δεν νομίζω.Το αεροπλάνο αποτελεί κλειστό χώρο όπου γίνεται βίαιη επανακυκλοφορία του αέρα χωρίς ανανέωση
σύμφωνα με τον κατασκευαστη:
Approximately 50 percent of the supply air is outside air and 50 percent is filtered recirculation air

και τα φίλτρα δεν συγκρατούν κυρίως τη σκόνη, αλλά:
The efficiency of HEPA filters to remove bacteria and viruses (.01 to .1 microns) is greater than 99 percent.
Airplanes take about 50 percent of the air collected in the outtake valves of the passenger compartment and mix it with fresh air from outside that gets heated by the engines..
