Review after 5 years of use......
The best AC i have ever seen. I already have two different ac's on my home and none of them work as this. First it is ultra silent.... you can't hear anything..... The consumption of energy is 0,4kw. I usually set fan to lowest and the temp on summer to 25c. Also the auto cleaning process do what promiss.....after turn off the unit, it keep on the fan motor until get dry.
