※ Discounted price for a limited time only. The price will go back up soon. ※ Purchased new around 2021 for 77,000 yen (tax included). The filter was also purchased officially for 7,700 yen. Used for two seasons, summer and winter, so there are some scratches and minor marks from normal use. It has been cleaned. It can be used as an air purifier with a fan in the summer and as an air purifier with warm air (heater) in the winter. I threw away the old filter I was using, but I had a spare, so I'll include a new, unopened one. I was using another air purifier, so this one has been stored in the closet, but I'm getting rid of it as part of a year-end decluttering. Operation confirmed. Of course, the remote control is included, but you can also use it by linking it with the app on your smartphone even without the remote control. It tells you how polluted the air is with numbers. When not in use, the remote control attaches to the top with a magnet, so you won't lose it. No smoking, no pets. The instruction manual is not included, so please download it from here. You can view it on your smartphone or computer. https://www.dyson.co.jp/medialibrary/Files/Dyson/Support/downloads/JP/UserGuides/EC/Pure-Hot-Cool/HP04_Manual_JN96056.ashx Dyson Pure Hot + Cool HP04 Black (dyson HP-04) [Product Features] Automatically detects and analyzes particulate matter and harmful gases in the air and provides real-time information.
