N95 masks are better in terms of protection ability, and medical surgical masks are more comfortable in terms of comfort. n95 masks are also divided into industrial dustproof and medical protection, and medical protection masks are of the highest level, but for the daily protection of the general population, as long as wearing norms, whether using N95 masks or medical surgical masks are sufficient. the main differences between N95 masks and medical masks are the following: 1. bacterial filtration Efficiency: N95 masks and medical surgical masks with ≥ 95%; 2, particle filtration efficiency: medical surgical masks can filter ≥ 90% of the 5μm particles, while N95 masks can filter ≥ 95% of the 0.3μm particles; 3, non-oily particles filtration efficiency: N95 masks ≥ 95%, medical surgical masks ≥ 30%; 4, mask layers: medical surgical masks can prevent the spread of blood, body fluids and splashes. body fluids and splashes from spreading. Standard surgical medical masks are divided into three layers, the outer layer for the water barrier layer, can block the splash liquid; middle layer for the filter layer, can effectively block particles; inner layer for the water absorption layer, can absorb the wearer’s mouth and nose water gas. n95 mask layers are generally greater than 3 layers, usually 4-6 layers, the role of the outer and inner layers and surgical masks are the same, but the middle layer of different brands have different layers, the role of filtration.
