Types of Masks
Masks have been around for over hundred years and have been used in various industrial, healthcare or domestic settings. Over time, advances in manufacturing and material science have created a wide array of masks, with different filtering capabilities.
The Corona virus is between 0.06–0.14microns in diameter or 60-140 nanometres. Contrary to what we may think, viruses this tiny are easier to filter than those that are larger than 0.3 microns, because they follow a Brownian motion (random zig zag) and therefore trap more easily inside filters.
double filter gas mask
If you have a thin, single-layer double filter gas mask, then double-up. Or triple-up. The multiple layers work to filter those infamous droplets that carry the virus.
And make sure your double filter gas mask fits properly. It should cover the bridge of your nose, the tops of your cheeks, the sides of your face and under the chin without significant gaps.
