SHARP air purifier KC-50TH4-W, manufactured in 2021, power consumption 54W, 100V compatible. - Model Name: KC-50TH4-W - Power Supply: 100V - Power Consumption: 54W - Year of Manufacture: 2021 - Brand: SHARP Thank you for viewing. The unit functions perfectly, but the filters were dirty and have been discarded. The instruction manual has also been thrown away, but the operation is simple, so I don't think there will be any problems. Please purchase filters separately. Therefore, I am selling it at a lower price. You can probably buy filters on Amazon for around 2,000 yen. Since this is a used item, if you are concerned about odors, I recommend replacing all the filters. Thank you.
