Work great in a short period of time. I would recommend this dehumidifier to anyone looking to buy it.
Favorable dehumidification performance !
By 'Harri Haynes', Reviewed on January 16, 2023
After trying almost a dozen different dehumidifiers, I decide to try this unit. So far, I've replaced three standalone units with this one and I'm very satisfied. It's so noisy, but it eliminates significantly more moisture from the air than typical standalone units. Since this unit doesn't include a tank, you either have to drain it or use a condensate pump. I hope they'd add a remote flooding contact.
Satisfied with it!

Having moved to a new home lakeside, the humidity levels in the house were noticeably different from my prior home. The humidity caused the real issue was the increase of bugs in my basement, particularly centipedes. I decided to get a dehumidifier for my basement. It took about four days for the humidity in the basement to permanently adjust from above 80 percent to a consistent 30 percent, and the change was very noticeable. The amount of bugs has dropped off by nearly two-thirds, and alongside the dramatic reduction of insect life, the air quality is considerably better. I can take a deep breath without feeling as if I'm breathing through a rag. On top of that, maneuvering the large device to be in a position for complete drainage was surprisingly easy, much easier than one might expect for moving such a substantial product.
Highly recommend it!
By 'Leila', Reviewed on October 07, 2021
I figured this machine would be precious during our humid summers. What has surprised me is how much excess moisture is in my home. Our basement has had moisture for so many years, and the recent heavy rain made it worse. We brought this dehumidifier to help it out while we were working to fix this problem. Based on its ability to draw down the humidity to ~50% from close to ~80%, I highly recommend the unit.
A well-built commercial quality unit!
By 'Isabella Rose', Reviewed on September 29, 2021
My crawl space is approx. 2400 sq feet, and it had some humidity problems. So I sealed the crawl space and installing AlorAir HDi100. Within a few days, the crawl space humidity dropped from 60 to 50. The HDi100 was a straightforward setup. Easy install-you need an AC receptacle, some cement pavers to use as a base, and you need to provide an exit for the pump. It has worked flawlessly. Condensate pumps are a real benefit and can keep you from emptying the reservoir. It also has a changeable air filter to protect the evaporator and condenser coils. The controls are simple to use. I elected to use an indoor controller and placed it near my thermostat to monitor and change the humidity level without accessing the crawlspace. I liked the fact it was a well-built commercial quality unit and had a 5-year warranty.
Glad to have this unit!

My exterminator warned me earlier this year that I need to find a way to reduce my crawl space humidity. The floor insulation in my five-year-old house is starting to look like cotton candy, and my ductwork is dripping. I live in Eastern North Carolina, so there is no time of year that is humidity-free. He recommended that I seal my crawl space vents. After closing 20 foundation vents, I bought this dehumidifier after I did a fair amount of research. The installation was very straightforward. As soon as I turned it on, it got to work. I installed the unit on August 17th, and the relative humidity of the crawlspace air was around 88%. Within two days, the unit reached the set-point of 55%. I have since lowered the set-point to 50% RH, and it maintains this with ease. I have not once heard the unit from inside the house, which is a huge plus. Time will tell how the unit holds up, but it seems to be built like a beast. Even though I'd instead have spent the money on something sexier like a new TV, I am glad!
Extremely pleased!
By 'Noah Rodriguez', Reviewed on August 20, 2021
I have a roughly 550sqft basement woodshop that's open to the rest of the basement, so overall, around 800sqft of space. And I need my shop at the proper humidity. Wood and machinery dislike high moisture. My frigidaire was having trouble bringing the humidity down from 61% in this stormy season. Put this guy in, and it brought it down by 12% in about an hour or so. Another hour or two, and it got down to 48%, and I have it set to 45%. It's also quieter than the frigidaire, pretty impressive. Extremely pleased!
Great dehumidifier!

Easy operation

I don't have any talent for electronic products, but I can frequently operate this machine. It means everyone can use it, which just approved the promotion introduction " Easy Touch Button Control Panel and Simple to set up" makes you look like an expert. PS: Damp removing performance of the dehumidifier is perfect, and I am satisfied with it.
Drain directing is great!
By 'Mason Adams', Reviewed on May 22, 2021
This dehumidifier is working hard in my damp basement right now. Most of our basement is finished, but with a hundred+ year home, we end up having patches of the drywall someone added down there get mold all over it, I assume because sweating pipes and moisture in the walls. Not exactly sure. Just know that having a dehumidifier running all summer has been our solution for now. Having the option to have a hose hooked up and have it drain directly out of the house is great! It makes it so I am not having to dump buckets of water out every few days.


What's the diameter of the soft discharge water tube? in case I have to run a discharge pvc line and connect it.

I'm not sure. I think the spec sheet gives the inside diameter of the discharge tube. I used a brass nipple and ran the condensate tube into the PVC sewer pipe.
How loud is it can I put it inside a furniture store?

It is louder than I expected, but I have become accustomed to it since it is my basement. It would be a distraction if in a publicc area.
