I use it only in the Summers. Mine is a 3 star window. Power consumption is relatively low and quality cooling. Very quite and decent power usage. Its a great respite for heated Summers. It has different mode of operations depending upon requirements. The energy mode is a big plus. Servicing requirements are minimal and can be easily cleaned by self.
It has anti bacterial filter. Energy efficiency ratio is 2.60 which is very good.
