Introduction to the classification of Disposable face mask
Feb 28, 2022
Disposable face masks are generally divided into the following categories:
1. Ordinary medical masks have low filtration efficiency for particles and bacteria, lower than medical surgical masks and medical protective masks. It can be used for one-time hygiene care in ordinary environment, or suitable for the barrier or protection of particles such as pollen.
2. Medical surgical masks are divided into 3 layers. The outer layer has a water blocking effect to prevent droplets from entering the mask, the middle layer has a filtering effect, and the inner layer has a moisture absorption effect. Protects against viruses and stops the spread of blood, body fluids and splashes.
3. Medical protective masks are the familiar N95 masks, which are suitable for the protection of airborne respiratory infectious diseases.
In general, compared with ordinary medical masks, medical surgical masks and medical protective masks have a good barrier effect on respiratory infectious diseases, but in general, medical protective masks have the highest level of protection. Generally speaking, it is enough to wear a medical surgical mask. Some people think that wearing multiple masks at a time will provide better protection, but in fact, it is not much different from wearing one mask.
