This is the Dainichi hybrid humidifier "HD-154". It's a powerful model with a large 12L tank, capable of humidifying spaces up to 42 tatami mats (approx. 740 sq ft). It can effectively humidify large spaces like living rooms and offices. The hybrid system automatically switches between evaporative and warm-air evaporative methods, efficiently maintaining comfortable humidity while saving on electricity costs. The filter structure is also robust, and it's easy to clean. The area where water collects is clean because it uses a tray! Also, two spare trays are included, so you can continue to use it cleanly! Made in 2020, it's in overall good condition. There is some yellowing mainly on the back and a little on the sides due to use, but the front and top are clean. Operation is good. ※ See photos 6, 9, and 11. Operation has been confirmed, and it's ready to use immediately. #Dainichi #Dainichi #Humidifier #HybridHumidifier #HD154 #LargeCapacityHumidifier #42TatamiMatCompatible #HumidifierGoodCondition #Appliances #DrynessPrevention
