This is the popular Zojirushi steam humidifier, model EE-DE50-WA (white). I purchased several of these for my new home this season, but after using them, I found the humidification capacity to be too high, so I no longer need one, which remains unopened. It has been untouched since it was delivered by宅配 (courier service) and has not been put away. I will ship it in its current condition. This model uses the power of hot water for clean humidification, and it's very helpful because it's easy to clean. It's also a characteristic of this model that it is a heating type, so it is difficult for bacteria to breed. 【Product Details】 ・Model Number: EE-DE50-WA ・Humidification Method: Steam式 (Steam) ・Applicable Area: Approximately 13 tatami mats (8 tatami mats for wooden construction) ・Size: Approximately 24 x 27.5 x 31.5cm
