Proven Performance

The Sentinel SLGR 1400X dehumidifier has two stages of filtration for capturing mold spores, debris, dust, pet dander, pollen, allergens, and more. The first stage of filtration is a pre-filter that filters larger size debris and dust particles. Next, there is a MERV-10 filter that handles smaller sized particles. In cold, humid places, it can be tough to remove moisture completely. In these situations, you need a dehumidifier that has a powerful fan to keep dry air circulating at all times. The Sentinel SLGR 1400X can circulate 420 CFM of air. This makes it capable of maintaining areas up to 3,800 sq. ft The Sentinel SLGR 1400X dehumidifier has a large contact surface on the cooling coils, which means it can quickly cool down hot air, in addition to handling a higher air volume. The unit is also equipped with an automatic digital control system for easy setup and accurate operation.

Work very efficiently!
By 'Jillian Silva ', Reviewed on 2021-04-05 15:33:17
We bought an obnoxious damp house, A basement infested with mold. The smell was so bad that I couldn't walk down to the basement without having an asthma attack. We bought this dehumidifier and it says it's 96 percent moisture. I thought it wasn't true, wasn't it raining? But I quickly discovered that, yes, this level is accurate. We use automatic drain hoses, which is very convenient. Then, even in heavy rain, the moisture starts to drop to 70/60 percent. I finally made some ground improvements and better sealed the basement, and after six weeks, the dehumidifier kept the moisture content at 42 percent. The smell was about 95 percent gone, and I was actually able to enter the basement painlessly. This dehumidifier is amazing. Work very efficiently!
Amazing dehumidifier

I like to use this high-quality dehumidifier. When I received the product, the packaging was not damaged and all parts were intact. It is easy to operate and can do most of the work automatically. I just need to plug in the power, set the desired humidity level, and it will start to dehumidify. I have been using it in the basement and it has changed a lot. The air no longer smells moldy, and the walls are dry. I highly recommend this dehumidifier!
Run well, keep the laundry room dry

This unit did a good job of keeping my laundry room comfortable and dry. It greatly reduces the production of moisture, odor and mold. It's easy to use and has a powerful automatic drain function. We like it very much. Because it was in the laundry room, I didn't notice the sound at all during operation. Great product!
Good product

The Sentinel SLGR 1400X dehumidifier is great. I use it in the basement and it does an excellent job of reducing humidity. It has a hose connected to drain the water directly into the sewer, so there is no need to worry about emptying the water tank. The dehumidifier is well-made, and the handle and wheels are a big advantage. Therefore, if you want to change the position, just scroll it to the desired position. Would definitely recommend it to anyone who needs a good quality dehumidifier.

The dehumidifier was delivered on schedule. I move the dehumidifier around the house all day. Ideal for use at night. I noticed that the air is cleaner and no longer musty, which makes me feel more refreshed when I wake up. I did notice noise sometimes, it works in my basement at night, so noise is not a problem for me. Besides, you need to make sure that the dehumidifier is on a level surface. I am very satisfied with this product!
This dehumidifier is a first-class essential equipment.

I have been running for four months. Love this product. It has a stylish appearance and can be easily moved to another location as needed. I have been using it in the basement. Because my basement is so humid, the furniture and other items I placed have become moldy, so this dehumidifier is my life-saving straw. I used the included hose to connect it to the drain, so I never need to empty it. Definitely good value for money. I will buy the product again.
Amazingly efficient dehumidifier
By 'Fearne Parkinson ', Reviewed on 2021-02-01 11:46:38
I have been running the device continuously since it arrived 1 month ago, and it works normally. The automatic drainage function allows the water collected by the device to be directly discharged into my sump. The equipment is very easy to operate. When necessary, the rotating wheel is very good and can be moved at will. I originally bought it on the advice of a plumber, who told me that using a dehumidifier can eliminate the musty smell in my home. In general, I am very satisfied with the purchase.
Great product!

My mother has a moisture problem in her basement. The concrete and blocks are very wet. I have tried all other methods (not solved the problem), so I want to try a dehumidifier. I installed this device a few days ago and the reading told me the humidity was 88%. I set the required humidity level and kept it running. When I checked in the basement a few days later, the humidity level was 47%. It is indeed doing its job. I have installed an automatic drain hose, so I don't have to empty the water tank every day! I like it so far!
Great unit in a damp basement.

This is a great product. Can't believe the amount of water it removes from the basement I finished. Not sure where the water comes from, but the equipment continuously extracts water. Easy to use and move well. It effectively removes moisture from the air without producing annoying noise, and its hum is actually soothing. So far, I am very satisfied with this product.
Quickly remove water from the air
By 'Alexie Mccray ', Reviewed on 2021-01-11 11:10:57
Very satisfied with this purchase. I tried a larger size for the first time, and it removes a lot of water on humid days almost every day. Imagine what it would be like without a chance to dehumidify! The dehumidifier is still very quiet overall. What a great machine, there are already several buckets of water in the basement. I am happy to report that it also has wheels and can be moved easily.
