High-quality products, well worth the price!

This is a great dehumidifier. Can't believe the amount of water it removed from the basement I finished. Not sure where the water comes from, but the equipment keeps extracting water. Easy to use and move well. I can't say how long it will last or how durable it will be, but it looks very compact, looks good, and seems to be a great value product.
Definitely worth the price

This is the best dehumidifier I have ever bought!!! Easy to move, operate, and empty. I have been using it for about 2 months and it does make the basement no longer damp. The air is good and there is no moisture. Buy it... you won't regret it!
Wow. Really efficient

When my original equipment broke down, I purchased this equipment to use in my basement. It thoroughly cleaned the air (no more basement smell) and sucked all the moisture into the water tank. It's really fast, I don't have to empty the water tank every day. I use a hose to drain water. If you want the dehumidifier to always operate at home, I totally recommend this unit.
This machine is awesome! ! !

We got this because our apartment was too damp, the carpet always felt so wet, the salt (in a jar) was ruined, and after we found mold on the floor, we bought this after some quick research product. This thing is amazing! The humidity in our apartment was reduced to a normal level and there was no mildew. It is very easy to set up and comes with a manual. All in all, I like it, it does a great job and we are very satisfied!
good quality. Excellent performance for several months.

I usually use the product for a while, and then write a review to ensure that the product is of good quality and will not be damaged within 30 days. Before purchasing an AlorAir Basement/Crawl Space dehumidifier, I tried to do as much research as possible to determine which brand seemed to have the best reputation in terms of quality, price, and warranty. After 4 months of use, it has exceeded my expectations in all aspects. I have nothing to say about this unit, I highly recommend it.

Bought this for my basement. The basement is sometimes very humid for many reasons, I believe every homeowner has experienced it. The working principle of the dehumidifier is very simple. It has a hygrometer on it and can regulate itself well. I have a separate thermometer/hygrometer combination, which I moved to the basement for comparison and read very carefully. After spending a day or two in the basement, I noticed a huge difference. There is no moldy smell/humidity. highly recommended. After two months of use, it has no quality problems.
Help improve basement air

Sentinel HDi90 works well. When I don't use it, the humidity in the basement exceeds 60%, so it has a musty smell. It can keep the basement at around 40-45%, and it definitely helps eliminate odors. My basement is large, so there is no smell in the area, but the further area is still stagnant. I might buy another one on the other side of the basement in the future.
Worth investing

This Duct-able Version Sentinel HDi90 dehumidifier is a great choice for me. I installed one in the garage to control moisture and water leakage, and by adding a duct, the space was completely dry and hygienic. My garage is now a good place to store and work.

I live in a small apartment in Florida. The humidity is very high. Sweating in the summer makes it uncomfortable. Although I can turn on the air conditioner to cool down, it does not dehumidify well. My last model no longer works, so I got a 90 pint Sentinel HDi90 unit. This unit has perfect functions and good performance. It pumps a lot of water from the air in just one day. Love this product!
