooked with this water was smelling bad horrible not even 10% difference in quality of water after using this purifier. I am facing sleep chills from last 10 days I did not suspect due to water. I do not know how many heavy metals I have ingested until now due to which I am facing sleep disturbances. I will put a case on this company for playing with my family health.
