MIT start-up Infipure develops invisible nose air mask
Infipure has been selling the invisible air mask on Taobao for two weeks. They offer three sizes and are pretty cheap.
There is not a lot of technical detail available yet. So it is not clear how effective the masks are. How often the user should change the mask is also unclear. But it is worth trying. The air cleaner and air mask markets are booming because the general public in China is now very concerned about air pollution. I am overall pretty enthusiastic about the idea of Infipure. The start-up is offering a short term solution to a public health emergency. And I am also glad Infipure’s founders are co-MIT grads!
