From what I recall from a prior article, this really is a bigger problem on Airbus planes than on Boeing planes, so much so that I will not fly on an Airbus plane. Until you vote with your wallet, no one will care.

Also, for multiple reasons, no one should fly without wearing a P95 or comparable or superior mask. You never know when smoke will hit. It is most critical during takeoff and landing, or if on the ground at a terminal. 3M 8577 is decent, with an essential bonus carbon layer. Place a disposable ASTM level 3 surgical mask on top too.

Note that an SpO2 finger meter can fail to recognize CO poisoning; it can be misleading with a false normal value of SpO2.

Uh.....what planes are you on where you, the passenger, can simply "pull down the oxygen mask"? Also, wouldn't the P95 only help with particulates (e.g. soot), but not with the actual toxic fumes?

OP has no idea what he's talking about. Passengers masks are for depressurisation events and oxygen supplies last 15 minutes - enough time for the pilots to descend. Pilots have a separate longer lasting oxygen supply. In many (most older?) planes, a single passenger activating their mask will activate the chemical based oxygen supply that feeds all passenger masks.

3M 8577 has a bonus carbon layer for this purpose. Its protection is not complete, but can limit the damage. You should also carry spares in case the carbon layer is exhausted.

How will you know that you should change mask?

		The mask itself starts to smell. You will start sneezing and also dripping from the nose, but this will stop if you remove or replace the mask. Also, you start to smell the diesel fumes. The more you wear a clean mask, the more sensitive your nose becomes to mild fumes.

Oh, very cool. TIL. Thanks!

I'd love to know what percentage of flights experience fume events to determine if it's a real problem I should worry about.

		100% outside of those with electric compressors for bleed air. You can smell it with your nose on takeoff and landing.

		For what it's worth, there is a very high number of harmful ultrafine particles in the air whenever a flight is taking off or landing, and also on the ground at the terminal. Most cases of exposure are just not acutely damaging to someone with normal lung function, but the damage absolutely accumulates with multiple flights. The heart in particular is no less sensitive to them than the lungs. The noted mask, if worn tightly, will block a good chunk of them.
