What is FFP2 mask?

FFP2 masks refer to masks that meet the European (CEEN149:2001) standards. The European standards for protective masks are divided into three levels: FFP1, FFP2, and FFP3.


Testing equipment:

The detection of FFP2 masks, whether it is a European standard or an American standard, is designated to use the American TSI-8130 Automated Filter Testers instrument. The American standard uses the NaCl method for class N, the R class uses the DOP method, and the European standard uses the DOP method.


The TSI-8130 instrument uses the NaCl method: the instrument can automatically generate salt particles, the average diameter of the particles is 0.2μm (aggregate average diameter 0.26μm, arithmetic average diameter 0.07μm) after the sample is set to pass through the sample under a certain flow, the instrument automatically prints out Flow, resistance, transmittance.


In the DOP method, DOP oil is used to generate dust. The particle diameter of DOP oil is 0.33μm in aggregate average particle diameter and 0.20μm in count average diameter.

Usage:

1. Individual protection products designed to prevent or reduce the dust in the air from entering the human respiratory organs to protect life safety;


2. Material: Anti-particulate masks are mostly constructed with two layers of non-woven fabric inside and outside, with a filter cloth (melt blown cloth) in the middle layer;


3. Filtration principle: Filtering fine dust mainly depends on the filter cloth in the middle. Because the melt blown cloth has the characteristic of static electricity, it can absorb small particles. Since the fine dust is adsorbed on the original filter, and the original filter cannot be washed with static electricity, the self-priming filter anti-particulate respirator needs to be replaced regularly

4. Remarks: The international requirements for the use of anti-particulate masks are quite strict. The anti-particulate masks belong to the first level of personal protective equipment, which is higher than earmuffs and protective glasses. The more authoritative testing certifications include CE certification in Europe and NIOSH certification in the United States, while Chinas standards are similar to NIOSH in the United States


5. Protection objects: The protection objects are divided into KP and KN. The so-called KP is capable of protecting oily and non-oily particles, while KN is only capable of protecting non-oily particles.


6. Protection level: China's protection level is divided into KP100, KP95, KP90 and KN100, KN95, KN90. Among them, KP100 and KN100 have the highest national standard requirements for filtration efficiency greater than 99.97%, so the safety of use is also the highest.

Filter material:

Different FFP2 types of masks use different filter materials. On the one hand, the filtering effect is related to the particle size, and it is also affected by whether the particles contain oil. FFP2 masks are usually classified according to filtration efficiency and whether they are suitable for filtering oily particles. Oil-free particles such as dust, water-based mist, paint mist, oil-free fumes (welding fumes), microorganisms, etc. Although the filter materials of "non-oily particulate matter" are more common, they are not suitable for oily particulate matter, such as oil mist, oil fume, pitch fume, coke oven fume, etc. The filter material suitable for oily particles can also be used for non-oily particles.
