EN149 FFP2 dust face masks are the very best option to save people from COIVD-19 since their filtering effectiveness is very high (over 94%). This type of ffp2 face masks comply with the EN149 EU standard and based on their filtering performance, are classified as FFP1 protective mask (N95 in America and KN95 in China), FFP2 face mask (N99 in America and KN99 in China), and FFP3 mask (N100 in America and KN100 in China). For example, N95 means that the mask offers the intended effectiveness of filtering ninety-five percent of particles with a mass diameter of 0.3 micrometers.
But FFP2 NR face masks are disposable and their general use will make a bad impact on the atmosphere. The reason is that the material of the masks cannot be disinfected at 80 C for thirty minutes since it badly affects the mask filtering.
EN 149:2001 +A1:2009
The en149 dust mask according to EN 149:2001 +a1:2009 shows that they save against mist, dust, or fibers. The filters are tested to determine that they work rightly (filter penetration, also known as efficiency). Leakage around the edges, breathing resistance, and uptake capacity are also checked.
You will also find the FFP code on the dust mask box.
This European Standard specifies the lowest needs for filtering half masks used as respiratory protective gadgets, mainly against particles, and the needed laboratory and practical performance tests to assess masks’ compliance. Half masks used for escape objectives are excluded from the scope of this standard.
A filtering half mask is one in which the facepiece consists fully or substantially of filter stuff or comprises a facepiece in which the key filter form an inseparable part of the gadget.
Under the preceding EN149: 2001 +A1:2009 the classifications were FFP3S, FFP2SL, FFP1S, and FFP3SL. EN149:2001 +A1:2009 classified half masks into 3 types according to their filtering capacities (FFP3, FFP2, and FFP1).
The higher the number of en149 face mask, the better the protection. When you do a job that involves toxic substances, it is top to pick the highest protection.
A face mask with code FFP1 protects against big, powerful particles. Only perfect for protection against irritating, not bad substances. Lowest filter efficiency of 78 percent.
A face mask with code FFP2 or en149 mask ffp2 protects against liquid and powerful toxic aerosols. Minimum filter efficiency of ninety-two percent.
A face mask with code FFP3 saves against powerful and liquid toxic aerosols. Lowest filter efficiency of ninety-eight percent.
