ALORAIR 180 PPD Commercial Dehumidifier with Pump, 6-Year Limited Warranty

I bought the ALORAIR Commercial Dehumidifier with Pump (180 PPD saturation / 85 PPD AHAM) for a damp crawlspace and unfinished basement that constantly fought humidity and musty smells. After running it for several weeks, I’m genuinely impressed. This unit pulls moisture like a champ. Within the first couple of days the humidity dropped dramatically and has stayed consistently low. The LGR technology really does make a difference in lower-humidity conditions compared to regular residential dehumidifiers I’ve tried before. The 210 CFM airflow moves a serious amount of air, and the built-in condensate pump with the long hose is a game-changer—set it and forget it, no more emptying buckets. It’s surprisingly compact for the power it delivers and fits easily in tight spaces. Noise is very reasonable for a commercial-grade machine (well under the “loud industrial” level I expected). The auto-defrost and memory restart features work flawlessly, and the solid build quality feels like it can handle real job-site abuse. The 6-year limited warranty gives excellent peace of mind, and from what I’ve read the company stands behind their products. Setup was simple, the MERV-8 filter is easy to access, and overall operation has been completely reliable.

I’m very happy with this dehumidifier. It works really well and does a great job of removing moisture from the air. It’s easy to use, runs smoothly, and I was actually surprised by how much water it collects. The size is convenient and it doesn’t take up too much space. Overall, it does exactly what I needed it to do and has been reliable so far. Definitely a good purchase and I would recommend it.

