For those who wear N95s on planes, I can confirm that 3M Aura 9205+ works great with Vision Pro※ and doesn't hinder using it at all, nor reduce comfort, at least for my head and face shape.

※ - Tested during my 30 min demo (more like 45 mins) at the Apple Store.

Not criticism, genuinely curious: why? I thought cabin air was exceptionally well cycled and filtered, much more so than other indoor spaces.

I used to think this especially since airlines touted how good the air filtration was when COVID hit.

It's actually quite poor and significantly worse than most indoor spaces I've entered (most spaces aren't great at around 800-1600ppm). On planes I've measured※ very high CO2 levels (1800-4000ppm), with the worst air during boarding and deplaning. This matches the findings of others (both amateur and professional researchers).

※ - using Aranet4

I love how the recent availability of cheap PPM and CO2 sensors spawned a whole new subculture of air quality paranoia.

Based on Veritasium's recent video, given the cabins are pressurized by bleeding air off of the jet engine might not be too surprising about CO2 or particulates. However the cabin air is also exceptionally dry.
