Works but has some flaws
By 'Kyra Lisa Duarte', Reviewed on 2019-08-13 18:59:33
My husband has had this in operation for two weeks. Sentinel HDi90 Dehumidifier is quiet and it is removing water vapor far better than our previous unit. However, we do question whether it is operating properly. We will hope to contact a tech person familiar with the proper sequence of operation. I turned it off when I wasn't using it, but the fan kept turning, which is normal, because it stopped after a while, but the machine didn't drain out. I asked the after-sales service and he said it was normal. I do not know at this point but I question whether this is proper operation. Time will tell, I need to get an answer.
Does the job. Saved my basement

Wonderful!About 2 months ago, I bought a house with a 1000 sq ft somewhat finished basement. And I bought this HD90i dehumidifier with 5 years warranty as the lifespan of dehumidifiers seems to be limited based on reviews of ALL brands on line and this unit will be used 24/7. In no time it was delivered to my home. But here's the best part... the air is fresh and sweet. It's unbelievable. Now I feel like I just opened up a huge addition to my house which before, I could not bear to enter.
Overall I'm satisfied.

Easy to use. As for dehumidifier's intelligent, I have had it work for a month very nicely.

In the summer, it gets very humid and my AC unit works overtime to cool and dehumidify. This little guy works wonders as a whole house unit when centrally located or as a spot dehumidifier in the kitchen when I'm cooking.
I’m very happy with this item and communication with seller

When I had condensation on my windows on our underground garage which I take to mean too much moisture in my house. I bought this to put in. My wife thought I was crazy saying it wouldn't even draw any water out of the air. Now, a lot of water comes out every day. My wife has now told me to order another one for the basement. lol
We don’t have any more problems with mold or corrosion.

You CAN dehumidify a 4-car garage with this unit. The drainage seems a little slow but it does its job well. Smooth running. I recommend this product.
Great product at a great price

This Sentinel HDi90 dehumidifier did an amazing job! We live in a very humid place. The room never felt particularly wet, but it does feel warmer now. It's so easy to use. A very low unobtrusive buzz.
Does work well for basement

After having used this for two weeks, I honestly tell it's made a huge difference between when I use this and when I don't. Look at the amount of water! This is definitely worth every penny!