PURCHASED May 2019 I purchased this unit based on most reviews, and I’m 100% pleased so far only had about 3 weeks. But since my 18 year old Kenmore unit that worked perfect died, I’ve had nothing but junk since everything today is china crap for $250 do your self a favor and spend the Money, you get what you pay for. This unit rocks! It’s super quiet and is commercial grade with out the super high price $1600-$2500 plus at $999 it’s perfect. You’ll go through 3 of the cheap ones that don’t even pull the humidity out. This unit is in a completely finished basement no visible water ever but can run 55-60 % humidity this unit has a pump with about a 25-30 foot hose it pumps very even no high pressure that would make the hose jump out of a sink where I have it draining I tested it over night in a 5 gallon bucket so in about 12 hrs it filled the bucket 1/2 full. It’s running my basement at 46% humidity at 69degrees When the basement goes down to 65 degrees or lower it does ice up the coils but it automatically goes into defrost for a few min and defrost the coil. The digital read out Is awesome it reads the temp and humidity going in and out of the unit also as you scroll through it reads the coil temp, the actual compressor amps at3.6, total amps with the squirrel cage style blower about 5 amps really efficient on electric. Reads the total job hours and can be reset this is the total time it’s been running. When it reaches the humidity set point the entire unit shuts down. It retains its settings if power fails. And it also ready total life hours. It reads grain PPm. And has a screen for total in and out temp and humidity. It has a metal washable slide in filter, and the hose can be curled up and it has a Velcro hanger, very nice power cord that lights up at the wall outlet. It has a button to surge the internal sump pump which count downs 25 sec as it manually drains the water if you press it otherwise it does it automatically when it’s full. And the warranty is better then many at much more cost . So these are the pros ! My only slight con is it is heavy about 70 lbs but it has two very strong handles to pick it up I had no problem. And other con is I have a burber carpet in my basement and when I slid the unit to the wall the rubber feet made black marks on my carpet but it cleaned up with soap and water. Nothing to make me not want to buy it. I will be purchasing another one for my 1200 foot shop. Also you can stack them and hand truck it. The plastic housing is super quality and tough stuff. This is a super quality pro unit. Oh btw my basement is also 1200 Sf. They say in the listing it can be submerged ? I’m not sure about this or why you would want to cause the power cord that plugs into the unit has a little flap that pops up to plug the female end in but it surely is not a water tight seal so I would not recommend this it will short out plus why would you it’s not a sump pump. It’s a dehumidifier? It has a small sump pump built in to pump out the water it collects but not to pump out lets say a foot or more water flooded in your basement. For that I would get a sealed pump, then once all your damage water is out you certainly can now use this to dry up the environment. Highly recommend I hope the review helps ! PLEASE READ !!!!!! UPDATE May 2021 unit failed after 15 months error code E5 refrigerant leak! Like many others that bought these units. Ok so here goes! I tried to email the company twice about my problem, they got back after the second email and saint to call. I called and spoke to Cynthia very nice but just like many others it was over a year old and they will not issue a shipping return label. I live on the east coast there in Cali.. they wanted me to pay $200 to have a new unit shipped out but continued on my existing warranty! Really??? I’m going to pay an additional $200 on top of the grand i already spent to try again? After telling her that many people are having this problem, she understood my frustration but still no resolve yet. Had to send pictures of the error code they wanted to send me out a new sensor. But I knew it was not a sensor cause the unit just ran and made no heat it was done. Then they wanted me to pay $400 to upgrade to a $1400 unit made with the same components. Btw this is not an American made appliance. It’s made in China. When I asked to speak to a supervisor I was told there all in China and could not speak to me because of the time difference??? Really ok how about at 3 am our time? There Amazon page is not true as an American company selling made in America products! Not true. After weeks of emails and phone calls they offered to ship another unit. I refused after all I was going through I wanted my money back a full refund. They finally refunded the full amount but I was expecting they were sending it to me directly, they issued a refund to a credit card I used 2 years ago on Amazon to a account I closed and no longer have access to. But has a balance so I can’t get the money back and no longer use that company, so I’m screwed. I have a 90 lb big yellow door stop. And no money to buy another unit. I should have excepted the new unit at least I would have had something in hand to maybe work for another year or so. So now I have to repair this unit myself which I will because I know how to fix refrigeration systems. But I shouldn’t have to do this. So please please heed this warning! This company does not have any service ability they are an American front for a Chinese product and all they can do is issue parts, help you take it apart and try and fix minor things. But if it’s a major thing like a leak or a compressor failure your screwed. And let me tell you I’ve been researching these for years. So when you see a ton of these that all look similar, but from different companies. There all the same. All these things are being made in China hundreds of thousands and being sold to any company in the USA and have their name put on it. Another company colzlar same thing. They will only replace it if your lucky. I specifically went with this unit because it listed it used a rare earth metal in the coils with a spec coating to prevent refrigerant leaks which is very common on these things, cause there junk! We have refrigerators in our homes that last 10,15,20 years and never have a problem. But they can’t make these crap dehumidifiers last 2 years. And anyone who’s not familiar it’s a simple refrigeration system like your home frig. Just operating at a different temperature. Or more like your home A/C it removes the humidity. In this case instead of the warm air blowing off the condenser outside it blows it back into the room and heats the room up, or some you can duct outside. Unfortunately this is the reality. Don’t get me wrong you see my first review was great I was loving this over the $200 household units. It kicked butt! But they don’t hold up. Oh and do you know what the rare earth metal is ? Aluminum! Lol! That’s rare huh! With an epoxy coating to help preserve it but it still leaked! If they just used good copper coils and braised them it would last 25 plus years. But that’s our life today it’s all throw away crap! I bet these cost less then $150 to make in China and they sell them here for a grand or more.! Now I’ll have to epoxy the aluminum coils under a vacuum to repair it then put in the 21 oz of refrigerant. They have no service centers anywhere in the country. I told them why don’t you reach out to local refrigeration and A/C companies to do your warranty service, and I was told that most companies don’t want to work on them . Hmm maybe I should take this on, unless it’s because they don’t want to pay? Its cheaper to send you another piece of junk since it doesn’t cost anything to make in China. If you decide to buy any of these things from any of the different companies selling these on Amazon I would highly recommend purchasing the Amazon extended 4 year warranty it will be well worth it! At least you’ll either get a new unit or a refund through Amazon! Good luck everyone! Such a scam of crap! It doesn’t take much to make something decent that will last! They just don’t want to! quality is just out the window.!

Update Edit 8/11/2026 5 Star After successfully contacting Alorair they sent me the needed part to get my dehumidifier running again. When this unit is running it sure drys things out.Thank you Edit 6/23/26 1 star unfortunately the unit quit working, and unable to get support. Sadly disappointed. It doesn't matter to have nice website, videos & good product without support. I now have a non working unit & have turned to another brand to get me back online dehumidifying. Dehumidifying is not something to be offline for extended period. We use this product to keep our basement dry and control humidity in our house. It works very well with minimal maintenance. However, a recent breakdown caused some stress about after-sale support. Fortunately, ALORAIR provided troubleshooting help and sent a replacement part under warranty. Relief!

