I find best ac from this Hitachi company and it's result is very best. I daily turn on the AC and this actually fresh air and the other side is purification system out of the backside of the AC .
Power consumption is slightly high. I bought from the ac flipkart in online payment very less amount of maintenance. This ace I using for a month and I no problem with this Ac including to air related and the cooling the room from this Ac I would to recommend this Hitachi AC who's only for cooling .
