That may be true. However, if you are a normal citizen (not a healthcare worker) and you have N95 masks, you should strongly consider donating them to healthcare providers right now
There are huge shortages of these masks in most US hospitals, even in areas with limited cases (cant speak for other coutnries but assume the same is true). HCPs are forced to either treat patients without wearing masks, guaranteeing high exposure to virus, or not care for patients
If you are sheltering in place (as you should be doing if you are healhty), N95 masks wont help you much. THey will 100% help HCPs
