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 stored away. It will be shipped in its original condition. This type of humidifier 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 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
