This is the first dehumidifier in the true sense that I have, and this is the most praised humidity control unit. It works and is very quiet! The dehumidifier products I bought before for less than $100 did not work. For consumers, this is deceiving. Don't try to buy cheap and inferior products cheaply, but buy products that can be used.
Ideal for basement
By 'Usman Parker ', Reviewed on 2020-06-22 18:53:16
Due to the arrival of summer, our basement is poorly ventilated, so the air humidity is particularly high. We used to use the same dehumidifier to solve the problem, and this time is no exception. AlorAir® Sentinel HD55 can effectively reduce humidity and remove at least 55 pints of water every day, making it ideal for basement spaces.
Quiet operation

I am happy to buy the Sentinel HD55 dehumidifier. We used to buy a dehumidifier on Amazon, but that model is inefficient and makes a lot of noise. Sentinel HD55 runs quietly and can dehumidify within 1,300 square feet. For us, this is the best choice.

AlorAir® Sentinel HD55 exceeded my expectations! It has passed multiple quality certifications, so I don't have to worry about its durability. It is worth noting that it has an air duct option for dehumidification, and it can be controlled remotely through remote control.

My dehumidification equipment is old and cannot start to operate normally, so I need a new dehumidifier to keep the basement air dry. I think this unit is worth it. It runs quietly and can operate at low temperatures. Consumer Reports listed it as an Energy Star, a great product.

I don't know, my basement is leaking and a large area is soaked. Experts brought this compact dehumidifier for repair work. It extracts water from the air to reduce the humidity level. It ’s really easy to use, and I ’m thinking about whether I should buy it myself so that it ’s needed when it ’s needed.
