Why do I design the nose mask? January 15 2025, 0 Comments
I felt there was a smell at airport in Beijing in spring, 2015, The face mask can not brock the smell. I changed to wear the activated carbon face mask, which is better. I had the pain in chest when I breath in 3rd day. Then, I started to have dry cough. My trip as 10 days in China.
I had to see Dr. after in 2 months after return Toronto. I spent C$200 for treatment. Then I started to search the information about the face mask. I found there is a air leaking promblem on face mask, VOC's in air pollution.
The both activated carbon fibre and HEPA can treat the air pollution, remove smoke, ash and more. The face mask should be no air leaking at all.....
My draft of drawing is coming out in 2017, The first sample of Rocky Air Nose Mask is available in summer, 2020.
