Disposable masks are reused, is it effective to spray masks with alcohol for disinfection?

I think try not to reuse disposable masks, in the process of disinfection, there is also a possibility of contamination with the virus, if there are no masks at home, try not to go out.

After the disposable mask is used for the first time, it can be simply wiped with alcohol with a cotton swab, but the mask that has been wiped with alcohol many times has poor airtightness and cannot play a good role in isolating germs.

It doesn't work, because spraying the mask with alcohol will make the mask very thinner and the protection will be greatly reduced.

I think disposable masks are famously disposable, so don't reuse them, because masks are relatively private, and then bacteria, what is more occupied? No matter how you disinfect with alcohol after that? The bacteria on it can't be removed, so it definitely won't work.

Spraying alcohol on the mask is not effective, spraying alcohol will destroy the sealing of the mask, which is equivalent to the entire mask being invalidated, so it is not recommended to disinfect the mask with alcohol.

No. Any kind of disinfection method will destroy the fibrous structure of the mask, make it deformed, and the filterability will be damaged, and the purpose of disease prevention will not be achieved. It is recommended to place disposable masks in a cool, dry and ventilated environment after use, and at the same time, they should be used exclusively for no more than 24 hours to prevent and reduce diseases.

Disposable masks cannot be disinfected with alcohol, and any disinfection method will destroy the fiber structure of the mask, making it deformed and filtered, and failing to achieve the purpose of disease prevention. It is recommended to place disposable masks in a cool, dry and ventilated environment after use, and at the same time, they should be used exclusively for no more than 24 hours to prevent and reduce diseases. If the disposable mask is obviously dirty, deformed, damaged, or has a peculiar smell, it is recommended to replace it in time to reduce the occurrence of diseases.

Masks cannot be reused after alcohol disinfection.

Because after the mask is sprayed with alcohol disinfection, it will greatly reduce the protective effect of the mask, and there is no original protection efficiency, which cannot play the role of blocking viruses and bacteria to protect us, so this method is not feasible.

Due to the special material of the mask, the outer layer is a splash-proof material, the innermost layer is a moisture-proof material, and the middle layer is also the core layer. Because when you inhale and exhale, some microorganisms or bacteria and viruses will be attached to it. Therefore, masks cannot be disinfected and reused, and the general use time is 4-6 hours.

In general, most of the masks we use are disposable masks, so the reason why disposable masks are disposable is mainly because of their non-reusability. If you forcibly wear a used mask, then there will be a certain danger.

Barrier principle of the mask:

1.Outer waterproof layer.

Usually needle-punched cotton is also called polyester needle-punched felt, polyester material itself is difficult to absorb water, and then polyester staple fiber is made into non-woven fabric by needle punching, it is difficult for polar water molecules and droplets to pass through, while non-polar air can be inhaled smoothly. In order to improve the effect of the waterproof layer, some masks are covered with fluorocarbon polymers, which further reduces the surface energy of the waterproof layer, thereby improving the waterproof effect.

2.Middle filter layer.

The main material of meltblown non-woven fabric is polypropylene, which is an ultra-fine and electrostatic fiber cloth that can capture droplets and dust. This layer of non-woven fabric is made of countless ultra-fine and electrostatic staple fibers, intertwined and hugged by mechanical force, and the droplets and dust are like walking in a maze in the jungle composed of staple fibers, and most of them stumble and adhere to the dense staple fibers under the action of electrostatic force and van der Waals force, thus playing a strong adsorption role.

3.Inner comfort layer.

It is a hot-rolled non-woven fabric, but the moisture absorption and air permeability are much better than the other two layers, mainly to ensure that the nose and mouth are moist and improve the comfort of wearing.

Disposable masks should not be disinfected with alcohol after use, mainly because the use of alcohol spraying may reduce the filtration function of the filter cloth. At present, due to the impact of the epidemic, disposable masks can be reused after ventilation disinfection and boiling water high-temperature disinfection, as long as the masks are not obviously dirty and deformed, they can still be used.

After the disposable mask is used, it can be placed in a ventilated place to dry, but it is best not to spray alcohol for disinfection. The inside of disposable masks generally has three layers of filter cloth and cotton cloth, and the use of alcohol spraying may reduce the filtration function of the filter cloth, so that the protective performance of disposable masks is reduced, so do not disinfect with alcohol.

After the disposable mask is used, it is logical that it needs to be discarded, but at present, due to the impact of the epidemic, mask resources are in short supply, so disposable masks can be disinfected and reused after making an exception. The best way to disinfect disposable masks is to fold them in half and place them in a ventilated place to dry, or put them in boiling water to steam.

Generally, disposable masks can be used for 4 to 6 hours, but due to the impact of the epidemic, as long as the mask is not obviously dirty and deformed, it can still be reused. If the mask comes into contact with contaminants such as sneezes, droplets, blood, etc., of a person with pneumonia, the mask must be replaced immediately and given to a professional for disposal.
