Is it possible to improve the air you breathe on an airplane? What about that little vent over your seat? Is it doing anything to help?
Most people realize that air travel increases the chance of catching a cold or some other respiratory infection. That’s because air circulation on airplanes leaves a lot to be desired.
Half the air you breathe is recycled within the cabin. The other half, however, is mixed with outside air. A High efficiency particulate air filter (HEPA) catches dust and germs.
Leave Your Vent On!
But you will be exposed to cold or flu viruses if someone coughs or sneezes in your general vicinity. That is why you want to keep the air vent on over your seat. A lot of people find that air too cold or annoying, but it is helpful in keeping germs out of your personal space.
The turbulence that air flow creates keeps your personal space cleaner and freer of viruses and other particles. A low or medium setting should be sufficient.
