Why You Should Keep The Air Flow Nozzle Open When On An Airplane

August 31, 2017

The air inside airplanes has an undue bad reputation, says a doctor who is an expert on the spread of infectious diseases associated with air travel.  While there is a lot of evidence that being cooped up inside a cylinder tube for hours with dozens of other people can lead to you catching a cold or flu, the air circulated in the airplane cabin isn't to blame.  The air flow on a plane works by compartmentalized it into sections of three to five rows.  Air is forced out through vents, either the main cabin vent or the vent above your seat.  Air exits the cabin through ducts below the windows, then mixed with fresh air from outside and filtered through a HEPA filter, which filters out most of the dust and microbes as it once again is circulated through the cabin.  So catching a cold through this method is limited.  In fact, experts recommend you leave the air flow above your head open and blowing down on your at all times.  The downward thrust of the air will do a pretty good job of protecting you from the coughed and sneezed germs flat around the cabin yet to be recirculated!
