Purchased in the second half of 2023 and used for approximately two years. The humidifying function was only used for the first 2-3 months, after which I switched to a steam humidifier, so it has not been used since. I was concerned about the odor during use, so I replaced the following with new ones: - Dust collection filter - Deodorizing filter ※ Please check the purchase history in the last photo. There are small scratches due to normal use. Please be aware of this. Also, there are two tears in the mesh net on the back. Please refer to the 9th and 10th photos. Please check the instruction manual here: https://jp.sharp/restricted/support/manual/air_purifier/kc35t7_web.pdf I have wiped down the entire unit with alcohol before listing it. Due to the large size and shipping costs, significant price reductions are difficult, please understand. Shipping may take a little time as I will prepare a suitable cardboard box for shipment.
