I urgently purchased two new units in 2022. After using them only a few times, they were put into storage and have not been used since. I have confirmed that they power on. Also, although I am not a professional, I have disassembled and cleaned them as much as possible with a screwdriver. The HEPA filter and carbon filter have not been replaced since I purchased the units. As these are used items, there are some signs of wear and tear, such as scratches and dirt. Therefore, I am offering them at a lower price than the market value. I would appreciate it if you could consider purchasing them, understanding the above points. ※ If you purchase both units together, the price will be 13,980 yen, including shipping.
