Thank you for viewing. This is a Zojirushi steam humidifier. I purchased it in 2020 and used it for two seasons. I haven't used it in the last few years and have stored it in a dark place. Please refer to the following for the capacity and size. This is a humidifier that boils water and humidifies with steam. Maintenance is also easy, as you only need to use citric acid, making it very easy to use and keep clean. Continuous humidification is possible for about 8 hours, depending on the operating mode, and it is very convenient as you don't need to refill the water frequently. It also has a child lock, making it perfect for households with small children. It has an automatic shut-off function in case of tipping, which activates and automatically stops the power supply to the heater if the unit is tilted or tipped over during use. It has been cleaned with citric acid. Simple cleaning has been done, but please understand that it is cleaned by an amateur. Although it is a used item, I think the condition is very clean. Please purchase it if you understand that it has been in someone else's possession.
