I have a few Blueair 203 purifiers that are brand new and still in the box. If you would like to buy them I will sell them for 2700 RMB each. (they are originally 3500 RMB each).
If you are interested in a different model or buying more please feel free to contact me at any time. I can tell you where to find any of the best purifiers at the best prices. My contact information is listed below. Thank you, and I hope to hear from you soon!
