I am using this air purifier for last 1 year. I changed it's both filters namely HEPA and activated charcoal filter today. Then I realised, how much dust, PM 2.5 it has reduced in last 1 year. I think it works well for 8 months with running hours of 8 hours per day. After 8 months its efficacy decreased may be because of clogging of filters due to dust. The thing is that both of the filters could not be cleaned but has to be replaced each time. So, this brings its recurring cost in long run because both of them costs 4000 rs. I think this will be applicable to all air purifiers. But in recent times air quality deteriorated badly. We, humans, are responsible for this. We should check pollution, otherwise coming generations will face dangerous consequences.
