Excellent product

This Alorair 90 pint dehumidifier can sense changes in humidity levels. We have a double storey house, we put it in the wettest place downstairs and use the remote control to adjust the dehumidifier settings. It also has some other powerful features, in short, worth every penny.
I hope it can be better

We are not satisfied with this dehumidifier! It has many modern functions, such as detecting humidity changes, air filtration, remote control, etc. Its drainage method is gravity drainage, but for some reason, I hope it can drain through the condensate pump.

By 'Serenity Holden', Reviewed on 2020-04-25 15:12:41
I changed a big house, but the basement is relatively wet, so I bought a dehumidifier to solve the humidity problem. AlorAir® Sentinel HD90 is my first dehumidifier and I am very satisfied with it. I was surprised that the water tank was almost full on the first day, and I inserted a hose to drain the water. And it runs very quietly.
long-term use

This AlorAir® Sentinel HD90 dehumidifier is impressive. After 2 years of use, this machine still looks good. Despite the 5-year warranty, I think it can be used for a long time. It can be easily disassembled within one minute for easy maintenance and repair.
So far so good
By 'Kajetan Puckett', Reviewed on 2020-04-17 08:57:28
This is the Sentinel HD90 model. This unit has been in service for a week. Since the device has reached the humidity level I chose, it can only be operated intermittently to maintain a low humidity. If there are any problems with the dehumidifier, I will update this review (although I do n’t want to do so), but so far, I really like this product.
