Used for about 2 years and stored at home. ●Operation as an air purifier has been confirmed to be problem-free. ●This is a used item, so please refrain from purchasing if you are sensitive to such things. ●There is no original box, so I am considering shipping it wrapped in bubble wrap and then wrapped in cardboard.
