It's the Best Dehumidifier!!!!

It was getting Really Humid!!! It works So Well that the Basement now feels Less Humid then the House!!!
First Time AlorAir Dehumidifier Buyer
By 'Issa Goddard ', Reviewed on 2019-08-26 09:34:20
We have a damp basement. After reading many reviews on-line about dehumidifiers, I decided to buy the AlorAir 55 pints dehumidifier for our basement based on a large number of positive reviews. It drains well through a connected hose to the sink as it sits up high in the basement. It is not too noisy which I also like. But I have a slight concern about the life expectancy of the unit after reading several reviews about the unit only working for one year. For now, I am very happy with the purchase and I am considering ordering another unit for my downstairs.
Awesome cutomer service

Have used this product for 3 days. It seems to be working very well. Directions and customer service are the cause of the five stars rating. Regina is a dehumidifier professional. I asked many questions and she was very patient to answer them. She is very helpful. I also put insecticide in the bucket that collected the water so that it didn't become a breeding ground for mosquitoes in the dark, damp basement.
This unit really works great.

We liked the looks of the Sentinel HD55 unit because the design appeared to be much like our old GE unit. It's also a reasonably quiet unit. The Sentinel HD55 works just fine from the standpoint of dehumidification.
Does the job plus but

Nice feature. Excellent unit. It does the job well, is attractive and the cost is in line with the product, though it's a bit expensive.

I WILL BUY THIS BRAND AGAIN! This 55-pint dehumidifier is exceptionally efficient, pulling moisture out of the air even when there are heavy rains outdoors. We have had numerous dehumidifiers for our basement, where we keep several bookshelves of books that would deteriorate in high humidity. Recommend this unit HIGHLY. Easy to set up; filter access is easy.
Good features

This seven-gallon dehumidifier seems to be working well.
Excellent model(55Pints)
By 'Kenneth Dunlap ', Reviewed on 2019-06-24 12:03:45
We purchased the 50-pint model. Excellent features. Works great! On continuous mode, it automatically dehumidifies it reached the humidity level you set and stops dehumidifying (including fan). Then it waits till the humidity exceeds your level and starts dehumidifier again.
 It's a great dehumidifier!

I'm a mushroom grower in Oklahoma & I've had a hard time controlling humidity in the shipping warehouse. I don't want the mushrooms to go rotten or moldy in such a short time before shipment. It worked great, it got the humidity I needed, It puts off the heat on the right side of the dehumidifier so I can adjust my the temp in the warehouse. It's a great dehumidifier! No complaints as of yet!
Good dehumidifier and service
By 'Gerald Villarreal ', Reviewed on 2019-06-13 09:52:04
This unit does a really good job! To give you an idea of how horrible my moisture problem was in our basement, water would be pooling on the windowsill and dripping on the floor every morning. I bought this Sentinel 55 dehumidifier pints Not a problem this morning.
