Highly recommend it!

It is an excellent dehumidifier. It is easy to use, and I'm delighted with my purchase, and I'm glad I took the chance. It doesn't seem to give off too much heat or noise. It is quieter than my a/c.It runs great and makes a very noticeable difference in the humidity. I can work in the garage now with a fan running and feel very comfortable.
Highly recommend it!

I bought this dehumidifier because it is the newest model, and it has a more up-to-date controller panel. Before I install it in the crawl space in my house, which is a lot of work to do, I am testing the dehumidifier and remote controller in my living room for a few days to evaluate its performance. The unit was easy to use, and it seems that everything is working as described. So far, I will recommend it.
Get the job done!

I have a townhome in the midwest. It is pretty humid in the summer. So, I bought this uint want to remove the extra moisture. In 24 hours, it has dropped the RH from 71% to 41% in the basement. 68% to 54% on my main story. Even though I don't have a gauge for the floor, the musty smell and clammy feeling are gone.
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!
By 'Vivien Bartlett', Reviewed on November 01, 2021
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!
By 'Zachary Ben', Reviewed on October 29, 2021
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.

Hi Tom, this unit has a smart WiFi control function. So, this unit can MONITOR THE RESTORATION PROCESS ON THE GO! Our free AlorAir mobile app is included with the unit upon purchase.
Answered by Larry
A further question: Oh, so WiFi is the difference between this Gold model and the standard HD55 model - I was looking hard on-line and in the respective manuals for what the difference is (since there is also a difference in price). No mention of WiFi at all, except in this Q&A! What are the instructions for setting up and using the WiFi, and how does that integrate with the panel controls and remote control? This is a pre-sales question.
