How to choose your face mask

The mask mainly controls its pore size through its mesh design to filter the air that enters the body through the nostrils and oral cavity, and blocks the droplets, dust, and suspended particles from the outside air from entering the human body through the respiratory tract to achieve the effect of blocking bacteria, viruses and pollutants. There are different types of masks, and you can choose the mask that suits you best for different needs.

 

Common 4 masks

There are four types of masks commonly available in the market, namely surgical masks, cotton masks, N95 masks and paper masks. Among them, surgical masks are the most common and most commonly used, and are generally used for medical purposes to filter pathogens such as bacteria and viruses.

The medical surgical mask has three layers, the outer layer can prevent liquid splashing, the middle layer acts as a barrier to prevent germs, and the inner layer absorbs moisture and moisture released by the wearer. Due to its relatively high degree of tightness, large air permeability, and more comfortable,

After you choose the correct mask for your individual purpose, you must pay attention to how to wear it. Many people may wear the wrong mask all the time, and they do n’t know what to wear, which greatly reduces the effectiveness of the mask.

How to wear a mask? Keep in mind the following 8 key points:

  1. Wash your hands before and after wearing a mask

Many people pick up the masks and put them on. In fact, they must disinfect their hands before and after wearing them to prevent the hands from being infected with bacteria or viruses, contaminating the masks, or contaminating the virus outside the masks.

 

  1. Pay attention to the front and back of the mask

Masks are divided into front and back. The easiest way is to recognize the color of the mask. The colored side is facing outward. The other method is to recognize the metal wire. The metal wire should be facing up so that it will not be reversed.

 

  1. The mask needs to be opened

The mask is an organ design, and it should be pulled apart after wearing to completely cover the mouth, nose, and chin; don’t expose the nose when wearing the mask, otherwise it will lose the protection and antibacterial function.

 

  1. Press the metal strip tightly along the bridge of the nose

The metal strip of the mask has its function. It must be pressed tightly along the sides of the bridge of the nose to help close the mask, so as to avoid a gap between the face and the mask to prevent the virus from penetrating through the gap. This small action is definitely not too lazy.

 

  1. Mask rubber band hanging on the ear

The elastic band of the hanging ear mask is used correctly around the ears, even if you wear glasses, you don’t put it on the arm of the glasses.

 

  1. Masks are not reused

Remember to discard the mask after use. Do not use it once it is removed. For the best anti-virus effect, don’t be too “environmentally friendly”. The removed masks must be handled with care, and do not leave them in a place where others have access to them.

 

  1. Do not touch the outer part of the mask when removing it

The outward part of the mask may be contaminated with bacteria, so everyone should remember to avoid touching it as much as possible. Do n’t think that removing the mask is not important. In fact, when removing the mask, you should remove the elastic band of the mask from both ears. If it is a band-type surgical mask, you should first untie the band behind the neck, and then untie the band at the top. Prevent your hands from accidentally catching the virus.

 

  1. Masks should be discarded in a covered trash can

The correct way is to throw away immediately. The trash cans with masks should be covered. Wash your hands immediately after throwing away the masks.

 

Instructions for children with masks

In addition to the well-known N95 masks and surgical masks, there are many styles of children’s masks. Children’s masks with patterns will be easier to distinguish. Parents should ask their children to bring two new masks back to school. After lunch, do not put on old masks again and replace with new masks after meals. In addition, if parents do not know how to clean the mask, or do not have time to clean, it is recommended to use disposable masks, which will be relatively safe and convenient. Family doctor Mo Kunyang pointed out that in general, children aged 3 or above are suitable for wearing masks. Too young children have difficulty cooperating, basically wearing masks and playing a protective role. There is not much scientific basis for a body sticker that is put on the body to prevent bacterial infections.
