Yeah, I tried ordering some bio masks a week after this started and no luck.
I have 20-40 N95 but from what I have read (and not here on FR, exact opposite) the N95 is not as efficient as the bio masks in trapping viral.
I believe this because if they were, hospitals would be using N95s instead of bios.
This is important to me right now because I am going thru lyme disease treatment and my immune system is effed up bigly.
Corona with lyme. Don't do that!

Watch out for inferior knock offs.
