I've lowered the price today. Please read the description and consider purchasing. Thank you. ◎ Previous seller purchased new on December 24, 2024 ← I received it on January 13, 2025, and it's unused. ◎ EE-RT50-WA ◎ Filter-free ◎ 2024 model ◎ Steam type ◎ Wide-mouth container ◎ Triple safety design ◎ For rooms up to 13 tatami mats (approx. 21 square meters) The previous seller purchased it on December 24, 2024, and only used it temporarily at the end of the year. I received this beautiful item for 20,000 yen on January 1, 2025, but I purchased it without considering the size of my room, so I haven't used it once. The included 30g of citric acid for cleaning is also included. This humidifier is filter-free, easy to operate, and features a wide-mouth container. ♦ It was sent to me in its original box, so the box is not in perfect condition. Please understand. ♦ Description from the previous seller → There is some limescale, but please clean it with the included citric acid. See the last photo*. I think it's in good condition (the limescale should come off with the citric acid).
