Quiet and energy-saving
By 'Philippa Hall ', Reviewed on 2020-04-28 09:42:27
I bought this model dehumidifier and installed it in the underground storage area, the operation is very quiet. I know quiet is a relative term, but this is much quieter than my previous model. Moreover, it consumes less energy and does not need to pay high electricity bills.
Suitable for small families

I encountered water problems in the basement and it was moldy. To solve this problem, I called an experienced expert who quickly installed this 55-pint Sentinel HD55, and in a short time the basement was the driest ever, actually a few degrees warmer than usual, The musty smell disappeared.
I like this dehumidifier
By 'Carley Allison ', Reviewed on 2020-04-10 08:11:39
I live in Texas ... it often rains here, so my basement is really damp. Actually, I have a humidity sensor in the basement, so I know that the humidity stays above 80% for a few months. I bought this AlorAir® Sentinel HD55 dehumidifier and made it work within a few minutes. I have worked it for one day according to the instructions in the manual, and the humidity has dropped to about 50% within 24 hours. I like this thing.

I live in a small apartment in a very humid climate. At night, I use this machine in my bedroom for 6-7 hours while sleeping. The machine works great in making my bedroom more comfortable.

This AlorAir®Sentinel HD55 has helped enormously to decrease the humidity and water in our basement. Most probably this is the best dehumidifier that I have ever purchased. It keeps the humidity within 50% percent of where it is set at. It runs quiet also. Very happy, and I hope it will last longer than I expect.
