Thank you for viewing! ★Zojirushi EE-RR50-WA Steam Humidifier★ 3.0L White Made in 2021 I used it carefully, cleaning it regularly with citric acid. Actual operating time was about a year in an apartment. I'm selling it because I've used it less since moving. There is no dirt on the main unit, but there is limescale inside. Operation confirmed. No problems. The humidification power is amazing. I will ship it in the original cardboard box with the instruction manual. I'll also include the Amazon reviews. It's popular for being easy to clean and maintain. It's highly rated for being filter-free and easy to care for, and for being able to humidify just by adding water. There are also comments that it provides peace of mind in terms of hygiene, with a low risk of bacterial growth. Also, people feel safe because it has a function to lower the steam temperature. On the other hand, there are complaints about the sound. Some people point out that the sound is noticeable at first until it boils, but it seems that the electricity bill may be high because the water runs out quickly. Regarding the design, although it is not fashionable, the satisfaction level is high.
