Never ever buy Arctic Air-little cooling box. working with 600ml water. is empty after less than 4 1/2 hours.
still have 29.5 C indoors after 4 1/2 hours-windows were closed all day.
And its loud-level 2 better bearable- at highest level 3. its like a fan when nearby you. Level1 is quite quiet but has little blowing effect.
8x4m room. was very hot around 35C outdoors in shadow.
