Nice little dehumidifier

First of all, he's great! The dehumidifier is small in size, light in weight, and has two handles for easy handling. We use it in the basement, where the absorbed water is discharged directly through the hose, which is very convenient.

We purchased this dehumidifier to replace our last dehumidifier that was not working. I have never heard of this brand, but I like the specifications and performance of this device, and we are very satisfied with it. It takes up less space than the previous one and is very quiet! It has been working in the basement for several months, and the humidity level has been kept in a comfortable zone. I also like that it will automatically shut down when the humidity level is reached. Recommended!

We researched some basement dehumidifiers and finally purchased this unit. We are very satisfied with this purchase and recommend it to others.

I have been using this dehumidifier for several months. It's easy to set up. I would be happy to use the included drain hose to drain it into my sinkhole.
