What conditions are required for FFP2 mask filter media| KENJOY

FFP2 mask is a kind of sanitary products, which is generally worn in the mouth and nose to filter the air into the mouth and nose, in order to block harmful gases, odors, droplets, viruses and other substances, made of gauze or paper and other materials.

FFP2 mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, when working in a polluted environment such as dust, wearing a mask has a very good effect. FFP2 masks can be divided into air filter masks and air supply masks.

On January 14, 2021, the Information Office of the State Council held a press conference to introduce China's export of 224.2 billion masks in 2020. On February 11, the General Administration of Market Supervision and other four departments jointly deployed to redeploy and strengthen the in-depth promotion of mask quality supervision.

Mask filter material

For the filter material of good protective FFP2 mask, it should have the following three conditions: first, when the mask fits well with the user's face, the filtering efficiency is high, the second is low respiratory resistance, and the third is that the user feels comfortable. Dustproof mask filter materials are made of a variety of materials, including ordinary fabrics, animal hair, non-woven fabrics and so on. A kind of activated carbon felt material is very popular in the national standard.

The structure of the gauze mask has poor compatibility with the human face, and many fine particles that do great harm to us will enter the respiratory tract to the lungs through the gap between the mask and the face, and its filter material is generally some mechanical fabric. in order to achieve high dust prevention efficiency, the only way to increase the thickness is to increase the thickness, and the negative effect of increasing the thickness is to make the user feel great respiratory resistance and feel uncomfortable. The electrostatically treated non-woven fabric can not only block large dust particles, but also the electrostatic charge attached to its surface can adsorb fine dust by electrostatic gravity to achieve high dust suppression efficiency. On the other hand, the thickness of the filter material is very thin, which greatly reduces the respiratory resistance of the user and feels comfortable, thus achieving the three necessary conditions of good filter media mentioned above. With good filter material and scientifically designed mask structure, an efficient and high quality mask is formed.

Fitting effect

The FFP2 mask must be the right size and worn correctly for the mask to be effective. The masks sold on the market are generally divided into rectangular and cup-shaped masks. A rectangular mask must have a structure of at least three layers of paper in order to have a protective effect. Users have to press the wire on the FFP2 mask on the bridge of the nose and spread the whole mask along the bridge of the nose in order to be effective. Can let the child wear a rectangular surgical mask, because it does not have a fixed shape, if tied well, can stick to the child's face. The cup mask should ensure that the mask is dense enough after it is affixed to the face so that the exhaled air will not leak out in order to be effective. When wearing a cup mask, try blowing with your hands over the mask to see if any air is leaking from the edge of the FFP2 mask. If the FFP2 mask cover is not tight, reposition it before wearing it.
