N series is the American standard

KN series is the China standard

FFP series is the European standard

. The larger the number, the higher the protection level. If it is expressed by a formula, it will be easier to understand> FFP3FFP2 =N95= KN95> KN90

If the number ends with a V, it means there is a valve.

All the ones starting with 95 are the N95 series. The 90 series is not as high as the 95 series, but it can also resist more than 90%, which is much better than ordinary masks.

Under normal circumstances, the N95 series is sufficient to fight viruses and influenza.

In view of everyone's confusion about the choice of masks, here are several different standards for masks.

The mask model and execution standard are printed on the left side of the mask. You can buy a mask according to this

[1| Disposable masks are divided into three standards]

The N95 is produced according to the American standard NOISH, and the manufacturers are 3M and Honeywell

FFP2 are the European standard EN149

disposable masks

. All the implementation standards are printed on the disposable masks. All three are qualified masks

[2| Disposable masks and ordinary N96]

Disposable masks need to prevent high-pressure liquid splashing, so they have a higher standard than ordinary N95; taking 3M as an example, models 1860 and 9132 are commonly used disposable masks. In addition, there is a children's 1860s.

Ordinary people or medical staff who are not exposed to high-pressure liquid splashes can choose ordinary N95 masks that meet NOISH standards.

[Three| FFP2 and FFP3]

European manufacturers of FFP2 standard masks include Germany's UVEX and other

FFP3 is a higher-level (99) protective mask

[4| KN95]

Ordinary people and medical staff who are not exposed to high-pressure liquid splashes can use ordinary KN95 masks.

[Five| With or without a valve]

Ordinary masks with valves are more comfortable, but medical masks are not allowed to have valves.

When ordinary people are infected or suspected infected, they must choose a medical mask without a valve!

[Six| Disposable masks]

The common standard is YY0469 -2010 or Y0469 -2011

. It is printed on the independent outer packaging of each mask.

Model 1860/1870+ is used for medical operations, and

model 8210/8511 such as anti-dust is used for construction engineering.

Model 9210+ is used for industrial engineering. Two models such as dust control and rotten materials

that are widely purchased abroad (including the famous 3M brand) are both N95, but they are purely dust masks for construction, only preventing suspended particles/dust/pollen, etc. Not anti-virus at all! And it's expensive.

The N95 is a mask level. When purchasing, you must keep in mind the 1860/1870+ model, or it has the words antivirus, surgical, or flu-fighter, otherwise it will be useless.
