Although noisy Speed 2 we do not experience noise annoyance as our main use is in the basement. We are satisfied with this dehumidifier. It is effective .. For greater ease of use we installed a discharge tube in half a day because the ferry was already full. By cons in residential noise could be annoying. I recommend it for parts such as a basement, garage, laundry (what the surface is less compared to its capacity by area). With him ended musty odors and moisture. Easy to use.
