Smog days are frequent, and masks have also become an indispensable tool for residents to travel. So do you know what kind of circumstances you need to wear a mask other than a haze? How much do you know about the correct way to wear a mask? We give you a few tips.
Before and after wearing the mask, you must clean your hands, and wear the mask according to the packaging instructions, including the tether that secures the mask so that the mask fits your face. If the mask is too loose and does not fit the face, air will enter through the side gap and preventive effects cannot be achieved. Disposable masks are not reusable. Gauze masks should never be used in reverse when they are in use. They must be cleaned after use and exposed to the sun to dry before reuse. If the mask is damaged or dirty, it should be replaced immediately. The mask should not be used continuously for more than four hours. When buying masks, pay attention to buying medical masks from regular pharmacies, and never buy and use non-medical masks that have not been strictly disinfected.
