Understanding Mask Protection and COVID-19
Why Masks Matter
Face masks are one of our most effective tools against COVID-19 transmission. They work by filtering airborne particles and blocking droplets from coughs, sneezes, and normal speech. Research shows that widespread mask adoption can reduce transmission rates by 50% or more.
Effectiveness Factors
- •Filter Efficiency: Percentage of particles blocked
- •Fit: Proper seal around face edges
- •Material: Quality and layering of filter material
- •Maintenance: Regular replacement or cleaning
