Is it better to have water droplets on the mask or no water droplets?

In the process of wearing a mask, there will be various phenomena and problems. It is very common for masks to have water droplets, which happens to many people, especially in winter. So is it better to have water droplets on the mask or no water droplets? Let's take a closer look!

It is normal for the mask to have water droplets or not. Wearing a mask in winter usually has water droplets, which are caused by liquefaction. Generally speaking, the better the air tightness of the mask, the more water droplets will be produced. Relatively speaking, the defense effect may be better, but it needs to be replaced frequently, because water droplets will affect the use effect of the mask.

When wearing a mask in winter, there are often water droplets in the mask, because it is very cold in winter and the exhaled gas temperature is higher than the air temperature. When the hot air gets cold, it will liquefy to form small water droplets, and the outermost layer of the mask is waterproof, so when we wear the mask, the water vapor will be adsorbed inside the mask. For example, we can see white gas in winter, which is also caused by this.

In daily life, it is normal to have water droplets in the mask, because only medical masks can prevent diseases and viruses, and the sealing performance of medical masks is better. Long-term wear, the carbon dioxide exhaled by the human body can not be discharged, and water vapor will be generated.

But this is not to say that masks are not good. Medical masks also have certain air permeability, but the sealing performance is better than air permeability. On the contrary, such a mask will have a good anti-virus effect. You can wear it safely, don't worry too much.

How to look at the mask: check whether the face of the post is shiny and whether there is broken hair (broken hair, stains, yellowing and color cast are bad)

Feel 2: Feel whether the whole mask is soft, smooth and not rough (the fabric is hard, the light transmittance is large and thin, and the roughness is poor).

Three smells: smell the smell, from the cloth surface to the ear belt, smell it (if it smells, it is inferior)

Four Wear: Wear it to see if the ears, nose and face itch (if the ears thunder or itch, it is inferior)

How to wear a mask ① Choose a mask of appropriate size, and children can choose the size of children (children should use N95 mask as little as possible).

Wash your hands before wearing a mask.

(3) Wear a mask on your face. (The color face of the mask is outward, and the metal face is upward. If the mask has no color, the lower side of the fold should be outward)

4 If you choose a bandage mask, tie the bandage on the top of your head and behind your neck; If you choose earmuffs, wrap the rubber band of the mask around your ears so that the mask is close to your face.

⑤ Press the metal strips of the mask hard along both sides of the bridge of the nose to make the mask close to the face.

⑥ Open the mask and completely cover your mouth, nose and chin.
