YUASA PRIMUS Steam Humidifier YHB-M430F(W) [Steam Type] Made in 2024 Manufacturer Release Date: Mid-October 2024 Used only at night for about 2 months. If filled to the maximum, it rarely ran out of water overnight even when used on the high setting. I washed it with water almost every day and used citric acid about 4 times a week to prevent limescale buildup, but there is some limescale present. I have cleaned it at home before listing it, but please understand that there may be some limescale stains. Since it is a steam type, there is no odor.
