Purchased new at an electronics retailer in 2021. I don't remember the exact purchase price, but I think it was a little over 20,000 yen. Used it a few times, and cleaned and washed the filter and around the tank each time. As it's during the infectious disease pandemic, I'd like to sell it while it's still clean. Please refer to the 15th photo for the size. Operation confirmed. It has been cleaned and disinfected again. It will be shipped in a cardboard box, wrapped to prevent water damage, and secured with tape.
