ASOM Ultrasonic Cool Mist Humidifier

Here’s what I found on Amazon

Any thoughts on using this for an acoustic guitar room (as opposed to using individual case humidifiers for each instrument)?

Can one turn the “night light” off altogether? I don’t need a lighted humidifier.

Yes

It doesn’t have an auto shut-off feature, so you can’t maintain the 49-51% humidity that acoustic instruments need. You’ll just need to keep you eye on the relative humidity of the room to make sure it doesn’t get too humid.

Just received mine and it was nonworking out-of-the-box. Have asked for return authorization.

I also received mine yesterday and plugged it in and ran it overnight. Woke up to find no water had been used whatsoever so mine is also not working, out of the box.

Yikes, I’m sorry to hear that. If you haven’t already, please use the Customer Service form and they’ll be happy to help.

Same here. It worked for one day and then hasn’t worked since then. I can’t figure out what is wrong. I just put in a return request as well.
