Are they assuming that the filter only works in one direction?

Search for it ("does side of mask matter") and you will see all different ways to wear masks.

Colored side out, colored side in, or it doesn't matter because the filter works in either direction.

Some say the blue side is liquid proof.

Some masks are white on both sides.

Good Luck.

Just like underwear, turn it inside out the next day.
