Keeps my Basement Humidity in Check

Just put in a large rec room in my basement. No issues thus far.

A lot of dripping water due to the hot temps outside and the air conditioner working so hard inside, the ventilation pipes in the basement are dripping. But since we've installed the unit, we've had no moisture whatsoever in the basement. I'm very pleased with it. Humidity readout is really helpful.
Fantastic For The New Basement

We live in the very humid state of South. and we battle humidity year-round. It took a long time to buy this, and the machine is running without any noise. Very good, this is really good, the pumping volume is large, the effect is obvious, very practical, simple operation, high-power dehumidifier, really good!
Very good. Very satisfactory!

This sentinel HD55 basement dehumidifier is my second dehumidifier, and I love it so much, I think I finally found one. This is the best effect dehumidifier I've ever seen. It is a surprisingly real large amount of desiccant and is super quiet. I placed it nearby my basement, it really works just great! Unpleasant humidity is completely gone, it’s so amazing! There was one thing I worried about, it was its’ color does not tolerate dirt, but I think that it’s perfect for one basement / one room with moderately damp.
This thing works like a champ as far and is relatively small

Great! This dehumidifier is working hard in our damp basement right now. Most of our basement is finished, but with a long history, gets mold all over it. I think is because sweating pipes and moisture in the walls. Not exactly sure. Just know that having a dehumidifier running all summer has been our solution for now.