I purchased the ALORAIR Dehumidifier in September 2025. Let’s be honest, this is a commercial grade dehumidifier. It moves a lot of air, it pulls in a lot of moisture, and it’s built for large spaces. If that’s what you need, it delivers. It’s plug and go as advertised and it’s powerful. It’s *not* is a whisper machine and it’s not marketed as one. It pushes serious airflow and has high moisture removal rates. That said, the noise level is tolerable for the performance you’re getting. I ran into an error code5 about five months after purchasing the unit. This is where I want to give ALORAIR customer services some credit. Their support team walked me through a very methodical troubleshooting process, which I appreciated. I followed up with them by sending clear photos, step‑by‑step notes, and replicating their tests exactly. Based on that, they were able to identify a faulty temperature sensor on the coil and sent me a replacement thermistor. I installed it as instructed with ease, the error cleared immediately, and the unit has been running perfectly ever since. I also gained a better understanding of the unit through this process. Bottom line: - This is a large powerful machine. It works well. - Anything can have faults, it’s how you address and learn from those faults. - The fault I had, ALORAIR address and resolved systematically and swiftly.

This humidifier works really well. It has kept my basement offices dry as a bone. It has one design flaw. As it has an internal drainage pump, if the pump needs work it's a big deal to disassemble the thing and get to the pump. At 21 months of service, I started getting an error message that indicated the pump was not draining properly. I looked up the troubleshooting and saw how to open the case and get to the pump to clean it. A filter in the system had become clogged white slimy gelatinous stuff created by some organism living in the water. I cleaned everything but the pump wouldn't work when I reassembled it. Support was very good and they are sending me a new pump. In the meantime in the most humid time of the year, I'm out of function for a week. I paid a little bit more attention to the cleaning and maintenance directions which advises you clean the pump to three times a year. This is the problem with an internal pump. There are algae suppressing tablets you can put in the water reservoir but you still have to take the case apart to get in there and drop a pill in. It was a lot less expensive than my previous Santa Fe dehumidifier which had an external pump. So I'm saying it's a great humidifier that really well but you need to do maintenance They could've designed it better. 10/1/27 14 months since I switched the pump on this dehumidifier. Support was very good sending me the parts and walking me through how to change it. Since then I haven't done any maintenance but now I'm starting to get the E4 error message which means the pump's not working. If I unplug it and plug it back in the pump goes back to work. I'm about to contact support to see what I do about this.

I recently started using this dehumidifier, and it’s been a lifesaver for keeping large spaces under control. The performance is no joke—it pulls a huge amount of moisture out of the air quickly, and the airflow is strong enough to keep an entire basement or warehouse feeling drier within hours. I’ve used smaller units before, and the difference in efficiency here is night and day.

Purchased this unit to help dehumidify a finished space in my garage. The unit worked perfectly and efficiently dehumidifying the space. Then one day about 6 weeks into ownership it wasn’t running and was displaying an e5 code on the display. I unplugged the unit and plugged it back in and it ran for another day or two and then threw the same error code and stopped working. Now it won’t run for longer than an hour. I contacted the company and they requested a bunch of pictures and information. Sent them in an email and they never responded. So I called again they never “received” my email. They then provided me with a phone number to text my photos. So I did. Then they responded a few days later asking me for an image I had already sent them twice. So I sent it again. Waited a few more days no response. I called back and spoke with them and was told the agent assigned to my case was not available but they could see that there was an update to my ticket and that they would need me to ship the unit back. This unit is 2 months old and it isn’t functioning. I do not have the original packing materials and having to source packing materials and pay out of pocket for them to remedy this situation is ridiculous. I was told they would need this unit back before they ship a new one. This company and their products are a joke. As soon as they found out a unit that’s less than 2 months old is not working they should have shipped me a box with a return label and as soon as it was dropped off shipped me a replacement. Now I’ve lost the money I spent on this turd and had to buy something else to replace it because I can’t afford to not have dehumidification. Lesson learned. Buy an aprilaire from a local supply house who will back their products. Don’t buy random junk off amazon.
