Nasal Lung-Pro
5 times higher filtration efficiency than that of masks

Humans have been using mask for over 200 years but seldom doubt its effect. According to research, low-density mask has low filtration efficiency and same for high density mask, as air could travel freely from the space between your face and the mask. With micro space imagination, BROAD invented the Nasal Lung-Pro, it has a filtration efficiency at least 5 times higher than that of a mask and is more breathable and comfortable, even cheaper. As almost the tiniest product, it will bring changes to the most people in the world. The only flaw is that people might not get used to the look of the Nasal Lung-Pro on their face. However, we believe humans will eventually be aware of the inefficiency of mask.
