Children have a strong metabolism, and their metabolic levels and oxygen requirements are close to those of adults.
Due to their physiological characteristics, children’s lung capacity and tidal volume are smaller than those of adults.
In order to adapt to metabolic needs, the body can only meet them by increasing the respiratory rate, so the younger the age, the faster the respiratory rate.
Furthermore, the internal respiratory resistance of children is inherently greater than that of adults. In order for children to enjoy relative comfort when wearing masks, reducing the inhalation resistance is the most important requirement for children’s masks.
The ptfe filter material produced for children’s masks can filter more than 95% of bacteria and PM2.5 particles in the air, reaching the filtration standard of KN95 masks.
The extremely high porosity and ultra-thin thickness of <5μm give it better air permeability, low breathing resistance and comfortable wearing.
