We live in a house built in 1940. The walls are rock, and 13" thick, so no moisture barrier or insulation. Same goes for the slab; nothing to stop moisture coming through. The house has always smelled musty. My wife is allergic to mold, so I needed to reduce the moisture inside the house in order to make it an unfavorable environment for mold growth. When I got the unit, it was plug and play: Just route the drainage hose to the outside, plug into power, turn it on, and let it get to work. Even without ducting, the humidity level in the most distant room reduced to 55% (with the humidity level set at 45%). Over the past few weeks, I have been ducting it into my HVAC, which could never bring the humidity below 80% (we live in Florida, near Gainesville). I first plumbed the exhaust (dry air) into the return at the base of the air handler. That move brought the humidity in the most distant room to 50%. Next, I bought 75 feet of Cat 8 cable, and installed the remote control near my HVAC thermostat. That worked perfectly. Finally, I cut an opening to my HVAC return 8 feet above where I connected the output duct, and ran flexible 10" ducting (Rubber-Cal HVAC Ventilation-Flex) to the intake on the dehumidifier. I now have even humidity throughout the house. With the remote set at 45%, the RH runs between 42% and 47% in every room. The unit itself is quiet, especially with the ducting connected. I can not wait for summer, when the humidity is so high, you need gills to breathe. *The remote control is convenient. I mounted it at 60" above the floor, which is the same level as the HVAC thermostat. The screen is readable from eye level, below eye level, and from either side. It is unreadable from above. I am 6ft, and I have to read it from an angle, or stoop to see straight on. If you buy the remote, consider mounting it so the tallest user can see it at eye level. BTW, the CAT 8 is backwards compatible with CAT 5a (supplied), and the 75 foot cable works fine. *There are scant instructions on hooking up ductwork. The instructions say to limit the total length of ductwork to 10 feet, but no explanation for this limitation. The instructions offer no recommendations for plumbing the unit in to the HVAC. Aprilaire has diagrams and instructions. Researching various other sites I found enough technical instruction to plumb the unit in to my HVAC. *There are auxiliary electrical connections on the cabinet, but the manual does not say anything about them, other than to illustrate their presence. *The controls give you the option of running the unit continuously. I am guessing this means the fan will run continuously, and the dehumidification function will cycle on as needed. I am pleased with the dehumidifier. Our home is so much more comfortable! The user manual could stand some improvement. The first photo is the installation into my HVAC system. The next photo is the remote viewed at eye level (with me crouching to view). The next photo is the screen when it is below eye level.

We recently purchased a home that had a long-standing issue with moisture in the crawlspace. Mold was found on the joists, etc. After remediation, I purchased this unit and the remote sensor to control the humidity. It has done a fabulous job! Very happy with the results and performance. Has kept the humidity to a constant and reliable level. Would highly recommend the product. Built like a tank!

This dehumidifier is a perfect dehumidifier for our basement, and it is powerful enough to be able to maintain the humidity levels in the house below 50%. This dehumidifier really takes the water out of the air, it has a capacity of 120 pints per day (PPD) of moisture. I have had other smaller and cheaper dehumidifiers but they are toys compared to this one. The modes cover every situation that I may need.
Works amazing!
By 'Dinah', Reviewed on October 12, 2021
This thing works amazingly well. I'll admit that it took me a few minutes to figure out the instructions, but it was impressive once it was running. The room is used for hydroponic gardening and has multiple hydroponic units in it constantly running water. The humidity was over 75% when I started to run this unit, with less than 50% as the goal. It took a week, but the unit removed over 100 gallons of water from the air and reduced the humidity to 45%.

This is a powerful machine, and if you have a big basement like mine, this is the unit to get. It is straightforward to install and hook up. Simple to use, and all the instructions and filters are easy to understand and change. All you have to do is plug it in and select the settings you need. The humidity in our rental went from 98% to 56% within the first day and down to 43% by the second morning.
Excellent !

We ordered this ALORAIR dehumidifier based on our positive experiences with other products from this company. The air purifier worked great, so we decided to give the dehumidifier a try. I have to say. I'm impressed again. We have a large commercial office over 100 years old, and our basement gets very damp, especially with the heavy rains we've been having. This one unit keeps our entire basement dry. The built-in filtration is a huge plus. You really can smell the difference. If you're looking for a well-built, reliable unit, this is the one for you!
By 'Mae Evans', Reviewed on August 05, 2021
We had a big basement, so we used a door handle to divide it into two parts. The first night after we set up the dehumidifier, we closed the door and let it run to see how it worked. By the next morning, when we opened the door, and we noticed that a huge difference in humidity between the two areas. The basement was dry on one side and wet on the other. Also, instead of using buckets to catch the water, the dehumidifier uses hoses to put it into the basement drain. We don't need to pour water at all. It's very convenient and effective.
Great dehumidifier!

The machine saved my poor memory! Forgetting to turn off the electrical appliances is an additional expense to our family. The function of Memory Starting And Turn On/Off Automatically is customized for us. This product removes the moisture while helping us to save energy expenses. Thumbs up!


Can it for grow room?

It should work as long as the moisture removal capacity of the unit is high enough to handle that of the peak grow room moisture load. This would be important if you have a maximum humidity level that you want to maintain. An estimate of the room moisture load would allow confirmation that the selected unit is adequate for your application.
