Can I still wear a disposable mask after its expiration date?
Disease description:
To prevent viruses, it is necessary to wear a mask. Would you like to know whether expired disposable masks can still be worn?

It is generally not recommended to use expired disposable masks. Specific reasons are as follows:
1. Reduced protective effectiveness: After expiration, the mask's protective capability significantly decreases, making it ineffective in blocking viruses, bacteria, and other harmful substances.
2. Potential contamination: During storage, expired masks may become contaminated due to environmental factors such as humidity and temperature changes, leading to bacterial or mold growth, which can pose health risks.
3. Material degradation: Over time, the mask's material gradually deteriorates, affecting its filtration efficiency and seal, thereby compromising effective protection.
