Review Title: ADS-400 Mini Dehumidifier

Comments: It wasn't very powerful, though was quiet. I bought it to bring the low humidity in a low-temperature wood-drying kiln. It wasn't strong enough. The wood part of the kiln is around 3.8 feet x 3.8 feet times about 7 feet. The box has insulation all around it and a very slow steady wind, but it was 60% humidity when I put it in, and still about the same four hours earlier. I'm not sure what I can use it for, maybe something will turn up.

Review Title: NewAir ADS-400 Mini Dehumidifier
Comments: I use the NewAir ADS-400 in a 10' x 10' room. I asked before purchasing if the product would work for a room of these dimensions. I was told yes. It works, but just not good enough. I would return it but, I've thrown out the box it came in. It may be good for a closet, but not a room any larger.

Review Title: Dehumidifier
Comments: This humidifier is very quiet but also very ineffective in a small bedroom. After 36 hrs, only about 3 tablespoons of water on a very muggy, Florida day. Didn't change the humidity in the bedroom at all.

Comments: This is a good value. It's small, relatively quiet (small hum), and easily fits in a corner. We have a very small, unvented bathroom that gets a lot of shower use when the kids are home for the summer. This unit helps to keep the moisture at bay, thus preventing an annual breakout of mold.

Review Title: Great for boat environment
Comments: We keep this running 24/7 in our aft cabin of our boat - we live aboard - and it has kept that space dry. Very quiet - we can sleep with it on. After a couple of months it keeps on working. So far so good.

Comments: We are using in our cabin on the boat. Over the winter while the A/C was off the furniture and carpeting was very damp. A large unit is impossible. While it may take sometime to dry out completely, it's drawing 4 ounces per day as stated. Overtime, it will be perfect for our boat!!

Comments: It works very well - I live in a very foggy area. Moisture and mildew are a common problem. I was amazed how much moisture in pulled out of the air in my closet. The cost of the unit is well worth it.

Comments: The product works great! As promised, it is quiet. It has made a huge difference in our bedroom! Previously our carpet always felt damp when walking on it. Now, the dampness is gone and it is very rewarding to see how much water the dehumidifier is taking out of our air!
