With the way I had to rearrange things to get the new tank not on the soft spot on the floor, the humidifier now has to sit on the hutch of my desk, which is fine, except that it echoes and makes it sound even louder. I've messed with all 3 of the humidifiers I have, and the quietest one is also the crummiest one. I literally have the pump enclosed (mostly) in an old coffee jar with a pillow taped around it. It's still fairly loud. Any tips or tricks for making a humidifier quieter? Or any particularly quiet humidifiers?
