Dainichi Plus HD-9019(W) WHITE (2019 model) Purchased in 2021. Used for two seasons during the winter. The humidifying filter has some limescale, but it has been cleaned as much as possible and stored at home (no smokers, no pets). Operation has been confirmed. It can be used immediately if you fill the tank with water. The main body has slightly yellowed due to sun exposure, but it is still in good condition and can be used for a long time. The original cardboard box is not available, but it will be packed with cushioning material for shipping.
