How To Choose A Mask

Oct 28,2011

During the expansion of coronavirus infection, masks are a necessity when going out. Various types of masks are sold on the market, as well as masks printed with patterns and patterns, as well as masks emphasizing the effect of sunscreen. So, does this mask also have the effect of preventing infection? Also, how to choose a mask with good preventive effect?

 

What are masks that are not suitable for preventing new coronas?

 

The common types of masks on the market include sunscreen, cold protection, fashion, medical treatment, industry and so on. Among them, the anti sun, cold and fashion masks are not recommended for the prevention of new coronavirus infection. The reasons are as follows.

 

Cold mask

 

The sunscreen mask made of ice silk and the cold mask worn in autumn and winter have high transmittance and can not stop the virus.

 

Fashion mask

 

First of all, although this type of mask looks very similar to the serge camask for medical use, it can not completely block the virus, and some will invade through. In addition, this mask is often printed with oily color ink. If it is a mask that is easy to fade, the skin will be stimulated and may also cause allergic reaction. In addition, if the mask uses dyes containing carcinogenic aromatic amines, it may affect health.

 

What is a gas mask?

 

N95 masks, medical ronin masks and disposable medical masks that meet Chinese national standards have high anti-virus effect and are suitable for preventing new coronas.

 

N95 respirator

 

The medical N95 mask has the effect of blocking particles. In addition, it has a layer to prevent the invasion of liquid droplets. Especially when the doctor allows the patient to pass through the trachea, it can effectively prevent the invasion of virus.

 

However, the barrier effect of N95 series masks (n99, 95 and 90) is the strongest. However, due to poor ventilation, it will become difficult to breathe if worn for a long time. It is suitable for healthy people who need to move in scenes with high risk of infection.

 

In the market, some stores sell industrial dust masks as medical N95, so many people confuse the two kinds of masks. Please remember that the certification numbers of industrial dust masks are Kn90, kn95, kn100, kp90, kp95, kp100, etc.

 

Medical surge mask

 

Medical serge carmage also has a layer to prevent the invasion of filters and liquid droplets. However, compared with the medical N95 mask, the blocking effect of particles is slightly worse. If you are an ordinary person in a low-risk area, you can expect the surge mask for medical use to have sufficient preventive effect.

 

Disposable medical mask

 

This kind of mask is usually non-woven, which can prevent the secretion of nose and mouth from being polluted. The effect of virus block is worse than that of serge camesk for medical use.

 

Children's mask

 

When purchasing children's masks suitable for children's skin, respirator, head size and other characteristics, please choose the masks that meet the standards.

 

Selection method of masks suitable for new coronal Countermeasures


 

If it is difficult to select and identify the mask with high preventive effect of the new corona, it can be confirmed from the specification number displayed on the mask box and bag. The specifications and numbers of five masks suitable for the new corona are as follows.
