Automatic Defrost: Our advanced auto-defrosting system continuously monitors the ambient temperature using built-in sensors. When the temperature is detected to be low, the unit initiates an automatic defrost cycle to prevent frost buildup and related issues.

This feature conserves energy and helps extend the lifespan of the unit

Easy to use, get the job done!
By 'Patsy Fields', Reviewed on March 14, 2021
The air was immediately dehumidified on the first day of arrival. My basement smelled much better after a few days! The machine itself is not as loud as other dehumidifiers I have heard, but it does make some noise. It is easy to operate, it has only a few buttons, I only set it once, and it has been running for me for several weeks without any adjustments. So far, so good! This is a high-quality product and definitely worth the money.
Good product! Compact and quiet
By 'Ashraf Chan', Reviewed on March 08, 2021
So far, so good. It works normally, runs quietly and drains well. It keeps our basement dry and we are happy to find this product because there are not many sophisticated dehumidifiers on the market today. If you need a good dehumidifier, this is a good choice! I would recommend this brand and model!
Amazing product, quiet, efficient and easy to use!
By 'Yash Soto', Reviewed on March 01, 2021
The product is very good and works as expected. This dehumidifier can definitely take away the moisture in the air in the basement. Once it reaches the humidity level I selected, it will shut down and continue to work when the humidity changes. It is compact, quiet and easy to set up. If you need a dehumidifier, it is definitely worth it.
I highly recommend this product!
By 'Felicity Hogan', Reviewed on February 21, 2021
We recently purchased it and it has been working well so far. It is very easy to install, especially with a drain hose. We are worried that it may be too small for our basement, but it has reduced the humidity in our basement, and we can feel the obvious difference.
Amazing dehumidifier!
By 'Lena Acosta', Reviewed on February 06, 2021
This is really an amazing dehumidifier, it works very well, it is very quiet, the device is not too bulky and easy to use. We use it in the basement to control the humidity there and connect the supplied hose for automatic drainage. It has been in existence for several months and can maintain humidity at around 50% without problems. I highly recommend this product.
Satisfied with our purchase
By 'Charlize Morton', Reviewed on January 31, 2021
This is an effective dehumidifier, suitable for our basements above 2000 square feet. We have been using it for more than two months, essentially plugging it in and forgetting it. It has reduced the humidity to a comfortable level, which greatly reduces the musty smell. The noise level is so small that we don't pay much attention. If needed, I will buy it again.
The product is very effective
By 'Elsie Wagner', Reviewed on January 24, 2021
The product really works. I use it in a basement where the air is very humid and full of moisture. My office is in the basement and I stay there most of the time. When I realized that the office was humid, I decided to buy a dehumidifier. I read a lot of reviews and finally ordered the product. I am very happy. Since using this product, the air is obviously less humid and the environment is more comfortable. The dehumidifier does not take up much space and is very easy to install and use. It does not make a lot of noise, I just hope to buy it sooner. I would recommend it to anyone.
Well-made dehumidifier
By 'Wasim Wood', Reviewed on January 17, 2021
After noticing the mold, we purchased this unit for the basement. We have conducted a lot of research and found that this is in line with our needs and price point. We are very satisfied with the purchase. We used it in a finished basement with an area of 1,800 square feet, and the amount of water pumped out far exceeded our expectations. The smell and musty smell disappeared. Glad we purchased this equipment.
Do this job
By 'Hisham Bright', Reviewed on January 10, 2021
We use it in basements with high humidity. The difference on the second day is huge. I connected the drainpipe to the floor drain with a hose and kept pouring water into it. I know there is some moisture in the basement, but I don't know how much until I use it. The device is quiet and very easy to use and move. Value for money.
Really efficient
By 'Reuben Downs', Reviewed on January 03, 2021
I absolutely love this dehumidifier! It can reduce the humidity in my basement from 70% to 50%! Very quiet and easy to operate. I let it work in continuous mode, connect the hose and drain water continuously. I like the coil defrost function, which makes it work properly at low temperatures.

Is the pump disposing of the collected humidity from the space or the condensation from the compressor?

The evaporator drains moisture into the pump, which drains moisture out of the unit. The pump helps to lift the water up to 5 meters if you are draining upwards.

The air is sucked into the unit from the front panel (black) and blown out on the right side. You need to ensure that the unit has good air following conditions, and the air follows smoothly without being stuck.
