When there are no medical masks in local pharmacies, Aliexpress becomes a good alternative to ensure a small supply. There are many types of masks. All of them are designed for different purposes: to protect against viruses, from dust and even just for beauty. We solved to choose the best quality of what the Chinese offer us and made this selection.
There is a description of the standard for making filters for the current type of medical mask. We propose you a small educational program for those, who doesn’t know the difference of masks.
FPP3 is a standard for protection against small particles of the technical and medical type. They are viruses, radioactive dust, asbestos, paint, mold spores, etc.it Provides up to 99% protection .
N95/KN95/FPP2 is the same as FPP3. But the degree of protection is about 92%. That’s why it is much easier to breathe while using the mask.
PM 2.5 is the protection against small particles of dust, soot, salts, heavy metals, gases and moisture droplets greater than 2.5 nm.
All of the above standards perfectly protect your respiratory system from getting viruses through coughing and sneezing of others.
