What kind of mask is better

Generally speaking, masks that are breathable and can isolate pollution and bacteria are better masks. When purchasing masks, you can go to a pharmacy because the quality of masks there is more guaranteed. Disposable masks cannot be used multiple times and should be thrown away after one or two uses. Non-disposable masks should also be replaced after a period of time, rather than being used without replacement. Next, let’s take a look at how to choose a mask!

Methods/Steps

When choosing protective masks, some people's jobs require them to work outdoors temporarily, such as traffic police, cleaners, etc. You can use a cotton mask at ordinary times. If the air pollution is serious, you should wear a PM2.5 mask, such as an N95 mask. If you are only outdoors on your way to and from get off work, you should choose a KN90 mask to protect yourself from air pollution. It can capture about 90% of particles below PM2.5 without having much impact on your breathing.

The effects are also different. Medical protective masks are a type of tight-fitting, self-priming, filtering protective mask. There are many types of masks. It is used to prevent diseases and can play a role in preventing influenza A. Ordinary gauze masks are just a kind of health care product. They have a certain effect on filtering dust, microorganisms, etc. in the air, but the effect is average. Ordinary civilian masks are generally used for warmth and are made of different materials and specifications, so they cannot be used to prevent diseases. N95 masks are relatively high-performance masks that can isolate bacteria, filter viruses, and can be used to prevent air pollution. When choosing a mask, choose the type according to its purpose.

The higher the protection level, the higher the specifications of the mask. There will also be greater resistance to normal breathing. When choosing a mask, you should not only look at its specifications but also consider whether it is comfortable to wear. When used to prevent air pollution, KN90 masks are generally chosen, which can filter 90% of particles below PM2.5 and will not affect breathing too much. If a person has weak respiratory function, he or she should not wear a mask with too much resistance, as it may cause breathing difficulties and even affect the safety of life.

The above is how to choose a mask. If it is not a disposable mask, it must be cleaned and replaced frequently. It should be exposed to sunlight after each cleaning to reduce the growth of bacteria. If you feel difficulty breathing while using a mask, you should stop using it. This may be because the mask is too small, the air permeability is poor, the breathing space is too small, or there is a quality problem with the mask itself.
