In winter, when the incidence of respiratory diseases such as influenza is high, wearing a mask is not only an effective measure to protect yourself from being infected by others, but also an effective measure to protect people around you when you have respiratory symptoms, just like setting up a "filter barrier" for your respiratory system.

There are many kinds of masks on the market, such as fashion masks, ordinary medical masks and N95 masks. The unit price ranges from a few yuan to a hundred yuan, so how do we choose them in different situations?

1、 Disposable protective mask factory tutors you to choose the right mask

1. For people who are sensitive to cold air, such as those who love to snivel when they encounter cold air, it is appropriate to wear cotton gauze mask, because cotton gauze mask belongs to mechanical filtering mask. Relying on the layer by layer blocking of cotton gauze, it can only block particles with diameter as thick as hair. Although the filtering effect is poor, it has good thermal insulation effect and comfort.
2. When we travel by means of transportation, go to the hospital to see a doctor, or when our colleagues or classmates in the office catch a cold, it is more reliable to choose to use disposable medical masks at this time, because disposable medical masks have the function of anti splashing, and a large number of aerosol of respiratory patients will float in the air of the hospital. At this time, whether we are protecting ourselves or others, we should wear disposable medical masks They all fit.
3. During the period of high incidence of influenza, poor air quality and severe haze, we can choose protective masks. For example, N95 mask is a common protective mask, which has 95% filtering effect on particles with a diameter of 0.3 μ M. therefore, the protective mask is the best one to prevent haze. Although N95 mask is good, it is not recommended for pregnant women, the elderly, children or people with respiratory diseases to wear it, nor for healthy adults to wear it for a long time.
2、 Correct method of wearing disposable protective mask
1. Disposable masks can be divided into upper and lower parts. The one with nose clip is the upper part. After wearing the mask, pinch the nose clip tightly to make close contact with the skin. To prevent polluted air from entering the mouth and nose, the mask should be replaced every 4 hours.
2. Because the protective mask is to prevent the small particles that are all pervasive, it is necessary to ensure the perfect fit when wearing the protective mask. Among them, the headband type should ensure that the headband is separated from the upper and lower parts, the force is uniform, and the nose clip is pressed tightly. Then, take a deep breath by yourself, quickly blow and inhale a few times, and feel whether there is air leakage in your nose and mouth, so as to check the tightness. Only if there is no air leakage, can you really wear it well.
