Children’s masks ptfe filter material has a protective effect of greater than or equal to 90% and a particle filtration efficiency of greater than or equal to 90%. It is a children’s mask filter material with strong protective performance and can prevent microorganisms, droplets, dust, particles and other particulate matter. Inhaled.
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.
In addition, the internal respiratory resistance of children is inherently greater than that of adults. Therefore, on the premise of ensuring the protective effect, in order to make children enjoy relative comfort when wearing masks, reducing the inhalation resistance is the most important requirement of children’s masks.
The filtration efficiency of the ptfe filter material of children’s masks can reach more than 95% for 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.
In addition, the PTFE membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception (pore size interception method). The interception rate will not be attenuated due to moisture in the exhaled breath. Compared with ordinary melt-blown cloth masks, the protective effect of electrostatic adsorption is more stable and lasting.
