This is a DAINICHI hybrid humidifier, model HD-RX318. I no longer need it because I purchased a steam humidifier. Condition: * Purchased in 2020 * Instruction manual included * Original box and styrofoam packaging included * Evaporative filter is not included (requires separate purchase) It was used for about 4 years, only during the winter. I disassembled and cleaned it last winter, so I think the inside (fins, etc.) is relatively clean (used for about 1-2 months after disassembly and cleaning). The evaporative filter is not included as I ran out of stock. You can search for "HD-RX318 filter" on Amazon, etc. (Genuine filter: 2310 yen, compatible filter: 850 yen and up). Based on my experience, I replaced it about twice a year while washing it (using compatible filters). The antibacterial effect of the "Ag+ antibacterial attachment" installed on the lid of the water tank has likely expired. I have washed and thoroughly dried it, so there should be no harm, but I recommend purchasing a new one if you are concerned. \* Please consider this item as a used product. Other: * The outer box will be packed in cardboard. * Anonymous shipping * Instant purchase OK #Humidifier #DAINICHI #Hybrid
