Let's start with the basics. A medical mask, which is on rubber bands and rectangular, two- or three-layer, which has recently become a terrible shortage for some reason, will not save from the Chinese coronavirus (here and further — as well as from the banal SARS)!

Firstly, viruses can penetrate through the filter element of such a mask. Secondly, it does not fit tightly enough to the face, so the path for viruses is open. Remember, write it down, tell it to your neighbors and don't spend money on masks that have gone up in price in some pharmacies dozens of times.

In other words, it should be worn if you are ill, but are forced to contact healthy people.

The medical respirator fits much better to the skin of the face, it has a special aluminum plate for maximum contact with the skin in the area of the bridge of the nose, and it is fixed on the back of the head with special adjustable elastic bands.

According to it, respirators or filter half masks for protection against aerosols are divided into three classes depending on their filtering efficiency: FFP1 (low efficiency), FFP2 (medium efficiency) and FFP3 (high efficiency). The penetration coefficient through such half masks should not exceed 25%, 11% and 5% for FFP1, FFP2 and FFP3, respectively. All of them are more suitable for protection against viral infections than surgical masks.
