Thank you for viewing. This is a SHARP Plasma Cluster Humidifying Air Purifier, model KI-LS50-W. The humidifying function has not been used, so there is no mold. I purchased it new, and the "unit replacement" lamp is currently lit, so it seems I've used it for exactly two years. (The unit replacement lamp indicates that it's time to replace the Plasma Cluster ion generation unit.) Therefore, I will include a new unit that I purchased for replacement. (Sharp genuine product, 3,000 yen) It's a bit difficult to see, but the left side of the unit in the second photo has become cream-colored due to sun exposure or aging. Also, please be aware that there are multiple small scratches from use. Regarding shipping: It is large and weighs about 10kg, so I plan to request a pickup from Yamato. Therefore, depending on when you purchase it, you may have to wait about a week. Please understand.
