Maybe people will finally stop peddling those fabric masks.

If your mask doesn't have a layer of non-woven polypropylene, you might as well not wear a mask.

Look the difference below. That's right, that box of blue masks selling for $7.99 at the supermarket will outperform your fabric mask, regardless of whether it's made by Adidas or LV.

Go ASTM level 2 or 3 and you'll be fine.

Need CBC to clarify blue surgical vs non medical blue masks sold at supermarkets. They tested surgical masks per their article not the cheap non medical blue masks.

they are definitely testing regular procedure masks, which are at minimal ASTM level1.

Although many non-medical masks are equivalent or close to ASTM level1 procedure masks, it is still optimal to pay a few more bucks for a sounded brand.

For example, EU standards like EN 14683 are pretty much equivalent to ASTM level 1 per Health Canada.

The non-medical masks have a layer of non-woven polypropylene. That's what counts.

That's a waste of money unless you're expecting direct splashes.

This thing is airborne. Having a splash proof barrier is no good if there's leakage at the top and sides.

The logical upgrade from the standard blue masks is earloop KN95, followed by headband N95.

Sunday night I watched the American Music Awards and saw that lots of the performers, dancers and people in the audience were wearing masks combined with physical distancing. My observation in the 3 hours broadcast was that I don't remember seeing one single person wearing a generic blue disposable mask. LOL What's become very popular right now are the black disposable masks with polypropylene which most of the people were wearing.

I'm not sure they stated they didn't do anything. At that time PE was so scarce that there wasn't even enough for healthcare workers and the US stopped mask shipments from entering Canada. Even in hindsight it seems like an appropriate step was taken in order to discourage members of the general public against hoarding masks. Now that more is known about the virus and how it is spread it doesn't seem unreasonable to wear any type of mask available as any barrier seems to be better than nothing. It does make sense that certain types of masks would have better filtration capacity too.
