当前，疫情防控形势依然严峻复杂。要时刻注意个人防护，佩戴口罩，保持安全社交距离。现在市场上有很多种口罩。哪些口罩可以有效预防流行病？
选择口罩，并记得查看实施标准
药店和互联网上出售的口罩名称“各种奇怪”。普通消费者看不出区别。然而，只有以下五种代码才能真正满足防疫要求。
需要注意的是，根据《国家日常防护口罩技术规范》，非医用一次性防护口罩主要防护空气污染，而不是病毒和其他病原体。此外，一些口罩虽然也有执行标准，但属于企业内部标准，如q/fK01-2017，这使得此类口罩的防护能力难以保证。
而那些有着美丽图案的面具，只要你弄清楚它们采用了什么样的实施标准，就可以判断出来。你不能买不合格的漂亮的。
综上所述，防护效果从强到弱依次为：医疗卫生标准（YY）>国家标准（GB）>企业内部标准。
国家还对民用口罩的染色和印刷相关质量做出了明确规定，要求口罩内外层的色牢度不得低于三级，以防止染料脱落对面部和皮肤造成不适。染色和印刷部件应不含可分解的致癌芳香胺染料。
让我们来看看如何正确去除口罩
