Doesn't provide purified water properly. Review on Pureit Water Purifier

I have used Pureit Water Purifier 14 litre in the year 2015. I was charged 1499 INR. The purifier used to provide good service properly but after 4 months I have found the purifier cannot able to filter the water properly. We have seen dirts particles after filtering of water. We have changed the refile at that time, the refile cost us 450 INR, but the same problems has happened and I have called to customer care the technician has visit to my house and provide service. But the customer care technician is not very skilful because after 6 months the same problems has happened, though we have four members in the house we need to refile it every 45 days. It doesn't looks good and its not durable as the water tap has been broken Later we have to changed the filter due its bad performance. So I can suggest everyone to select other purifier rather than this.
