Masks are indispensable daily necessities for people. With the deterioration of air quality, many people will wear masks when traveling. So there are some misunderstandings in the use of masks in daily life. So today's one-off masks will be a brief introduction to the general user's daily life. What should we pay attention to when using it in life?
If the air is too bad, it is suggested to consider shaving off the beard and wearing the mask, otherwise it will lead to air leakage and affect the filtering effect; if the face mask has begun to be contaminated, it is better to wash hands after wearing or removing it. Especially the N95 and above class masks - when you wear them, your hands are bound to touch the outside of the masks.
Don't share masks; especially, medical non-woven fabrics and activated carbon masks should not be worn back and forth - in the case of contaminated outside, they can quickly cause disease in the most serious cases; don't use head-mounted masks as ear-hanging.
We can't rely on only "N" and "KN" masks to deal with the pungent odor of decoration. For example, a simple "N95" mask can hardly filter the paint odor, because the volatilization of the paint will produce organic gases. At this time, it is best to choose particulate matter protective masks with activated carbon layer such as "KN90" 9042 (including activated carbon).
The air quality index is below 150. It is not recommended for healthy people to wear masks when they go out. When the index is below 50 (which is really rare in Beijing), it is recommended to ventilate the home vigorously; when wearing a mask to go out, you must be cautious when exercising with a significantly stronger intensity than fast walking. The greater the amount of exercise, the more obvious the resistance effect of the mask on breathing. So when the air is too bad, either try to reduce or avoid sports, or change to indoor sports. If you really need outdoor exercise, choose a cup-shaped, valved mask as far as possible.
