When I first put on the mask, I can always smell a strange smell, where does the smell come from?

It may be the smell of the mask itself, or it may be caused by bad breath, and you can smell the inside of your mouth by breathing after wearing a mask.

This smell is the smell on the outer layer of non-woven fabric, and in the process of production, the smell in the factory is also relatively large, and it is contaminated with this smell.

This smell comes from the mouth, so I don't think your mouth is hygienic.

It is very likely that there is a particularly strong chemical smell on this mask, and it is possible that you have bad breath because you have not brushed your teeth.

Many people will find that after the new mask is opened, there will be a bad smell, which is a very normal thing. It can be clearly found that most of the masks now use non-woven fabrics. If the non-woven fabric is made of polypropylene granules or other materials, then it will release an unpleasant taste, which is not toxic, but many people will feel very uncomfortable in the process of use.

There is also the reason for disinfectants, in order to meet the microbial standards of protective masks in China, many businesses will choose to use disinfection, and after the detoxification, they will be directly placed in the sealed bag, so everyone will find that it smells more unpleasant. <>

Cotton masks may become moldy and deteriorate during storage, so there is such an unpleasant smell, and in the case of medical masks, it may be because a substance called ethylene oxide is used to disinfect during the production process. Then, when you close it again, you will feel very unpleasant. If it is a mask produced by a regular business, then it is normal to have this unpleasant smell, and you don't need to worry, there are many medical masks that will also have such a smell.

If we are using a individually packaged mask, then before using the mask, we need to tear off the packaging bag of the mask, and then shake it in the air a few times, so that the unpleasant smell in the mask can be eliminated, and it can also make everyone safer and healthier when wearing the mask. In fact, there are very few harmful substances in masks, and there is no need to worry.

It is recommended that we should use medical masks, medical masks can better protect our safety, if we are in medium and high-risk areas, then, when we travel, it is best to wear two masks, so that we can more effectively protect our own safety. After the masks are used up, do not put them everywhere, and put a special trash bin at the door of the house to put the masks.

It may be that the new masks you bought are not very good, or some of the masks are disinfected with alcohol, but they are actually the residual smell after disinfection.

This is because the new mask is processed by a machine, and it is inevitable that there will be some smell of the machine, so it is more unpleasant, which is a normal phenomenon.

Because the new mask has been sealed and stored all the time, it has not been exposed to the air and the smell has not been released, so there will be a peculiar smell.

If the mask is worn for too long, the food and smell in the mouth will be attached to the mask, and the hand branches will be corrupt and smelly after a long time, in this case, it is not necessarily caused by bad breath, it may be used for too long, and there is a taste caused by microbial parasitism in the mouth, so it is okay to throw away the mask, so the general mask should not be worn for more than 4 hours, and it should be replaced in half a day.

If there is a smell not long after the mask is put on, it may be caused by the accumulation of the odor of Brother Bi in the mouth, because many times you may not be able to smell the bad breath in your mouth, but there are rotten bacteria in the mouth that may adhere to the mouth and the mask through the respiratory tract, and you will smell the smell of bad breath on the mask in a short time, so this is possible, and you should go to the hospital for tooth cleaning** and conduct an inspection of the dust pass.

In fact, the mask smells, because wearing a mask for a long time will make your breathing difficult, so you will smell a foul smell.

It should be bad breath. Many people will find themselves with this problem after wearing a mask, and you can go to the hospital for a check-up.

Depending on the type of bad breath, some people have poor hygiene habits, such as not brushing their teeth thoroughly, not liking to brush their tongue, bad teeth in their mouths, mouth ulcers, periodontitis, gum recession, etc., which may cause bad breath.
