Smart App Control

Wi-Fi Connect

Remote control of APP and the device can be done via Wi-Fi. But before that you need to know some tricks for pairing:
1) Before you connect, you need to be close enough so that the signal won't break on the wall or insulation of the house
2) Buy an extra Wi-Fi mesh or repeater to increase the signal strength to make the pairing of the devices more successful
3) The app currently supports only 2.4 GHz network. Please turn off the 5 GHz network on the router to make the connection work more smoothly.

Direct Connect

When you connect your device via the direct connection mode of APP, you only have an effective distance of 40m. Therefore, it's fast and easy in a network-free environment.

Please note

Download your app here, but APP is currently not working for iOS versions higher than 15.0

I recently purchased and have had the opportunity to use my new AlorAir dehumidifier. I am very impressed with the way the unit is working. It certainly is also one of the coolest looking units I have ever seen. Seems very solid and well made. I love the Wi-Fi access. That is one of the main reason I bought this one. I would recommend this unit.
Even better than expected!!

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 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!!!!

Great little dehumidifier

From the Amazon

I work in a water damage restoration company. This dehumidifier is great but requires 2 modifications. 1. Put a clip on the male end of the drain hose so the hose does not fall back into the machine. 2. Extend the drain hose to 40 feet. We added more tubing and it works well. Heat Level: excellent Screen: easy to use Maintenance: not known yet Build quality: similar to Phoenix but requires some modification. Ducting ability: has the duct ring so you can add layflat to it easily. Great feature. Maneuverability: easy Form factor: great Stacking: I only have 1 but I think it will do well. Durability: decent. Exactly what is needed in water damage restoration.

Our basement was so damp, and we needed a dehumidifier. This dehumidifier was the right size, and we liked and trusted the brand name, so we decided to give it a try. It is just what we were looking for, and it works so well in removing the dampness from the basement. We are glad we chose this one. We are very satisfied.

Dehumidifiers are a game-changer. Because of the cold weather and heating inside our home, we have had excessive moisture build-up, leading to condensation and mold build-up. Thanks to Alorair, we were kindly gifted this dehumidifier to help reduce this problem, and I can not believe how well it works! There is zero to little condensation in the room and dramatically less mold build-up! I can’t believe the fantastic results!

I purchased this dehumidifier in my workshop to help keep the moisture levels down. I got this plugged in, and it started to work right away. It's so quiet you don't even know it's running! I can feel the air is drier and not as sticky.
