About Qenza
Qenza is the brand of 清择科技 (Qingze Tech). The company makes a small set of air products, starting with Air One, a HEPA purifier for one mid-to-large room.
Air One is not a medical device. The public site qenzaair.com is planned and not connected yet. This shop stays on hd03dn-5q.myshopify.com until that domain is attached.
