Hybrid Humidifier UF-HV124R-W Used for one season. Originally cost around 40,000 yen. The filter has limescale stains, so it might be better to replace it (although there's no problem with using it as is, as I've cleaned it with citric acid, etc.). Humidification method: Hybrid (warm air vaporization/vaporization) Condition is as shown in the photos.
