我觉得可以尝试。另外Medline也有出一款杀病毒口罩，用的是柠檬酸、铜和锌，作用类似。 “The Curad® BioMask™ works by using a combination of citric acid, zinc and copper — all powerful but safe ingredients. A hydrophilic coating on the outside quickly wicks droplets into and away from the outer surface. Viruses are inactivated on this outer layer by exposure to citric acid, which creates a low pH environment. The droplet then lands on the mask’s inner blue layer where influenza viruses are inactivated by copper and zinc, which are toxic to pathogens.” https://www.medline.com/jump/category-content/media-room/press-releases/2012/03/Medline-Introduces-Nations-First-US-Antiviral-Face-Mask-that-Inactivates-Flu-Viruses

有没有搞这个的来说说，是不是真的可行。
不过他们这个搞了3年多了，也没见有下文或者商品，能不能自己做一个。
比如我在口罩的外表面刷一层饱和盐水，或者其他什么浓盐水，等干了正常使用？
虽然盐粒结晶可能脱落，但是也能有一部分附着在表面吧？
毕竟在家，没办法搞成均匀的微粒覆盖啊。
