What is the wildfire smoke? small particle, toxic! June 09 2023, 0 Comments
The wild fire burned everthing: trees, homes, glass, trucker, cars, animals and more. The visible distance is reduced.
So the wild fire smoke is black with smell and odor, it is toxic. The smoke is flying thousand KM away. The are small particle less them PM2.0 will go into blood. It is harmfull for your body.
I had cough in third days during my 7 days business trip from Canada to China in 2013, the visible distance was less than 2KM in Taiyuan. There was very high air pollution in China. I feel to wear activated carbon face mask is much better than medical face mask. The medical face mask is uneless.
I had dry cough for two months in Toronto after return from China. I had to see my family doctor. I spent C$200 on drug.
Therefore, I started to do research on face mask, and decide to make the nose mask in 2017.
