Is the black mask a medical mask? How to distinguish the front and back of the black mask?

Are black masks medical masks? Generally, medical surgical masks have models. When you buy a mask, you must look at the model number carefully before purchasing. Most of the black disposable masks on the market are ordinary masks, which have no preventive effect on COVID-19. So, how do you distinguish the front and back of a black mask? Let's take a look!

Is the black mask a medical mask?

Judging from the quality, it must have three layers, and the middle layer must be meltblown cloth. Simply put, it is waterproof, and only in this way can it have a protective effect.

So the black mask you mentioned has several layers. If it has only one layer, it is obviously an ordinary mask. If it has four or three layers, it is a medical mask and it plays a protective role.

There are three types of medical masks used in the medical and pharmaceutical hospital fields, and their corresponding names are: disposable medical masks, medical surgical masks, and medical protective masks. The corresponding standards are: YY/T0969-2013 Disposable Medical Masks, YY 0469-2011 Medical Surgical Masks, and GB19083-2010 Technical Requirements for Medical Protective Masks.

Through the above comparison, you will find: medical protective masks > medical surgical masks > disposable medical masks.

How to distinguish the front and back of a black mask

Refer to the appearance of a Venetian blind to distinguish the front and back of the mask. The blind faces outward with leaves facing downward, shielding against the sun and rain. The mask is the same, with the outer side folded downward, so pick up the mask with the side with the pressure strap on top, then look at the fold, the side facing downward is the front.

How to wear a black mask

1. Whether it is a disposable mask or a medical mask, there is actually a front and back side. Take the disposable mask as an example. The darker color is the front side, which should face outwards. There is also a metal strip for the nose clip on the medical mask (the metal strip should face upwards when worn);

2. The back of the medical mask should be facing your face, which is the lighter side. In addition, please note that the part with the metal strip should be on the top of the mask. Do not wear it upside down.

3. After distinguishing the front, back, top and bottom of the mask, wash your hands first. After making sure that the mask is correct, hang the ropes at both ends on your ears.

4. The last step, which is also the most important step, is the metal strip problem mentioned earlier. After putting on the mask, you need to use both hands to press the metal strips on both sides of the bridge of the nose so that the upper end of the mask is close to the bridge of the nose, and then stretch the mask downward so that there are no wrinkles on the mask. It is best to cover the nose and mouth. In this way, the effect of the medical mask will be better.
