I purchased this dehumidifier for mainly basement use, but wanted one quiet enough for use upstairs if needed. And, boy is this thing quiet. My refrigerator is louder. I also own a Fedders 45 pint unit and a Whirlpool 65 pint noise maker. The Fedders (Maytag) was the quiet champ until I purchased the Soleus Air CFM-40E. The Whirlpool removes an amazing amount of water, but can be heard UPSTAIRS when running in the basement. So it is used only when needed. The Soleus Air is so quiet I have to go down the basement stairs and visually check to see if the unit is on. Can’t say that for many dehumidifiers. My only complaint is that the fan is always on, even when it has reached the set humidity level. This prevents the short cycling the others do, on for 2 minutes off for 2 minutes or so, but I think prevents an Energy Star certification. At 2.9 amps it draws significantly less than the Fedders 5.6 amps and the Whirlpool’s 7.9 amps.
The Soleus Air works great upstairs in the spring, when it is cool but damp. The weather this week is in the 60′s but rainy, so the house is humid. Running the central air is not necessary since the house is not hot. So I use a dehumidifier, which makes the house seem less clammy. I would recommend the Soleus Air CFM-40E to anyone who is looking for a small, really quiet, relatively light, medium capacity (40 pint) dehumidifier that simply does what is supposed to do (remove water from air) with out excess noise.
