The air within an airplane cabin is recirculated every five or ten minutes. A real severe peanut allergy would be triggered by anyone on the plane eating peanuts.
It’s sort of is. But mostly they just mix it with a bit of outside air bumped up to pressure and release the difference, but it’s not really filtered, except in the sense that over time it will be filtered because the contaminated air will eventually all leave.
I’m sure they have filters like cars have filters but they’re not going to remove micro particles.

I would hope the air is filtered before recirculating.

That seems extremely stupid when airplanes are already major disease vectors, especially after covid.
Aircraft ironically actually had cleaner air back when they allowed smoking, because they then actually did have to filter the air.
That just sounds like utter bullshit mate
Air in a pressurised plane isn’t recirculated, it’s replaced with new air from outside.
It is recirculated and fresh air is mixed with it.
I assume they filter it in some way, but okay.
