High Performance!
By 'Tyler Farmer', Reviewed on May 10, 2021
The HDi100 is a high performance dehumidifier, it has been keeping low humidity and low noise for my garage for two months now. So I decided to have one for my house. I still wanted something with a condensate pump so I didn't have to deal with draining canisters or buckets.
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!
