What is FFP2 mask| KENJOY

You can't go out without wearing a mask, but what do most people know about them? The following is a description of FFP2 masks by the wholesale supplier of masks.

In fact, the European standard FFP2 mask, one of the EN149:2001 standards, is a disposable medical protective device with a minimum filtering efficiency of 94% or more and can block harmful aerosols without being inhaled. The FFP2 mask came in second, with the highest grade being FFP3 (less than 97 percent filtration) and the lowest grade being FFP1 (minimum filtration).

What is FFP2 used for

1. Personal protective articles are designed to prevent or reduce dust in the air from entering human respiratory organs, so as to protect life safety;

2, material: anti-particle mask mostly uses two layers of non-woven fabric inside and outside, the middle layer of filter cloth (melt-blown cloth) structure;

3, filtration principle: filtration of fine dust mainly rely on the middle of the filter cloth, because the melt-blown cloth has electrostatic characteristics, can absorb positive small particles. Due to the adsorption of dust on the filter element, the filter element can not be cleaned with static electricity, and the filter element needs to be replaced regularly.

4. Note: The use of dust masks at home and abroad is quite strict, among which the anti-particle mask belongs to the first level, which is higher than ear muffs and protective glasses. The more authoritative testing certification has the European CE certification and the United States NIOSH certification, and the United States NIOSH standard is similar.

5. Protection objects: The protection objects are divided into KP and KN, KP is able to protect oily and non-oily particles, while KN is only able to protect non-oily particles

6, protection grade: China's protection grade is divided into KP100, KP95, KP90 and KN100, KN95, KN90. Among them, KP100 and KN100 have the highest filtration efficiency of more than 99.97% according to the national standard, so they have the highest safety for use.

Choose way

1. mask dustproof effect is good. The dust blocking efficiency of the mask is based on its blocking efficiency against fine dust, especially respirable dust under 5μm. The principle of dust prevention of gauze masks is mechanical filtration, that is, when dust and gauze collide, some large particles of dust will block layer by layer. But fine dust, especially dust less than 5μm, passes through the mesh of the gauze and enters the respiratory system. In the sales market, there are several filter materials containing permanent static electricity, the filter material is a fiber containing permanent static electricity, the respirable dust less than 5 microns through this filter material, is attracted by static electricity, adsorption on the filter material, really play a role in preventing dust.

2. mask and face shape close to the degree of good. Since the mask is not in close contact with the face, airborne dust will enter the airway through gaps around the mask. Therefore, people should choose the anti-particle mask in line with their own face shape, and wear dust masks appropriately.

3. wear comfortable, including small respiratory resistance, light weight, wearing health, convenient maintenance, such as wearing an arch anti-particulate mask.
