Have been using the product since the last 15 days. It works like a charm. Cleans the air perfectly well. During Diwali when the outside reading of PM 10 was above 1000 and PM 2.5 was around 700, the purifier took 15-20 minutes to turn the air quality of my closed bedroom (12x12 feet) from very dirty (red) to dirty (reddish violet). It took around 1.5 hours to turn to blue (safest level of the air sensor).

The product is good and senses the air quality and displays the colour. Blue for good air, etc. But do not know is the sensing is correct or not. But overall it is a good product and kids are getting good air at least within home.

Using it for last 24 hours in a small 110 sq ft room. Not sure whether it's doing its job properly. As per its sensor, it is cleaning the air. But I don't feel any drastic change as of now. Liked its sleek and portable design.
