Dyson Humidifier MF01 White Used for about 7 years, so there is a sense of use. I have washed it as much as possible at home, but there is some dirt that cannot be removed, such as on the inner parts. Cleaned with citric acid in March of this year. It humidifies well and there are no problems with use at all. Accessories: Remote control *Includes shipping, will be sent via anonymous delivery☆
