I like it, it works well
By 'Mckenzie Partridge', Reviewed on 2020-11-16 10:57:47
It can actually maintain 50% humidity in the basement, even without running all the time. I hope it will last for more than five years, which is different from all the other products I have bought, but so far, I like it and it works well. Learn the lesson of money again-if you buy it cheaply, you will eventually throw it away. Be sure to buy quality things.
This machine does the job
By 'Buster Gallegos', Reviewed on 2020-11-09 11:55:28
I live in South Florida and I have a 2000 square foot apartment with air conditioning, where I often experience high humidity problems. Therefore, I decided to try this dehumidifier. I placed the dehumidifier in the basement, where the humidity is highest, and set the humidity level to 40%. It reduces the humidity very well. The quality level of the dehumidifier seems to be high. I am very satisfied with this machine. My only question is how long it will last.
Great product
By 'Aniya Garrison', Reviewed on 2020-11-02 11:21:30
I am very satisfied with this dehumidifier. Our house was very old and moldy before we bought it. It is located in the main living area of the house and is relatively quiet, although I am not sure if it is quiet enough to accommodate the bedroom. After using it for a week, I noticed a significant difference in the humidity in the house. The morning is most noticeable because usually the temperature is not high and the air conditioner cannot be activated at night, but it used to be very humid and uncomfortable in the morning, but this has solved this problem!
By 'Roy Joseph', Reviewed on 2020-10-26 11:22:30
The dehumidifier has been running for several weeks and we are very satisfied with it! It is not very loud, nor is it very loud, so it is not inconvenient to run 24/7. Since we have been using dehumidifiers, the humidity in the basement is always within an acceptable range, and it feels comfortable to enter the basement again. In general, we would definitely recommend this dehumidifier!
Great workhorse dehumidification product
By 'Pascal Ireland', Reviewed on 2020-10-23 15:33:42
I bought this dehumidifier and used it in a medium-sized basement for 3 months. It is compact in size and can affect the entire room from the corner. It can be easily moved if needed. Run 24/7 and eliminate dampness and improve the smell of the basement. It still looks brand new after 3 months. The drain/hose can draw out all the water well. In general, it is recommended as an ideal dehumidifier for drainage equipment.
Great dehumidifier!

We have a fully finished basement. We bought this product to solve the humidity problem, and the effect is very good. In fact, it works very well. The basement is usually our entertainment place. After sweating, if the space is humid, the sweat is difficult to evaporate, so a dry environment will be more comfortable. Buy without hesitation, I think it's worth every penny!
First-class dehumidifier

After purchasing several dehumidifiers of different brands, we finally got a truly effective dehumidifier, this AlorAir®Sentinel HDi100 dehumidifier. It keeps the humidity in the basement stable. It can start and stop without failure and can drain normally. We drained directly into a sump, and there was no water in the tank. It keeps the basement under our 2,300 square foot house always dry and comfortable.
Good appearance and good function

I decided to buy a dehumidifier for the basement because the shoes and clothes stored in the basement were moldy. The musty smell is unbearable. The dehumidifier is here, it saves my basement. It is packed and shipped on time. The appearance of the unit is very good. It is very easy to use, and all in all, it works well. The moldy smell disappeared, and the items were not moldy or rotted. The price is worth it.
Easy to use, get the job done!

I bought this dehumidifier for the basement which is wet all year round. It really absorbs a lot of water. After a few days of use, we opened it for several hours a day to reduce the humidity in the basement to a comfortable level. It is large enough to accommodate the basement. It is very fast and effective. The design on the control panel is very good and it is very convenient to use. Cleaning the filter is very easy. Very good product and love it.
