Do we need Air Purifier?
While browsing the Xiaomi's website I came across this product. The air purifier system. it costs similar to the cooler price. It is 9K and seems to be available for limited amount for now. And that's where I want to know if country like India needs it or not.I know that some of the places in India have lot of pollution. So for them this product can be useful. There is a demo for the product too on youtube which you can check.
However the question remains if you really need the air purifier? I am guessing most of the metro cities do need the Air purifier.
