If you live in NCR this purifier is must have.Price is descent and its effective.I have been using it for more than a year now and fully satisfied woth it.
It has 3 filters.Carbon filter rwmoves all the bad odours from the room and hepa filters for very small particles from air.
You can see that the pre filter gets filled every 20 days and needs cleaning.So if you want to stay healthy in such polluted regions this product is must have
