I think it's worth it!
By 'Mandel', Reviewed on November 06, 2021
It is a compact and energy-efficient unit. I ran it for 24/7 days because the burst pipe impacted our basement. I thought I would overpay my electricity bill this month, but it turned out to be within my comfort zone. It is worth saying that this dehumidifier does an excellent job of dehumidifying. A week later, my basement was dry. I think it's worth it!
Worth the money!

I am the owner of a musical instrument shop, and the ground in my shop is wet because of the rainy winter weather. I am worried that my instruments will be affected, such as guitar, ukulele, violin, and piano. The damp air was not kind to the wooden instruments. I purchased this dehumidifier after doing some research and following some advice from friends. Overall, I was pleased with its strong dehumidification capability and its ease of operation. The shop floor became dry, and the air seemed to lose its musty smell. Worth with money!
Highly recommend it!

We bought this dehumidifier for our odor basement. Because of the rainstorm, the rain droplet seeps into the basement. So, even though we dry the basement, it still has a musty smell. I was impressed by this unit, and it can be adjusted to the ideal humidity setting to eliminate the moisture and odor. In addition, it comes with a MERV-8 filter that can protect our basement from dust, and I could feel the fresh air in the basement. If you're looking for a compact and durable dehumidifier, I will recommend this one! And you won't regret it.
Solid unit, works great in the crawl space
By 'Ethel', Reviewed on November 02, 2021
For the price, you’re getting a lot here. This thing puts out some really dry air, effectively. Make sure you allow some height difference for the gravity drain. The unit is very compact and had no issues fitting into my tight crawl space.
Works Great!

We love our dehumidifier, and it's not noisy. Also, it works great, and we have it in the damp basement. It works great, and it took my humidity from 70% to 40%. After some dusty work was done, I had to clean the filter, but it was super easy and still works great.
Money WELL Spent!

My friend owns an HVAC business that recommended this dehumidifier to me a year ago, and I finally followed up on it. I wish I would've done it right because it made such a huge difference in how nice and dry the air feels when you walk in the basement now. No more musky smell! I was surprised by how much moisture/water this thing started pulling out of the air shortly after plugging in the little clear drain hose was full and dumping in the sump pit—excellent quality. Money WELL Spent!
Great value for the money!
By 'Edwiin', Reviewed on October 28, 2021
This dehumidifier can extract moisture from the air incredibly fast, and it fits perfectly in my basement. Super convenient and effective. I purchased a different dehumidifier at first, but it did nothing to help. So, I returned it and ordered this dehumidifier. It works well, and it brings down the humidity pretty significantly. I am satisfied with the quality and consistency of this product. Great value for the money.
Highly recommend it!

We have been running the Alorair dehumidifier for only two days, and there is a marked improvement. It works great! It has eliminated the musty odor and other smells coming from the unfinished basement and appears to help the HVAC work more efficiently. Overall this is a really good product, and I highly recommend it.
Working perfectly!

I haven't had this dehumidifier for long,, but I really like this one. This dehumidifier has helped so much with the humidity in my house. The noise level isn't too bad, and I slept all night with the unit on without disturbing my sleep at all. It's compact, and it is working perfectly and getting the job done!
Highly recommend it!
