Fujitsu Plasma Ion UV Humidifying Deodorizer As shown in the reference brochure photos, the main selling point is zero filter replacement cost. Power on and operation confirmed. It's a humidifying deodorizer, but the humidifying function has not been used. Although cleaned, there are some scratches and stains on the filter and the main unit. There are no problems with use, but please understand that this is a used item before purchasing. I have two units, so if you would like to purchase both, I will change the price. Please let me know in the comments section.
