Panasonic Jiaiano Spatial Disinfection and Deodorization Machine F-ML4000B-W This is a new, unopened product. The color is white. It's more compact than previous Jiaiano models, fitting in an A4-sized installation space. The disinfection and deodorization performance covers a wide area of 18 tatami mats (approximately 30 square meters). It features an easy-to-wash flat tray, and the drain frequency is only once a month, improving ease of maintenance. I am open to some price negotiation, so please feel free to inquire.
