We are leaving China and have our Blueair 400 Series Air Purifier for sale. Selling for 2200RMB. It is in great working condition, it just needs its 400 series filter replacing (you need to do this every 6 months). You will need to buy this separately. Does not come boxed, and you will need to pick up from our house near guloudajie subway station (Line 2)
If you are interested, please send me a message on wechat. I have other stuff for sale, so if you're interested in what else you can pick up please take a look at my other postings or message me
