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.
- klabb3 2y agoNot criticism, genuinely curious: why? I thought cabin air was exceptionally well cycled and filtered, much more so than other indoor spaces.
- isodev 2y agoAt the very least so one doesn’t sneeze over the person on the next seat.

- jonpurdy 2y agoI 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
- Dylan16807 2y agoAre CO2 levels a useful way to measure filtration? Are we expecting almost all the clean air to be from outside, minimal amounts from recirculation?
- jonpurdy 2y agoApologies, I specified "filtration" but meant "quality", which I would define as filtration + fresh air intake. I'd have expected a better mix (more fresh air) since even with filtration removing many particulates and viruses, high CO2 levels still cause worse cognitive performance.
- Dylan16807 2y agoIt's hard to get lots of fresh air into a pressurized plane, so I'm willing to have a good bit of leeway on that front. And airflow patterns are important; a lot of fresh air running from front to back would likely do more harm than good.
- criddell 2y agoHow does an N95 help with CO2 levels?
- macintux 2y agoI would wager it's not a matter of helping filter out CO2, but rather CO2 is one way to assess how effective the air management is on a plane.
- foobarian 2y agoI 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.
- jeffbee 2y agoAirplane air is clean but there are just too many people aboard and for too long. Something like a quarter of all air travel passengers get a respiratory illness within a week. Some hypothesize that the incredibly low humidity of cabin air (in most aircraft, except the very newest) makes it easier to acquire infections. A face mask, in addition to its normal role, also solves this problem because it is very humid inside the mask.
- sbrother 2y agoI don't know, but I always tended to get sick after flying. I started wearing a mask while flying during COVID and it's the one place I still do it. Not scientific but I feel like I have gotten sick after flying less frequently since then. It could even just be the effect of making myself breathe humid air in what's normally an extremely dry environment.
- AnarchismIsCool 2y agoThere are long periods where the filters aren't running during startup and shutdown, you'll notice once the seatbelt sign turns on at the beginning and right after it turns off at the end, things get stale super quickly and the temps start rising. That's because they turned off/haven't switched to air supplied by the jetway yet.
- newaccount74 2y agoA few family members caught covid on a plane despite everyone needing a negative covid test before departure and wearing a FFP2 mask during the whole flight. Put a lot of people in close proximity for a long time and it's going to be very hard to prevent transmission of airborne viruses...
- RJIb8RBYxzAMX9u 2y agoSlightly OT but I much prefer the 9211+: the vent[*] makes a difference in comfort when worn over long periods. Or the 9105 / 9105S which sticks out further away from the face, and its elastic design makes it a bit quicker to don / doff at checkpoints. [*] Yes I'm prioritizing my comfort over safety for others, but that's the American Way (tm), isn't it.
- JoshTriplett 2y agoThere are masks with full N95 filtration that have a fan built in to pull the air through the filter. Makes it much more comfortable to wear for long periods. (I switch to a mask with no metal in it for airport metal detectors, but I can switch back again immediately afterwards.)
- iyn 2y agoAny recommendations for such masks?
- JoshTriplett 2y agoThe Philips "Fresh Air" or "Fresh Breeze" mask (different names in different regions).
- jonpurdy 2y agoThanks for this recommendation; I was considering ordering these for my next trip since they should fit the same as 9205+. (I don't see an issue with wearing an exhalation vent next to folks who aren't wearing masks themselves. If they cared about the air they'd also be wearing a mask. If I sat next to someone wearing one I'd switch back to the 9205+.)
- btbuildem 2y agoI really wish they were made in not-stark-white. And, is it just me, or have these steadily been going up in price?
