Excellent to keep the basement dry
By 'Anaiya Prosser', Reviewed on February 01, 2021
We researched some basement dehumidifiers and finally purchased this unit. We are very satisfied with this purchase and recommend it to others. We give it 5 stars because it is much better than our last dehumidifier. Our finished basement is moderately humid, and I don’t want my furniture and floors to get damp and suffer damage. We are very satisfied with this device because it keeps everything dry and eliminates the musty smell by using it.
Very effective and reliable
By 'Bianca Sanford', Reviewed on January 25, 2021
I have been using this dehumidifier for several months. It's easy to set up. I would be happy to use the included drain hose to drain it into my sinkhole. Although the size of this dehumidifier is much larger than my previous dehumidifier, it looks better. I happen to use it in the crawl space, but it looks good and quiet, so far, there are no problems, very happy!
Excellent to keep the house dry
By 'James Millar', Reviewed on January 18, 2021
This machine is great! Works miraculously! When we first started using it, the humidity in our house exceeded 80%! Since we started using it, we have noticed that the house is very different, it no longer has a moldy smell and smells fresher and drier. If you encounter humidity problems in a larger house area, it is strongly recommended to buy this product.
Play a role in our damp basement
By 'Gabija Hagan', Reviewed on January 11, 2021
It only took a short time, but so far it is bringing the humidity in our damp basement to acceptable levels. It is relatively quiet and easy to disassemble and clean. We have a drain hose hanging on it, so we don't have to remove and empty the container. It looks like it will serve us well, and we have just received a 5-year extended warranty, thus increasing our confidence in the quality of the equipment.
Works well
By 'Bentley Sykes', Reviewed on January 04, 2021
We put this dehumidifier in our basement, some seasons tend to smell musty. Our house is relatively old and it is difficult to prevent the accumulation of moisture in the basement. We can tell the difference in the atmosphere in the basement within 24 hours. We have central air, and sometimes the smell of the basement comes out through the vents, and now the dehumidifier is running, and nothing is noticed upstairs. We would recommend this product to anyone who encounters such problems. It performs best among all the dehumidifiers we have.
Good dehumidifier
By 'Montell Carrillo', Reviewed on December 28, 2020
We live in a high-humidity climate and need something that can dehumidify and accurately measure humidity. The dehumidifier can accomplish this job. It drew too much water from the air and we felt better. We used to have only $70 dehumidifiers in our bathrooms and laundry rooms, they were so fragile and useless. It is definitely worth it to spend money and get a good one.
Great commercial product!
By 'Tyreece Escobar', Reviewed on December 21, 2020
The air in my basement cannot circulate, which makes the space very humid. My friend recommended this dehumidifier to solve the humidity problem. I was skeptical at first, I thought it was not as good as the comments said. But after using it, my opinion has completely changed. It exceeded my expectations. It is not only fully functional but also has a high capacity, which is worth the money.
So far, I am very satisfied
By 'Theia Sheehan', Reviewed on December 14, 2020
We stored some books, fitness equipment, and some wooden furniture in the basement. Usually, we rarely stay in the basement. Unfortunately, the basement seems to be moldy. Humidity has reached an unprecedented level of more than 70%. We had to use a dehumidifier and put it in the basement for work. This one left a deep impression on me, it can automatically detect changes in humidity level and automatically turn on to lower the humidity level. The basement is more comfortable than before, and now we seem to spend more time in the basement.
Great product
By 'Catrina Cruz', Reviewed on December 07, 2020
We need to decorate the basement. In order to make the basement dry quickly, I discussed various options with my family and finally decided to use a dehumidifier for drying. This is an excellent device to prevent damage and overheating, and surprisingly, it is equipped with an air purification filter, which is perfect for our basement.
The best dehumidifier I bought
By 'Tonisha Bradley', Reviewed on November 30, 2020
This is the main force in our basement. So far, everything is great. The amount of water this thing absorbs from the air is amazing. Compared with other units I bought in the past, this unit is quiet. It is simple to use and requires no complicated instructions or maintenance. I like it very much and would definitely recommend it.
