There are no particular operational issues. Since I purchased it overseas, the shape of the power outlet is different, but I will include an adapter. There is some dirt, but it's as shown in the photos. The fan became a little noisy, so I took it all apart and cleaned it. I recently replaced the filter. It's an overseas model, and I'm selling it at a low price, so I hope you understand that I cannot lower the price any further. Direct pickup only in Mitaka City, Tokyo.
