I got this fan 3 days ago, and I can "warmly" (cooled) ;-) recommend !!! I have a 30 sqm apt and my room plus hall is controlled to a very comfortable temperature down. Geräuschemfpindlichkeit describes each individually !! He makes ordinary quiet fans noise means that if you are used to sleeping with a car noise, or a TV, the fan should interfere at level 1-2 no one while sleeping. So I can sleep wonderfully :-) and my cats even enjoy it, not run away even when I unpacked and connected him !! Stage 3 is a bit loud, but not annoying, watch TV thus is not a problem !! If you, however, is used should sleep without any noise is in my opinion completely dispense with a fan in the bedroom. As every fan noise is of itself! The structure is also very easy and it is no plastic smell of it !! I would buy myself this fan repeatedly !! Everything Tippi Toppi !!
