The metal strip is on the top, and the part where the ear hooks on both sides of the mask are adhered to the surface of the mask is the inner side. Fit the mask to the face, press the metal strip with the index fingers of both hands to make it fit the bridge of the nose to prevent air leakage.

Can white medical masks prevent infection?

There are many types of masks, but their effectiveness has no direct relationship with the color of the mask. The most important thing is to look at the structure and function of the mask and the types and sizes of particles that can be filtered.

Disposable medical masks or ordinary disposable masks on the market can play a role of isolation. They can not only prevent droplets transmitted by foreigners during contact with people, but also reduce the amount and spray speed of their own droplets. They are good protection tools for both oneself and others.

Usually, masks are divided into three layers from the inside to the outside: water absorption layer, filter layer and waterproof layer, which filter the inhaled and exhaled air through different functions. When wearing, you should pay attention to the waterproof layer facing outwards, which is mostly a darker layer. Of course, many masks are white. Then put the metal strip on the bridge of the nose to fit the mask to the face according to the shape of the nose bridge to prevent air from entering the gap and being inhaled into the human body, ensuring that the mask fits tightly to the face and does not leak.

The difference between white masks and blue masks

Medical masks are not only available in blue, but also in white, black and pink.

Medical masks are generally used in hospitals, mainly for doctors and nurses. Blue can make people feel relaxed and not afraid. In addition, blue is more resistant to dirt and blends in with the environment of the operating room. White is rarely used in hospitals. It can stimulate the patient's vision and make the patient nervous.

There are many other colors of medical masks on the market, including black and pink. They are generally used by citizens to prevent inhalation of excessive particulate matter.
