  • Great So Far
Color: white
I bought the AlorAir HD 90 in October, 2021, to replace a 10 yr old Santa Fe unit that died for my sealed 1500 sq ft crawlspace. I did a lot of research before buying this so hopefully it will pay off. In no particular order, here are some of my initial observations after running it for 6 weeks: 1. It appears to be made of good quality materials and it is definitely not underpowered for my purposes. I like the digital controls which my old unit lacked. 2. There is no drain tube included so I reused the flexible plastic line I already had, just make sure to loop the line over itself per the instructions (helps ensure proper discharge of water from the unit). 3. It was really easy to install, just set it in place, level it (a wrench does the trick), connect the power and drain lines, turn it on and set the humidity level. Took about a day to drop my humidity level from 80% to about 55% - just above what I had it set at. I did set the unit on some scrap 2x4 wood pieces to elevate it so it would adequately drain to the sump pit. Don't expect any unit to push water uphill to a drain or sump pit. 4. It is very quiet. I have it sitting under the living room and I never hear it running. It seems to be pulling about the same or slightly less power than my dead Santa Fe unit. 5. The exhaust fan on the unit is pretty powerful. I initially thought that I might duct the exhaust air away from the unit to increase circulation in my crawlspace which is only about 3 feet tall but the unit seems to have no problems keeping the whole area within tolerances. 6. I have a separate remote temp and humidity sensor set up about 15 feet away from the AlorAir unit. I recommend having one so you can monitor your crawlspace and verify that the unit is working properly. The unit seems to keep the humidity with a few degrees from what I set it at so I am pleased with that. The AlorAir unit says it will keep it within 5% humidity from what you set it at. 7. Lots of people seem to complain about the unit dying early in the one star reviews. While mine is new and working fine I will note that even if you were to buy this unit from a professional installer or specialist, they often do not service the units beyond basic diagnostics. So, when these spendy dehumidifiers quit working, you can often be left on your own unless regardless of the model purchased or who you purchased it from. I hope my unit lasts at least 5 years but time will tell. 8. Amazon advertises extended warranty protection for additional fee on this unit for up to 4 years which seems pretty good until you start reading the fine print. From my research, it doesn't seem like this unit qualifies as “houseware” and some customers who buy the Amazon warranties say that Amazon will offer these warranties on products that do not qualify. If your product doesn't qualify for protection then it seems like a crapshoot as if you can even get a refund on your warranty purchase. I skipped the extended Amazon warranty. 9. I bought this unit in part because unlike AprilAire and Santa Fe, you can install this yourself without voiding the warranty. Those other two units require a pro install. It is an expensive unit but I wanted something more commercial grade and hopefully long lasting since no one likes messing around in their crawlspace more than they have to. ... show more

  • Unit has a nice warranty, but does not last. Look elsewhere!
Color: white
I bought this unit slightly over 1 year ago. It quit working after 2-3 months and after documenting the problem, Alorair sent me a replacement. It seemed to work fine until April of this year. It runs but is not dehumidifying. Filters are clean. Remote runs just fine. It just does not lower the humidity in my crawl space below 57%. When it was new, it would run the humidity down to 45%. It seems to run almost constantly and never reaches the 47% target level that I set. I am going to look at another brand before summer gets here. Disappointed twice! I am not going to give them a chance for three strikes. ... show more

  • Deceptive warranty - Do not waste your money
Color: white
Alorair's web site describes their 5 year warranty like this: "5 YEARS WARRANTY- We believe in quality and after-sales-service, All our high-quality ALORAIR basement/crawl space dehumidifier is made for your full utilization. It is sure to last long and still keep its shape look. Your 100% satisfaction is guaranteed with a 5 Years Warranty and a great after-sales-service team countrywide." My wife and I never imagined spending $1,000+ for a dehumidifier. But with a statement from a US company that: "Your 100% satisfaction is guaranteed with a 5 Years Warranty and a great after-sales-service team countrywide," we bought with confidence that the HD 90 was the right investment to make. Only a US company with confidence in their product would offer a 5 year warranty and 100% satisfaction guaranty. If it were to have an issue, there was an "after-sales-service team" nearby to perform warranty repairs. So, we purchased the HD 90 from Amazon for more than $1,000. At first, the unit worked great. It reduced and controlled the humidity in our basement and we were very happy. Then, after less than 2 years (not even half way through the warranty), the HD90 stopped dehumidifying. Although the unit would cycle on and sounded like normal, it was't removing moisture from the basement air. Knowing we had the 5 year warranty, I contacted Alorair's customer service team about warranty service. They happily shipped me some parts (new capacitor and circuit board) to replace on the unit. Unfortunately, the replacement parts didn't fix the issue. Still, no dehumidification. As it turns out, the warranty really isn't for 5 years, their "service team" is not "countrywide," and there's no 100% satisfaction guaranty. I was told by Alorair's service team that, since our unit didn't fail during the first 12 months, Alorair won't repair it under the warranty unless we pay to have the unit shipped to them, and then pay to ship it back to my house after the repair is complete. We live in Maine, and their only service facility is in California. The unit weighs about 80 pounds, so the cost of round-trip shipping cross-country (6,000+ miles) is wildly expensive. In the interest of full disclosure, Alorair did give us an alternative to paying to ship the HD90 the 6,000 mile round-trip for repairs: we could buy a different model unit from them for a few hundred dollars, and it would have the remaining warranty period carried by our defective HD90. So, instead of paying $1,050 for a dehumidifier guaranteed to last at least five years, we'd really be paying closer to $1,400. The problem is that we don't want to spend $300 more for a different/second dehumidifier model. We already paid plenty for what is supposed to be a high-quality humidifier backed by a five year warranty. Needless to say, Alorair's warranty really is not for 5 years. There is no 100% satisfaction guarantee. Nor is there a service team in your vicinity unless you live in Southern California. Given that our unit lasted about 2 years, we figure that we paid a little over $500 per year for Alorair's HD 90. Had we known they would not honor the warranty, we wouldn't have spent that much on the Alorair unit. Unless you live in or near Ontario, California or don't mind buying a second dehumidifier after your HD 90 stops working mid-way through the warranty period, you may want to consider looking elsewhere and exploring other brands of dehumidifier that are less costly and a better value. ... show more
