Nowadays, there are many kinds of masks on the market. I believe we will all have different feelings when wearing masks. For masks worn on the nose and mouth, it should be obvious to the sense of smell, so many people will have this question: Why do some masks have peculiar smell? Are these smelly masks harmful to the human body? Kaiyi Technology will now give you an answer

There are many reasons for the peculiar smell of masks, and we cannot generalize them. First of all, we have to look at the difference between different types of masks. For example, the non-medical non-medical non-woven fabric masks we often use are caused by the peculiar smell generated by the raw material copy during the refining process; bad businesses cut corners and materials in order to reduce the cost of making masks; non-woven activated carbon The sour smell caused by the wrong process of the mask in the production process. Some of these odors are harmless to the human body, and individuals have different sensitivity to odors.

The smell of the newly bought disposable medical protective mask is probably because it is the residual smell after ethylene oxide disinfection and sterilization. We can take it out to ventilate and eliminate the smell before wearing it. If it is not a disposable medical protective mask but an ordinary disposable mask, there are many reasons for the odor of the mask. For example, the non-medical non-medical odor of the non-woven daily masks we often use is caused by the copy of the raw materials during the refining process. The peculiar smell of the mask; the peculiar smell of the mask caused by cutting corners and materials in order to reduce the cost of making masks by the bad business; the sour smell caused by the process of the non-woven activated carbon mask in the production process. Some of these odors are harmless to the human body, and individuals have different sensitivity to odors.

If the mask is not expired or if it is a fake mask, it can be used. The main function of disposable medical protective masks is to isolate droplets or blood in the air, and also to isolate body fluids or body fluids in the air. Other secretions can also absorb dust, which is a very good tool to protect the health of doctors. Generally speaking, disposable medical masks have to go through rigorous testing and undergo certain medical treatment and maintenance before they can be used.

Points to note:

1. The wearing time should be appropriate: disposable medical protective masks can be used continuously for 6-8 hours, and should be replaced in time when the following conditions are encountered: the respiratory impedance increases significantly (when breathing is difficult) when the mask is damaged or contaminated; the mask cannot be closely attached to the face ; After contact with patients or pathogen carriers.

2. Perform a tightness test after wearing: Wear a disposable medical protective mask and perform a facial tightness test. The simple test method is to wear a disposable medical mask and exhale forcefully. The air cannot leak from the edge of the mask.

3. Don't squeeze the mask with your hands: all kinds of masks can only isolate the virus on the surface of the mask. If you squeeze the mask with your hands, the virus will wet the mask with the droplets, which will increase the chance of infection.
