Gauze mask is a kind of daily mask, which is made of multi-layer cotton yarn, thick and comfortable, and can isolate dust, pollen and other large particles. Not a disposable mask, it can be reused after cleaning.
Can gauze masks isolate viruses?
I can't.
The fiber gap of ordinary gauze mask is more than 5 microns, and the virus particles are very small, mostly in nanometers, so gauze mask can not effectively isolate viruses or bacteria, or even block droplets and body fluids well; Moreover, gauze masks will absorb moisture in the air, which will increase the risk of infection.
How long can gauze masks be used?
Depending on the quality and type.
Generally, gauze masks need to be replaced after cleaning for 3 to 7 times. If the gauze mask is of particularly good quality, it can be cleaned 10 times and then replaced.
For gauze masks of activated carbon mask type, attention should be paid to replacing the activated carbon interlayer regularly; If the activated carbon interlayer in the mask cannot be replaced, it should be replaced after 7 to 14 days of use, and this gauze mask cannot be reused after cleaning.
