I’ve got a sealed crawlspace under my home that needs dehumidification. I bought this unit because it is short (not a lot of height in the crawlspace) and had a ducted option, which helps me circulate dry air around several large obstructions in the space.
The unit was double boxed (dehumidifier w/ 4 foam corner brackets in a box, then that box was padded and inside another box). There was a hole punched in the outer box during shipping, but the inner box was still intact and undamaged. The unit itself was in perfect condition and started right up.
The funnel piece where you attach the ducting (not required) was interesting. I expected that the ducting would go OVER the plastic funnel and would be secured using a band clamp. Instead, you have to use expandable ducting with a wire spiral in it and the ducting then screws INSIDE of the funnel piece. It attached nicely (luckily I had the right kind of ducting) and it worked well. Here’s the duct kit that I bought, which I would order again: https://www.amazon.com/gp/product/B07WNK7N7F/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1
The unit felt very industrial and was well made. I opened it up and took a quick look around… components were well made and electrical connections were solid. The filter is easy to remove and reinstall after cleaning. The controls were intuitive. I also bought the additional remote control (on a 25″ wire, provided with the unit) and was happy with that (allows me to check on the humidity level and change settings without crawling on my belly to get under the house).
It makes a bit of noise (It’s got a fan moving a lot of air, so that’s to be expected), but it was quieter than I had anticipated and I was happy with the sound (I can’t hear it in the house, even when standing 2-3 feet above the unit (it being in the crawlspace right under the floor I was standing on).

In spite of some problems that I initially encountered, I believe that for its operating capacity the Alorair H55 (Blue) Sentinel dehumidifier is one of the best products on the market place today.
Why do I think this dehumidifier is so good? To be honest my past experience with the entire dehumidifier manufacturing industry has not been a happy one. In the past 10 years I have bought (and obtained through warranty exchanges) over 8 dehumidifiers. I have a relatively small encapsulated crawl space (1,400 SF) which I kept dehumidified using residential 35 Liter per day units. The units that I bought were manufactured by Frigidaire, Friedrich, and Hense. They are all junk! They are designed to fail within 12 to 24 months. Although one would think with the vast choice with the plethora of various manufactures of residential dehumidifiers that quality would vary; having removed the cover off of these failed units it appears that the functioning components (compressor, condensing, and evaporating coils) are all the same and probably come from the same factory located somewhere in China. Why do they fail within such a short period? Bad design. (1) The evaporator coils operate under high pressure 410 Freon, with thin walled copper tubing (environmental and energy efficiency improvements), packed with aluminum cooling fins for condensing room humidity, all held together with carbon steel plates on the ends of the coil unit. The high pressure Freon environment within the thin copper tubing fails within 24 months due to formicary corrosion caused by the dissimilar metals (aluminum, copper, and carbon steel) in contact in a damp environment setting up a corrosion voltage differential on the evaporator coil. (2) Placement of the humidity sensor directly in contact with the evaporating coil in the upper corner, insures multiple and repeated false starts for the dehumidifier compressor. When the unit shuts down after reaching proper humidity levels, the evaporator coil is still wet, and as it drys out the humidity released will send a false signal that the room humidity is too high and thus trigger the unit to start up. Worse when moisture evaporates, the resulting water vapor is lighter than air and rises and triggers the sensor. Excessive cycling on and off results. Lastly it is impossible to repair the units when they fail. They are intended to be disposal products. When I hauled them off the the landfill (as hazardous waste) it was shocking how many failed dehumidifiers were stacked together at the landfill.
I finally decided to quit buying junk and started researching crawl space dehumidifiers. Most crawl space dehumidifiers are overpowering for my needs (100 ~ 200 pints per day). The Alorair HD55 is one of the smallest crawl space dehumidifiers on the market. And it is a quality design. This unit has a coated coil (in which the aluminum fins and copper tubing are coated) and is held together with stainless steel plates all of which protects against premature evaporator coil failure due to formicary corrosion. Secondly the humidifier sensor is separated from the evaporator coil and is located on the lower end of the unit to minimize triggering by evaporating moisture from the evaporator coil. Additionally a remote controlling sensor is available as an option with a 25 foot cable to enable full separation from the senor from the evaporator coil. The unit has a MERV 8 removable filter to keep the coils clean. It is very quiet when operating. The only way for me to tell if the unit in the crawl space is running, I have to put my ear against the floor to hear it as the sound is too faint. Additionally, I highly recommend the hanging unit when installing. The rope system minimizes the conduction of vibration, and it raises the unit to get more height when running the gravity drain pipe. Additionally operating the unit directly below the floor joists is more efficient as humidity rises and can be more effectively removed during operation, than if the unit is located on the crawlspace or basement floor. Another plus is that while the humidity sensor operates to the nearest 5%, the actual humidity setting can be set within 1% intervals. I have a separate hygrometer sensor in the crawlspace which measures humidity within 1% intervals. This unit is able to keep a steady humidity level of 41% with a variation of only 1 % +/- when using the remote controller and keeps a steady 40% with no variation when using the sensor on the unit. None of the other junk units that I used to own could keep a steady humidity level, as they operated with variations of +/- 5% at a 45% setting.
Yes I did have some problems as the first unit delivered failed almost immediately It is not clear whether the unit was defective or whether it was damaged in shipment. I suspect that damage in shipment is a common problem. The support staff was very responsive and arranged to get a replacement unit shipped to me in two days. I was also given a return label for me to ship the defective unit back at no cost. Replacement unit is running great. I would highly recommend that you save the shipping box for any future returns. In spite of this I still recommend this unit.

I use this to keep the moisture down in my rv. I live in the pacific northwest and during the non winter seasons it can get humid. It rains a lot here. Before I deployed this unit my rv would get moldy inside in a matter of a few weeks. One time I found an inch of white mold on my steering wheel. Yuk! After spending a lot of effort (and a lot of white vinegar) getting rid of the mold I bought this and there has been no problem since. It’s much better than a house unit because it can discharge water out a hose to the outside. Compared to what this is made for, my application is light duty. After 3 years the humidity no longer matched my humidity gauge. It was off by 15%. Customer service helped me trouble shoot the problem, which turned out to be the humidity sensor. They sent me a new one free, but it turned out to be incompatible as it was a newer design and it gave an error code of E1. When I reported that, they scrounged an old design sensor and sent me that, as well as a new main board to match the new sensor. Free. Although the manual doesn’t contain the error codes or much in the way of trouble shooting, they have quite a library of utube videos for reference. Combine those with TOP NOTCH customer service and I would not hesitate to buy this unit again. Replacing modules and filters is very easy requiring only a screwdriver and needle nose pliers. I highly recommend.
