Is the mask you wear really anti-epidemic?

Is the mask you wear really anti-epidemic? Can the printed and dyed masks on the market be worn with confidence? What should I pay attention to when selecting masks? To judge whether a mask has epidemic prevention function, the key point is to look at the code!
Only these five codes can really meet the epidemic prevention requirements:
Medical protective mask (GB19083-2010)
Medical surgical mask (YY0469-2011)
Disposable medical mask (YY/T 0969-2013)
Daily protective mask (GB/T 32610-2016)
Children's mask (GB/T 38880-2020)
The masks without the above codes do not meet the epidemic prevention standards
The state has also made clear provisions on the quality of dyeing and printing of civil masks: the color fastness of the inner and outer layers of masks shall not be lower than Level 3
