This is a DAIKIN humidifying air purifier. It has been disassembled and cleaned, making it spotless inside. It features Streamer technology and a compact, space-saving design. I have been using it since January 2018 (manufactured in 2017), but I replaced the dust collection filter (images 11-12) in March 2022. The silver ion cartridge for the air purifier (image 6) was also replaced in January 2025. There are no defects or abnormalities, and it is fully functional. I also disassembled and cleaned it today (December 31, 2025), including the fan blades (images 16-17), so it's almost like new. I don't think other sellers can show the inside with pictures, but I've taken pictures from the air intake to the fan, so please refer to them. I believe it's usually impossible to clean this thoroughly. Normally, with prolonged use, the ion cartridge gets old, and the air can smell, but I've replaced the parts and kept it clean, so there's no such smell. I don't smoke, and I don't have any pets. There is some slight limescale buildup in the water reservoir of the humidifier. I have cleaned the small parts with citric acid, but please understand. Also, due to aging, the mesh part of the dust filter in the lower center (image 15) is frayed. Please feel free to ask if you have any questions. - Model name: MCK55T-W - Color: White - Power supply: AC 100V - Power consumption: 6-58W - Size: Width 27cm x Depth 27cm x Height 70cm * Instruction manual, warranty card, and remote control are also included.
