ובכל מקרה לא רלננטי כי הגודל של החורים במסכה הוא פי הרבה מהגודל של הוירוס.
The holes in standard cloth or surgical masks are generally much
larger than a single coronavirus particle. However, masks are still effective because of two key mechanisms:
- Droplet Transmission: The virus primarily spreads via respiratory droplets produced when an infected person coughs, sneezes, talks, or breathes. These droplets are much larger than a single virus particle, typically 5 microns or more, and are effectively blocked by most mask materials. The mask material acts as a barrier to the moisture carrying the virus, which wicks into the mask and is trapped.
- Filtration Mechanisms Beyond Sieving: Masks do not work like a simple sieve. At a microscopic level, particles in the air move in an erratic, zig-zagging fashion (Brownian motion), increasing the chance they will collide with and be trapped by the mask's fibers. High-quality masks, like N95s, also use electrostatic absorption to draw and trap particles onto the fibers
