Singaporeans are snatching N95 face masks off the shelves. But what is N95? "95" in N95 means that the mask can filter at least 95% of air-borned particles.What about the "N" in N95? N stands for Non-Oil resistant. Do you know that there is O95 face mask and P95 face mask as well? There is also R95,R99, R100; P95,P99, P100 face masks as well (see reference)?
I feel like I am the condor hero when I wear the N95 face mask out. When one wants to buy N95 face mask, please ask for the brand. Those unscruplous can take a simple mask, writes "N95" and calls them N95 face masks as well and sell them.
