Air Innovations MH419 vs Levoit Classic 200 Ultrasonic Cool Mist Humidifier

Don't plan on filling this humidifier at the faucet. If you take the water tank off, you can't flip it over in order to prevent drips as you carry it..

I filled the water tank and placed it to work on the Low mist setting ONLY. The tank was empty after exactly 27 hours. Yes, it worked great, very quiet, and efficient for 27 nonstop hours! So, 40? Not in this world, no matter what you do to it. Of course, it will work even less on the Medium and the High settings, but I went with the Low only

The mist outlet points towards the front and cannot be aimed in any other direction. I like the large capacity of this humidifier. I only have to fill it once every 24 hours when I put it on high. It’s not quite the most powerful humidifier that I own—I have another one that puts 1 gallon of water into the air in just 12 hours

I like the clean, sleek look of the humidifier. The quietness with which it operates is also a plus. Occasionally, I can hear the water gurgle but that's because I have highly sensitive hearing. However, it doesn't disturb my sleep in the slightest

This humidifier is perfect for the master bedroom. It is quiet, pumps out enough water even during the winter months when the air is much dryer and is so easy to use and to clean. The top filling beats the heck out of the models at Target that you have to unscrew and inevitably spill water both to and from the bathroom. The antimicrobial and antimildew tech is good

I bought these humidifiers on sale, and they have held up very well. I don't think I will purchase again in the future, though, as I'm sick of cleaning the dang things. They really do get slimy fast. So next time I'll opt for one that has a filter

It was working well until the red mold started to build up as seen in the picture. Tried to clean it with alcohol, vinegar, hydrogen peroxide but just couldn't get between the gaps and there is no way to disassemble the part. As much as I needed the humidifier because I have allergies, I didn't want to breath in the harmful mold.

It is easier to clean than my other humidifier, but it does still have some hard to reach places. I would repurchase this over my other humidifier though so I think this is worth it.
