    Customer Reviews

    Based on 16 reviews

    We bought an obnoxious damp house, A basement infested with mold. The smell was so bad that I couldn't walk down to the basement without having an asthma attack. We bought this dehumidifier and it says it's 96 percent moisture. I thought it wasn't true, wasn't it raining? But I quickly discovered that, yes, this level is accurate. We use automatic drain hoses, which is very convenient. Then, even in heavy rain, the moisture starts to drop to 70/60 percent. I finally made some ground improvements and better sealed the basement, and after six weeks, the dehumidifier kept the moisture content at 42 percent. The smell was about 95 percent gone, and I was actually able to enter the basement painlessly. This dehumidifier is amazing. Work very efficiently!


    I am happy to have found this particular model because it has the features that I wanted for a price that I can afford. As you can see my office is in the ENTIRE basement. The dehumidifier is stylish and fits right in with my office layout. The controls are easy to understand. But just plug it in and turn it on. It just works. I had it on a few minutes and already see that it had started to collect water from the air already. I’m going to just leave it on in Continuous mode and dump the water canister when it’s full. The water canister is in the front so it’s easy to access and pull out. There is an option to run a drainage hose out the back of the machine.


    It is very quiet and efficient. Easy to install anywhere. The drain pipe is not very long, so it is restricted when used. I use it in the basement. Surprised how much moisture this machine absorbs from the air! I am very satisfied with this product and would definitely recommend it. We have not encountered any problems. I will buy this model/brand again.


    This dehumidifier does a very good job of keeping the small basement dry! Compared with our previous ones, it is so small, compact and quiet, which surprised me. This unit has been working in the basement for several months, and our basement no longer smells of humidity! Highly recommend!


    Excellent quality, very compact and quiet. I purchased this product based on all reviews. I have been running this dehumidifier in the basement for several months and it helps to keep the entire basement (about 900 square feet) of moisture. I am very happy about this. I am very satisfied with my purchase and would recommend it to others.
