Masks work by integrating physics, chemistry and biology. They use fiber meshes to physically block particles, while electrostatic attraction traps smaller pathogens. Biology defines the virus size and math models the airflow efficiency.
A mask functions through a multidisciplinary approach. Physics explains how fibers physically block large particles and use electrostatic attraction to trap smaller ones. Chemistry determines the properties of the polymer fibers, while biology informs us about the size and behavior of viruses. Mathematics allows us to model airflow and calculate filtration efficiency. By integrating these fields, masks create a complex barrier system that effectively filters out harmful pathogens from the air we breathe.
