I've been using this dehumidifier for about a month. My basement is about 1,300 sq feet and can be extremely humid mid-summer. When I first turned the unit on the humidity level was 70%. The unit is surprisingly quiet about the sound level of a good size fan but most importantly the air that it puts out is cool. My previous dehumidifier gave off a lot of heat and other models I looked at clearly stated they blow hot air. This was very important to me which is why I'm glad I purchased this one. I almost gave it 4-stars since it runs quite a bit to keep the humidity down to 45% but it was my decision to purchase this size. However, if you have a basement the size of mine or larger I would purchase the 50 pint capacity unit. [This review was collected as part of a promotion.]
