I will buy it again
By 'Riaz Werner ', Reviewed on 2020-11-30 10:31:31
This thing is great! My basement is damp and needs to be quickly dehumidified because it promotes the growth of mold. I got this ENERGY STAR certified product, and it came a day earlier! I placed it in a suitable place and connected a drain hose for gravity drainage, which worked very well. I will buy it again.
Great! The musty basement smell is gone!

In November, our rainfall increased, the sewage pump was never shut down, and the basement smelled of musty. The Sentinel HD55 dehumidifier is delivered quickly and is simple to set up. There is a dehumidifier in the entire basement and the smell disappeared! It only took 1 month, so I can't talk about durability. So far, I am very satisfied with the dehumidifier. It is quiet and efficient.
Working well

This is the second one we purchased. Can keep the humidity down well. I ran this in the basement. I set it to the desired humidity percentage and turn it on and off as needed to maintain that level. I also installed a clean hose to keep draining water as needed.
Help remove moisture in the basement
By 'Henri Roach ', Reviewed on 2020-11-09 10:48:15
Living in Maryland, the humidity there is tiresome. Purchased this dehumidifier for our approximately 1,000 square foot basement. It removes most of the moisture and maintains the humidity level. It is not the quietest device, but as someone who is sensitive to certain noises, I do find the fan here is very soothing and stable. The noise does not propagate upward from the basement, so don’t worry about it disturbing you. To be honest, I don't know how to rate "energy efficiency", but what I want to say is that I haven't seen any significant increase in electricity bills, so I do believe this is an energy-saving device. I really recommend this machine.
Excellent dehumidifier

The first dehumidifier I own. The operation is very simple. It can remove moisture in my basement and prevent moisture from accumulating on the walls. I like that they come with a drain hose so I can drain the equipment directly to the drain. In short, it is an awesome unit. Easy to move and quiet. It is strongly recommended to use in humid places.
Lightweight and quiet

I have a three-room apartment. This dehumidifier is very suitable for the size of our house. It can quickly remove moisture. I can see it because it is quiet enough to stay in the room. The product is lightweight and easy to move, I like it. This is my best gift to myself!
It works well. very happy
By 'Ethel East ', Reviewed on 2020-10-19 10:00:19
In fact, this is our second. The first one had an accident during transportation and we had to replace it. We started it as soon as we received this device. We like to use a hose and drain it directly into the drain by gravity drainage. They have been running since I started them. They keep things comfortable and the moisture does not drop. They are working at maximum capacity.
Easy to use, get the job done!

I bought this dehumidifier for my basement, and it is humid all year round, especially in the warm season. I like to set the humidity level to 45. I compared it with some other devices and it seems that its size is slightly smaller. It looks great and adds a modern touch to the room. What I appreciate most is that it is easy to operate. It only has a few buttons, I only set it once, and it has been running for me for several weeks without any adjustments. It is very simple and recommended for homeowners!
Keep my basement dry
By 'Marwa Stevenson ', Reviewed on 2020-10-05 08:52:45
Dehumidify the air immediately on the first day the product arrives. My basement smells so much better! I poured 55 pints of water the next day. The machine itself is not as loud as other dehumidifiers I have heard, but it does make some noises, but if you are in a room, you cannot hear it from below. So far, everything is very good! This is a high-quality product and definitely worth the money.
Just what we need!  
By 'Pooja Beltran ', Reviewed on 2020-09-28 08:45:22
Great product, I thought our house was dry until my wife bought this dehumidifier. Put it in any room and you will see water draining from the hose, effectively eliminating the moisture in the air without generating annoying noise. like it!
