IRIS OHYAMA Iris Ohyama Humidifying Air Purifier Made in 2019, used for about a month and then stored in the attic for several years. Operation has been confirmed before listing. Disassembled and lightly cleaned. The product has some yellowing, but in my opinion, it's not very noticeable. I disassembled and cleaned the filters inside, but since time has passed, you can use them as is if you don't mind. If you are concerned, please purchase new ones. The filters themselves look clean to me, but that's just my opinion. I only used it for about a month, and it was stored in the attic, so there are no visible scratches. I have confirmed that it works without any problems before listing. Please understand that this is a used item. Those who are sensitive to such things or are looking for a new item should refrain from purchasing. Regarding Shipping To reduce shipping costs, I will ship it with only bubble wrap, without a cardboard box. Of course, I will pack it to prevent scratches and damage. Only those who understand this can purchase. Thank you.
