Just ask yourself, how this air contamination affected the entire crew of more than 20 stationed all around both decks of the A380 to the extent they need to attend hospital, yet did not affect a single passenger. When you've found a definitive answer to that question, you will probably know as much if not more than any aviation expert in the world.

The recurculation fan just keeps the air from seperating in the cabin so your head doesn't get hot while your feet get cold. Pretty simple.
As for some getting sick when they fly., Well don't lick your hands. Germs from sick people are everywhere and when they touch something the germs are there waiting for you to touch them. It is the cold and flu season... Wash your hands.
Hope it helps.

That's the case only as long as everything works as intended. I believe OP is interested in events where something harmful gets in the cabin air and causes symptoms to the pax and the crew, which isn't that rare at all:

And as a result you are more likely to develop asthma and allergies.
Seriously, a (modest) amount of regular contamination is good for your immune system. People should stop being OCD on cleanliness except where it matters.

The toxins in fume events are cumulative and build up in the body over time. When you have 20 people that fly a few times a week for say 50 weeks a year they are going to have higher exposure. That's why you see them get sick more often than the person who flies maybe a couple times a year. The average person just hasn't had the exposure to bring levels up high enough to feel sick right away. Hundreds of hours of exposure versus a dozen or so hours is the difference.

Is that a proven fact or just another theory ? Additionally, a full A380 crew would have experience ranging from 100's to many 1000's of flying hours, so rather strange to all meet the cumulative level to be affected simultaneously.

Great input. In addition, on most modern aircraft, the air passes through a HEPA filter before entering the cabin.

I have to agree 100%. The wiping of the stuff in the cockpit helps when I see the guy who left the plane was hacking and coughing but I mainly do it to get the food grease, slime, BBQ sauce and coffee smeared dirt off the controls. Pilots are pigs .........
Oink...

Having said that, coming into some airports you'll sometimes get a bit of a smell but since bleed air is just ambient air that has been temperature and pressure regulated, that smell comes from the same air you'll breathe after landing (sadly). So it's not the plane to blame.
Just to clarify, bleed air coming from the engines is taken from a location in the engines well ahead of any combustion, so all you get is air from outside.
Starlionblue wrote:On the ground, the APU inlet should get less crap than the engines. It is further up. But your results may vary.
I've sometimes caught a whiff just after engine start. Assuming this is because there's a bit of oil smell in the engines which is sucked in before there's proper flow, but not sure.
