I have purchased this air purifier and I am using this purifiers 5 months ago and I experience that this purifier is not so good because it only purify the air of a small room it cannot purify the air of a big room and this is very costly as compared to the other purifier available in the market. It does not purify the air completely, some dust particles remain in the air. Sometimes it does not work properly I don't know what is happening. So from my suggestion, this is not a good quality of air purifier.
