This is a Zojirushi humidifier (2019 model). I bought it and only used it for one season before putting it away. It was stored without being in a box, so I washed it, but it may not be completely clean. However, I think it's in good condition. No box or instruction manual. What do you think? I have confirmed that it works before listing it. I washed and wiped it, and let it dry for several days, but there may be some water droplets remaining. Please understand.
