I really like this one, despite some bad online reviews. We’ve had ours for years with no issues (I suspect that some people may not realize that if the filter becomes dry it will take a few minutes for the vapor to come out, so it may seem like it’s not working, but we may have just lucked out with a good one). I keep it on my bedside table. It’s completely silent and doesn’t harm our hardwood floors. This one is pretty small and may not be powerful enough for your needs, but I notice a big difference every winter when I bring it out. Hope that’s helpful!

Do you have a model name/number for that Homedics humidifier?

Edit: I think I found it - https://www.homedics.com/totalcomfort-personal-ultrasonic-humidifier/

How often do you need to clean it?

I clean mine every time I use it. I didn't list mine, although I like it, because it is not totally silent. It doesn't bother us, but I can here it. However, I have felt every surface (wood floor, nearby wood bedside chest and wall) to make sure the mist does not harm any surfaces. Haven't felt anything but I put an aluminum pie-plate under mine just-in-case, as it sits on the floor.

DD had one like this to use with the children. She likes it because there is really nothing to clean. You use a glass of water each time. I don’t know that this specific one is the one she had, but it is similar. They are also sold Amaz(on)ing site. <is that too subtle?

Terezosa: yes, that’s the one I have.

I pretty much run mine 24x7 in the winter. I fill it every night before bed and will top it off at some point during the day. I‘d estimate that I wipe it out every few days and really clean it every few weeks. If I recall correctly, it comes with 2-3 replacement filters and they last a very long time. We have hard well water, but I’ve not noticed that it’s ever “dirty” when I wipe it out. I actually purchased this one because of how easy it is to clean. Our prior one had too many parts and crevices that were difficult to clean.

ETA: Just read this on the Homedics site, which may explain why I’ve never noticed it being dirty when wiping it out. And it does come with 3 filters. “The Clean Tank Technology offers your stylish gray tank protection against mold and mildew with 3 included wicks.”
