Automatic Defrost: Our advanced auto-defrosting system continuously monitors the ambient temperature using built-in sensors. When the temperature is detected to be low, the unit initiates an automatic defrost cycle to prevent frost buildup and related issues.

This feature conserves energy and helps extend the lifespan of the unit

Very please with dehumidification and size.
By 'Cortez', Reviewed on November 07, 2019
As a function for saving energy, the unit will completely turn off once it's reached its set point, only to immediately turn back on 2-4 mins later with a full compressor. My only complaint would be that there are no free replacement filters.
This dehumidifier is awesome, absolute best value if you want a 'beast of a dehumidifier'
By 'Elena', Reviewed on October 23, 2019
Absolutely amazing! My basement is unfinished and musty due to a high water table in my area. Now, when I go down to do laundry it smells so fresh. The factory did a great job. Highly recommended.
Perfect Size for a basement &crawl space dehumidifier

It has been functioning as it should and I am pleased with it. This is the first basement dehumidifier I have tried. Thanks, AlorAir, for a dehumidifier that is working right, so far.
Hard Working

Luckily I had purchased a 5-YEAR warranty and received a full refund for the original unit. Based on web reviews it appears all brands of dehumidifiers have a high failure rate after a few years of use. Although I am hoping the this new replacement dehumidifier will last a lot longer than original.
Good

This is the first 90 qt dehumidifier I have purchased. This unit drained into a sink. I have bought 70 qt dehumidifiers and they seems work samilier daily.
Very Nice Unit
By 'Marcie', Reviewed on September 10, 2019
I'm very happy with it. This Sentinel HD90 unit works so much better. We use this unit in our workshop that has gas radiant heat. The heater throws out a lot of moisture during the winter and the old dehumidifier we have would frost up on really cold days trying to keep up. But this unit keeps up without a problem.
Easy set up, Does what it says!

We live in the southeast with high humidity in the summer months. It seems the AlorAir® Sentinel HD90 Dehumidifier is working fine. It is easy to set up. I just do what it says. I think it may have some catching up to do as the humidity is still about 45% after a week. It has fluctuated. I would have thought it would have pulled more water than it has. I've only emptied the bucket twice. But now I attached the garden hose which is easier.
Sure A Workhorse! Would get another!

We got this model because of its high rating in customer reviews. This Sentinel HD90 dehumidifier has been working great in my basement for a long time. So far it's been great.
Excellent purchase!
By 'Abdul Davey', Reviewed on August 12, 2019
I live in humid TX and decided the 90pints dehu would help me smell better in the basement, it is helping. Here's the second part of the review. I've had the unit for a week. The unit is very quiet. In a quiet room, I can't hear it 2 feet away. Up closer you can hear air rushing through the vents.
It is more effective than our expected
By 'Jad Mustafa', Reviewed on July 24, 2019
We have a basement is moldy, musty smell, and stale air down there. Our big washer located there and so I make several trips downstairs every week. It does its job well! AlorAir delivered this item in record time ( I think 5 days) for a shipping cost. I was impressed since it weighs about 50 pounds with all of its boxes. Requires two people to remove from box as it has to be lifted vertically. The alternate for one person is being very cautious with a case cutter to slice the box corners without cutting too deep. Now I feel like I just opened up a huge addition to my house which before, I could not bear to enter.
