Buy a mask and see the standard purchase according to the use.

 

 

Different standards correspond to different uses.

 

 

1. Medical surgical mask for droplet isolation (corresponding to the first-class protection of the hospital). When buying, please note that-look at the product name, it should be a medical surgical mask, second look at the outer packaging must be printed with the medical device registration certificate number, and third look at the outer packaging. The product implementation standards must comply with YY0469.

 

2. Medical protective mask for air isolation (corresponding to the secondary protection of the hospital). When buying, please note that when you look at the outer packaging, the medical device registration certificate number must be printed on it, and the second is that it must meet the GB19083 standard.

 

3. The basic requirements of GB19082 for medical protective masks are that they cannot have an exhalation valve, so masks with an exhalation valve do not need to be considered, do not buy it, and are not anti-virus.

 

4. The standard index of GB2626 is lower than that of GB19083. It is usually possible to prevent smog, so don't buy medical protection.

 

5. N95, which is usually said, is just a collective name, which represents the protection level. In fact, industrial protection and medical protection have N95 levels. Not all N95s are antivirus. Many businesses are now trying to fish in muddy water, blowing the N95 masks of industrial protection into antivirus, either stupid or bad.

 

 

 

In view of the confusion about the choice of masks, I am afraid that donating is wrong and will not be used. Here are some different standards for masks. The model and execution standard of the mask are printed on the left side of the mask. You can purchase masks according to this.

 

 

1. Masks are divided into three standards:

 

 

n95 is produced according to the American standard NOISH, the manufacturers are 3M and Honeywell;

 

FFP2 is the European standard EN149;

 

KN95 is the Chinese standard GB2626-2006.

 

All the three types of masks printed on the masks are qualified masks.

 

 

Second, medical n95 masks need to prevent high-pressure liquid splashes, so higher standards than ordinary n95; taking 3M as an example, models 1860 and 9132 are the most commonly used medical protective masks.

 

 

In addition, there are 1860s for children. Ordinary people or medical personnel who are not exposed to high-pressure liquid splashes can choose ordinary n95 masks that meet the NOISH standard.

 

 

3. European manufacturers of FFP2 standard masks include German UVEX, etc .; FFP3 is a higher level (99) protective mask.

 

 

4. Chinese standard GB2626-2006 refers to the standard of ordinary KN95 masks.

 

 

The standard of medical KN95 mask is GB19083-2010.

 

(Similarly, ordinary people and medical personnel who are not exposed to high-pressure liquid splashes can use ordinary KN95 masks, but there is a certain risk in an epidemic environment. The best batch number for medical equipment can be purchased. Reduce the risk of certain infections, but it is not recommended to try to walk around while wearing.)

 

 

5. Another common question is whether to choose a mask with or without a valve? Ordinary masks with valves are more comfortable.

 

 

Valves are not allowed for medical masks.

 

When ordinary people are infected or suspected of being infected, they must choose a medical mask without a valve (no one can find out whether the other party is infected or their own situation. It is not recommended to wear a mask with a valve in an epidemic environment).

 

 

6. Medical surgical masks, the common standard is YY0469-2010, or YY0469-2011, which is printed on the individual outer packaging of each mask.

 

 

Please stay tuned and buy individually packed surgical masks instead of 50 large packs. (Surgical masks are rarely individually packaged in the pharmacy channel. Commonly 10 packs, one can only wear 2- Change in 4 hours)
