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

Powerful dehumidifier
By 'Samera Knights', Reviewed on December 27, 2020
It doesn't sound at all. Much quieter than my previous dehumidifier. It is very good, it can suck water from the air and make my basement dry. Don't worry about the price, you will get everything you need to pay, and I have never regretted my purchase once. I have been using it for 6 months and it will remain strong even if I use it almost constantly.
We like it!
By 'Nadeem Benitez', Reviewed on December 20, 2020
This 90-pint dehumidifier did meet my expectations. Before buying, I did a lot of research and found that this is exactly what we need. We use it in the basement, which can maintain humidity well. I started storing some wood and some books without worrying about mold. recommended!!!
Good performance and easy to set up
By 'Yazmin Dejesus', Reviewed on December 13, 2020
The Sentinel HD90 dehumidifier can remove moisture quietly. Very quiet during operation. good results. It is very simple to set up and use. It can move the air easily. And you don't need to empty the water tank. Very suitable for basements and crawl spaces. Overall, it is highly recommended.
Great value
By 'Ronny Ratliff', Reviewed on December 06, 2020
This dehumidifier works well. Since there is only gravity drainage (no pump), I had to place the dehumidifier above the drainage connection. I like the transparent tube, so you can see the water flowing. I can check to make sure it works.
Efficient and quiet, get the job done!
By 'Eddison Chapman', Reviewed on November 29, 2020
Bought a new house and there are some minor water problems in the basement. This dehumidifier did an excellent job of drying out my basement. It is small, powerful, and quiet. Excellent dehumidifier, high quality, it is very good to use in the basement. So far very impressive.
Every penny is worth it.
By 'Hira Pratt', Reviewed on November 22, 2020
Before getting the product, I first read all the reviews. The installation is very easy, within 10 hours, it absorbs a lot of moisture from the air. Now, whenever the humidity exceeds 45, my dehumidifier turns on and sucks water from the air. This is a great product. I like it so much.
A quiet and efficient unit
By 'Mahdi Butler', Reviewed on November 15, 2020
I bought this equipment to replace a malfunctioning dehumidifier in a 2,300 square foot basement, and will never be happy again. At first, I was worried because the device did not have a pump, but the hose was easily connected and the device started to work. The hose is sufficient to drain the water, use a bucket to collect the water. It has been working for about two weeks, which is great! ! I can feel the changes in the air, and make me realize that this unit is much better than any unit I have tried.
Great product and company!
By 'Marina Leal', Reviewed on November 08, 2020
I bought this product and worked exactly as described-very effectively reducing the humidity of the air in the basement of our children's finished product. A hose attachment was used to drain and it worked well. After a period of use, the machine malfunctioned. I emailed it to customer service and they are happy to deal with customers. Quick, professional, friendly, and helpful. Amazing customer service. I cannot give enough evaluation of this company. Of course, I will buy from them again and highly recommend any items you consider buying.
Excellent dehumidifier in the basement
By 'Carmen Mcpherson', Reviewed on November 01, 2020
I have done a lot of research on this and it has been running for about 2 weeks now. I am very happy. It can be turned on and off as needed. It runs very quietly. I like the continuous drain hose function. In general, I am very satisfied with this dehumidifier. It looks good, saves space, and can be moved well, and the controls are intuitive. I like the humidity display.
good results
By 'Zoha Kim', Reviewed on October 25, 2020
I purchased this product to replace the equipment with a drainage failure. The device drains directly into the main air conditioning drain through gravity drainage. It can reduce the humidity in the area where I store books. The average humidity drops from 60-70% to 40%. Love this unit.

How to drain the water?

Courteney on March 29, 2021

1 Answer

Answered by Alorair
For effective drainage, lead the drain pipe into the pit. Check to make sure it is flowing downwards, and there should be no troughs, sinks, or loops. You can use PVC pipes to draw the water out. The machine drains under gravity, so make sure to completely defrost it when storing it.
