Is the smell of the mask harmful? 1 There are many reasons why masks smell. First of all, look at different types of masks. Among them, the common cause of odor in non-woven mask is the odor produced in the refining process when raw materials are copied; Bad merchants add materials to reduce costs, which leads to the odor of masks; Sour taste caused by process error in the production of non-woven activated carbon mask.
The cotton masks sold in the market in winter also have odor, mainly the odor caused by mildew and deterioration of cotton masks during storage and the odor left by printed masks during printing. Some of these smells are harmless to the human body, of course, there will be differences according to the sensitivity of individuals to smells.
Causes of odor in disposable masks.
Newly bought. Medical masks have odor, which may be the residual odor after ethylene oxide disinfection and sterilization. It is recommended to take it out for ventilation and eliminate the odor before wearing it. If it is not a medical mask but an ordinary disposable mask, there are many reasons why the mask smells. Among them, the common cause of odor in non-woven mask is the odor produced by raw materials in the refining process; Bad merchants add materials to reduce costs, which leads to the odor of masks; Sour taste caused by process error in the production of non-woven activated carbon mask.
Can disposable masks still be used if they smell?
Disposable medical protective masks can be used unless the masks have expired or have an odor. The main function of disposable medical protective mask is to isolate droplets or blood in the air, body fluids or other secretions in the air, and absorb dust. It is a very good tool to protect the health of doctors. Generally speaking, disposable medical masks must undergo strict testing and certain medical treatment and maintenance before they can be used.
Precautions for wearing a mask
1, and the wearing time should be appropriate: the medical protective mask can be used continuously for 6-8 hours, and should be replaced in time in the following situations: the respiratory impedance is obviously increased when the mask is damaged or contaminated (when breathing is difficult); Mask and face don't close; After contact with patients or carriers.
2. Air tightness test after wearing: Face air tightness test should be carried out when wearing disposable medical masks. The simple test method is to put on a disposable medical mask and exhale forcibly so that air cannot leak from the edge of the mask.
Do disposable masks taste normal?
3. Don't squeeze the mask by hand: All kinds of masks can only isolate the virus on the surface of the mask. If you squeeze the mask by hand, the virus will soak through the mask in droplets, increasing the chance of infection.
Is the smell of the mask harmful? There are several reasons why masks smell:
1. The raw material of non-woven fabric, polypropylene particles, has an odor.
2. The production process of non-woven fabrics is improper, and the non-woven fabrics have peculiar smell.
3. Improper storage and transportation of non-woven fabrics, limited factory environment, and peculiar smell in the space where semi-finished products are placed, leading to the adsorption of environmental peculiar smell.
4. Due to the limitation of production process, there is thermal oxidation of polypropylene and complete decomposition of polypropylene, resulting in peculiar smell.
Does the mask taste bad and do harm to the body?
According to the comprehensive product research, the main components of the odor on the mask are carbonyl compounds, formaldehyde, acetaldehyde, ketone, alcohol, acid, acetophenone and so on. These gases are collectively called VOCS, which are undoubtedly harmful to human body. Therefore, on the other hand, odor may be toxic.
Although the mask smells toxic, it depends on the specific situation whether the concentration of toxic gas components reaches the level that can endanger human health. If people can clearly feel that the smell in the mask makes them uncomfortable, disgusting and unacceptable, then it has certain toxicity.
If the smell is only slight, it will generally not cause any harm to the human body.
Preservation, cleaning and disinfection of masks
1. If you need to use the mask again, you can hang it in a clean, dry and ventilated place or put it in a clean and breathable paper bag. Masks should be stored separately to avoid contact with each other, and the users of masks should be marked;
2, medical standard protective masks can not be cleaned, nor can they be disinfected by disinfectants, heating and other methods;
3. Self-priming filter respirator (full face or half face) and power filter respirator should be cleaned according to the instructions;

If the odor occurs before wearing, it is generally caused by the mask itself, which has a certain relationship with the materials and production technology used in the production of the mask.
Does the mask taste bad and do harm to the body?
It depends.
Masks have many smells. If the mask quality is qualified, it is generally because the non-woven fabric it uses is produced in the process of producing and refining raw materials. This smell is generally harmless to the body, so don't worry too much.
There are also some masks that smell bad because some unscrupulous merchants use inferior raw materials in order to save costs, and the production technology is not enough. The mask produced can not only play a corresponding protective role, but also cause certain harm to human health.
Is it fake that the mask smells?
Non-woven fabrics for masks are mainly polypropylene spinning materials, in which polypropylene is polymerized from propylene, and various additives will be added in the production process, so it is normal that the mask itself will have a certain odor after production.
However, this smell is generally small and will volatilize after being blown away by the wind. Therefore, if the odor of the purchased mask is too heavy to bear, it is recommended not to continue wearing it, so as not to cause harm to health.
How to remove the odor of the mask?

If the used mask has an odor, the microorganisms on the mask can grow rapidly at a suitable temperature, because the human body will exhale protein, fat and water, which will cause the mask to stink. It is recommended to replace it in time.
