Disposable Face Mask
Disposable masks also have a service life. Generally, the service life of disposable masks is 4-8 hours. If the respirator is polluted, deformed, damaged or has increased resistance, it should be replaced in time. It is mainly related to the concentration of external pollutants. The larger the dust outside, the dirtier the air, and the more things stick to the filter cotton, the faster. In this way, we have to be more diligent. If it is only used for commuting and the mask is kept clean, it can be used for many times. It is recommended that you do not use it after 8 hours, and replace it with a new one.

Although disposable masks are only used for one time, you must buy environment-friendly materials. For example, you can choose Yangpu disposable masks and Honeywell disposable masks. These two brands of disposable masks are better. When you buy disposable masks, you can choose the brand you like.

How long does it take to wear disposable masks?
