What are the standards of the face mask?
Firstly, let’s know the testing standards for the surgical mask.
The most popular standards now are the NIOSH and FFP standards.
N95 (United States NIOSH-42CFR84) filtration percentage: Not less than 95%
FFP2 (Europe EN 149-2001) filtration percentage: Not less than 94%
KN95 (China GB2626-2006) filtration percentage: Not less than 95%
Both N95 and KN95 rated mouth-muffle are effective at filtering out at least 95% of particles. FFP2 masks are rated at 94%. For this reason, N95 and KN95 masks are very slightly more effective than FFP2.
The most controversial is the N95 and KN 95 standards. In fact, it is just the different testing material, For FFP, the testing material is NOCL&DOP, but KN standard is NaCl. But it was in the spotlight after the affair of Netherlands recalls 600,000 face masks from China.
A disposable mask can stop the COVID-19?
The answer is yes, the disposable mask has industry and surgical two kinds.
Usually, the disposable mask has a three-layer, two-layer of non-woven fabrics and the most important is the middle melt-blown fabric. It can stop 99.99% of bacteria and dust. After the outbreak of the corona virus-19 in all over the world. The mask production machines, the raw material, the melt-blown fabric, even the earring belt, the express cost, the worker salary, all of them are times increased. Then cause the mask, no matter what kind of mask N95, KN95, FFP, even the cloth dust mask price explode.
Here, i don’t want to discuss the price of the mask, I am in China, I know how difficult to buy a mask during the most difficult time. Even though, china produces a 50% mask all over the world. Even though nearly all industries that have little relationship with mask switch to mask production. And China has been proved that wearing a mask is the easiest and cheap way to stop the spread of the COVID-19.
After all, the president of America Donald Trump also suggests people use the scarf to cover the nose and moth. If he doesn’t trust MADE IN CHINA so much, he should check whether his scarf is made in China or not.
Last, I suggest all the people keep heath and keep a cool head. Trust the science. COVID-19 can be prevented and control. We are common people, we can not change the country regime, but we can change our life habit. DO FROM NOW.
