Why I founded Wynd, an air quality startup
Raymond Wu

Hi Ray,

I am from Beijing and know exactly know what you are talking about the changes in the air pollution. Since the metro cities have huge amount of cars, the smog contains large portion of the ozone, which shows the foggy colore in the air. I understand your product mostly for particles, have you done the test for ozone filtration which you may see some supprise.

Thank you for your great job!
