Model Name: HD-RX517(T) Power Supply: 100V Power Consumption: 170/170W Humidity Settings: 70%, 60%, 50% Operation Panel: Digital Display Year of Manufacture: 2018 Thank you for viewing. This is a hybrid humidifier from Dainichi. The filters were replaced with genuine filters this season (December 2024). It has been properly maintained, so there is no mold. There may be some minor water stains, but there is nothing that looks obviously dirty. I think it has relatively little wear and tear, but please judge from the photos. The operation itself is still working, so there are no problems.
