I used to use the ultrasonic ones and this is the first evaporative humidifier I got. It looks to me that it is more efficient but also noisier comparing to my old ones. Plus I dont need to clean the water tank very frequently like once per two days. The humidifier it self is larger than I expected. In terms of cleaning, I have to carry it to the water sink and if you dont have a large enough sink it could be somehow hard to clean. It is pretty easy to use from my perspective, I just pour tap water in to the water tank and that is it!

I am giving the Airdog humidifier 5 stars but in reality it is more like a 4.5, it is great but not perfect. That said, prior to the airdog I have owned 2 Levoit misting humidifiers and they were ok but I really wanted an evaporative humidifier so I took a chance on this relatively new product. Compared to the Levoit humidifiers I was surprised how quickly the Airdog is able to humidify my small home-office. As you can see in the attached pic the Airdog significantly increased the humidity in the room in about an hour or less and it did it with zero mist. I would say it is as effective or more effective than the misting humidifiers. Before purchasing the Airdog I thought that evaporative humidifiers were a gimmick or less effective, so I was really pleased to see just how good the Airdog worked and how quickly it raised humidity.As to the negatives: There is a few features on the Airdog that are useless, and some features I wish it had. One of the features I really miss about the Levoit humidifiers was the ability to control the humidifier remotely anywhere through the app. With the Airdog there is no app and you can only control it on the device itself or via the included remote control. Another feature I really wish it had was the ability to memorize your set humidity level after turning the device off/on. Unfortunately every time you turn off the device you have to re-select your desired run type (low, high, or auto) and if you choose auto you have to re-set your target humidity , which is extremely annoying. Instead of giving us this basic memory function Airdog decided it was better to give us a rainbow LED light show that does NOT give you the option to select one color and keep it there. Thankfully you can leave the LED lights off completely. To avoid having to re-select and reset your humidity target you can just leave the humidifier running all the time (which I do), but the downside to that is you will have to refill the humidifier like 2-3 times per day whic.

Unfortunately the clear plastic water gauge leaked water while filling the container. I filled it to the proper level but the rectangle shape shield leaked. I didn’t return it because it’s something I could repair with some water seal. So I did and it works fine.

I am really enjoying my Airdog humidifiers. They are nice and quiet, easy to maintain and look great. The shipping was very quick and customer service has been very helpful with any questions. Thanks Airdogs!

Got it from Airdog Amazon very quick, been using it for almost a month. I'd like to say this is really high quality product of Airdog. I love their brand, always offer premium products! This Mist-Free Humidifier is working very well, I feel moisture and much clean air breathing in my room. Also it works so quiet at night, no noise bothers me! And i love the rainbow light, so cute!!!
