Excellent dehumidifier
By 'Lyndsey Drummond', Reviewed on November 02, 2020
We ordered this dehumidifier to replace our previous dehumidifier. The dehumidifier is still working, and the sound is not loud, and it cannot be heard upstairs. We are very satisfied with this. It takes up less space than the previous one and is very quiet! We have been there for a few months and found it great. I also like that it will automatically shut down when the humidity level is reached.
Just what we need in the basement!
By 'Osian Woodward', Reviewed on October 26, 2020
We bought this dehumidifier for the basement-about 3,000 square feet, open space-it has been buzzing since then and it is easy to keep the relative humidity in the 50% range. I connected the drain hose and drained it through the pump, so I don't need to empty it every day-very fast and convenient. This quiet and efficient dehumidifier definitely makes me happy.
Worth investing
By 'Herbert Bostock', Reviewed on October 23, 2020
Used in the basement residential area of the house for more than a month. There is a lot of moisture there, and this device can control the humidity in the underground area. I raised and installed my equipment on a shelf, keeping a proper distance from the wall, and using the provided hose to drain water. When I set the humidity to 40%, it can indeed operate normally. I am very satisfied with this equipment.
By 'Spike Hartman', Reviewed on October 19, 2020
I have read a few reviews before purchasing this device. It's easy to set up and work according to the instructions. When we purchased the equipment, the humidity level on the first floor was 70%, but now it is about 40%. We are very satisfied with this.
In less than a day, the basement smelled fresh and dry!
By 'Alara Goddard', Reviewed on October 15, 2020
It's easy to set up, and so far, it does do what we need to do. It has a pump, so it is in continuous mode and takes care of a problem that we have been waiting for a long time to solve... the wet basement. The price is also great. Hope it will last a long time.
Very powerful machine
By 'Linzi Fellows', Reviewed on October 12, 2020
This dehumidifier is working hard in my damp basement. Most of our basements have been completed, but we found plaques on the dry walls, where mold grew, I think this was due to sweating from the pipes and moisture on the walls. uncertain. Just know that running a dehumidifier has become our solution so far.
So far, a good machine
By 'Rees Brandt', Reviewed on October 05, 2020
Put it in my basement (3000 square feet) to reduce moisture. The machine is heavy and strong. I ordered a hose and connected the machine to the drain, so there is no need to empty the water tank. The humidity in the basement is about 75 to 80 and it is now 45. I realized that there has been no mold growth since the recent cleaning. Happy with the result.
Great dehumidifier!
By 'Hal Waller', Reviewed on September 28, 2020
Overall a great product. Extract a lot of moisture from the air. I run it a lot and we live in Florida, so it is almost impossible to keep the humidity at the proper level at this time of the year. Using this product, even in the case of using AC, the indoor humidity can be reduced to about 45%, good value for money!
Very efficient! Very satisfied with the result
By 'Riyad Dixon', Reviewed on September 21, 2020
We have experienced a hurricane, so we are going to dry some rooms, Sentinel HDi120 works well! Obtaining a lot of water from the air, it can be easily moved from one room to another. If you suffer from a storm like me, please don't wait, it's definitely worth the money!
Really remove moisture from the air
By 'Lillia Foreman', Reviewed on September 14, 2020
We put this dehumidifier in the basement, and it often smells of musty in autumn. Our house is relatively old and it is difficult to prevent the accumulation of moisture in the basement. Sometimes the smell of the basement came out through the vents, and now the dehumidifier started to operate, and nothing was noticed upstairs. We would recommend this product to anyone who encounters such problems. It performs best among all the dehumidifiers we have.
