We went to visit a friend on a hot day and surprisingly we were very comfortable in his place. We then realised he had a Dyson Pure Cool working in the corner. We hadn't noticed it, it wasn't loud or bulky, and it made the environment very comfortable. We went back to our house, which was really warm, and decided spending the money on this was worth it. We do not regret the decision. And it works as an air purifier too, an added bonus.
