Are KN95 and N95 masks considered equivalent in Belgium and Italy?
I see references to FFP2 and to FFP2 Like masks, but I'm not finding anything that says they are legally interchangeable.
I'm assuming it's permissible to swap the masks mid-flight since we will be aloft for 13 hours and the masks aren't rated for that long, so I was planning to do the switch out about six hours into the flight.
This question is about the legality, being denied service or the right to board the flight. I'm assuming once I get into Italy, getting FFP2 will be super simple, but I have to get there first.
