Love it. It is a bit loud, but it is just the noise of the air flowing. I let it run for 32 straight hours the fist time I plugged it in.? First photo was after about 24 hours, then 28, then 32 hours. The last 8 or so I was actively working in the area around the fan. Photos tell the story of how well it cleans the air, in my opinion.

Powerful and cleans the air fast. It was packaged well and easy to install. It is exactly what I hoped for and does the job as promised. It is not quiet, but not as loud as I feared based on some other reviews. Because it is a powerful air filtration system for a shop, it is unrealistic to expect it not to hear it when it is working.

Anyone who has had a basement flood knows what a nightmare it can be. It takes forever to clear up the water & even longer to get rid of the dampness and musty smell. Do not get me wrong, using a shop-vac helps speed up the drying out process but they never seem to get 100% of the moisture out. Well when our basement flooded again recently, I discovered the solution to that age old problem....a dehumidifier. Once the majority of the flood water was removed, I placed this powerful dehumidifer in the center of the basement and set it to the desired temperature. Due to the size of our basement we needed something with commercial grade power, but most units with the power we were looking for were so much bigger/bulkier/heavier. So when we saw the compact size of this dehumidifier, I was skeptical about whether it would be powerful enough. I am very happy to say that it has exceeded all expectations! The size and weight make it so easy to move from one location to another. The built-in pump makes it convenient to use, you do not have to constantly check on the unit to see if it needs emptied. I love the app....it is easy to set-up, very user-friendly, and a huge bonus feature. It is surprising how removing moisture from the air can warm a room up! Overall a high quality product, I would recommend to anyone!!!!

We bought 4 ALORAIR Air Scrubbers from this company for commercial use. Unfortunately, one broke after 10 months of use.? AlorAir-U.S. send us a new unit right away. Their customer service is so great. They contacted us and solved our problem really quickly. Love doing business with AlorAir-U.S. and definitely in future we will purchase negative air machines only from AlorAir-U.S.

Great industrial strength fan to rid a crawl space area of humidity. It is either on or off then you set the humidity level you want and it will go on automatically when needed. It is really loud and strong and a great performer. Feel safe leaving it plugged in.

We got this for our woodworking shop to keep the dust down. It works great and is not very loud. It has a limit setting so you can set a minimum air quality and when the air gets dirtier than that limit, it automatically turns on, and then turns itself off when the air is below the limit. The remote works great. It was easy to install. We have not had to change the filter yet.

This is an excellent small vent fan for many many types of spaces where humidity build up. This unit has a dial on it so you can dial in the exact humidity you want it to kick on at. Also you can turn the dial to always on or always off. This unit has a nice stainless mounting flange with hardware for different setups. You can use this in attics, crawl spaces and so many other areas where it is not good for humidity to build up. This fan is built very well and a great value.

We plugged this in and could not believe the amount of air it processes so fast. We have quite a setup of a woodworking shop and even though we have a vacuum dust system on the big machines there is still a lot of particles in the air, this machine just eliminates it all! This is a must have!!!!

I have a large sealed crawlspace and within a 4 to 5 hours this unit dropped the humidity levels down from 65% to 45%. Easy install when using the hanging system. The fan noise level on this unit is also lower than my old unit. I do not normally do reviews but I can recommend this unit to anyone trying to lower humidity levels in a home or crawlspace.

I really like this air filtration system. I am remodeling my basement and was looking for something to clean the dust from the air. This air filter arrived very well packaged and ready to go. I hung the air filter from the floor joists using the included hooks and chains. You can also bolt the air filter to the ceiling using included brackets and bolts. Installation was very easy, the unit was light enough for me to install by myself. This air filter is very easy to use, it has two speed modes, a brightness adjustment, and has a timer (from 1 to 9 hours). The remote is also very easy to use and works well. I have been using this air filter for a short while now and it really works well. The air flow is very strong, it intakes the air through all four sides, and the clean air blows out the bottom. This is a strong blower and does a nice job cleaning the air. It is loud, but no louder than other systems I have used before. The only thing I am concerned about is finding replacement filters for this unit. The filter measures 9.5x13.2x1 1/2. I have searched for this size filter and have not found it yet. I am sure it is out there, I will just have to dig a little deeper. Overall, I really like this air filtration system. It is very nice, easy to install, and works well. If you are looking for a nice ceiling mounted air cleaning system, I would recommend this air filter.

the humidistat works reasonably well. do not count on it to give you precise readings on your room s humidity, but gives you a directional read, and therefore automatically triggers the fan when humidity is high. this is a great way to set it and leave it type of situation, either attic or crawl space. my advice would be to pair this with a smart plug switch so you can still override the fan, especially if you are setting up the fan in a space you would rarely go. the noise level is okay, measuring 70 db when i am holding my phone near it. considering the use case in seldom visited locations, i would say this noise level is very acceptable.

I ordered this fan to place in my greenhouse because it gets very hot and very humid very fast. It was easy to install and seems to be doing its job very nicely. I like the programmable thermostat and dehumidistat...it just needs set up and it does its thing on its own! It is smaller than I expected, but if helps with the heat and humidity, the $50 price tag is well worth it and I may order another one.
