Results of a study on mask efficiency
The results of a recent study by researchers at Duke University in the United States on the effectiveness of masks have been unveiled.
N95 masks stop 99.9% of the droplets emitted when speaking. Three-ply medical masks stop 90% of the particles emitted, while cotton masks are rated between 70 and 90% depending on the number of layers.
They are therefore an effective solution in the fight against COVID-19, and their safety is increased when everyone wears them!
