I used this for the first maybe 6-ish weeks constantly, but I think it is not meant to run 24/7. The motor has started making a loud noise when you turn it on, like it’s going to take off, but after 30 secs or so the noise stops and it runs just as quietly as ever. So now I just run an 8-hr cycle once or twice a day in a very small bathroom. I had hoped it may generate a little heat as larger dehumidifiers have done in the past, or at least dry out the room so it felt a little warmer, but it doesn’t. Still, my towels dry faster, and it’s already the 3rd dehumidifier I’ve tried, so I’m keeping it.
