Komt de lucht in de cinema van een halve meter boven u, gaat naar onder, en wordt net onder u terug afgezogen, waarna die gefilterd wordt met HEPA filters?
"Thanks to HEPA filters and efficient circulation on commercial aircrafts,
the air you breathe in flight is much cleaner than the air in restaurants, bars, stores, or your best friend’s living room."
"On HEPA-equipped planes, the airflow mirrors the laminar airflow of an operating room
with no or minimal crossover of air streams. Air is pumped from the ceiling into the cabin at a speed of about a yard per second and sucked out again below the window seats.”
"About 40 percent of a cabin’s air gets filtered through this HEPA system; the remaining 60 percent is fresh and piped in from outside the plane.
Cabin air is completely changed every three minutes, on average, while the aircraft is cruising."
“Typically the number of particles in the air are really low,
the plane is almost a clean room, because there’s so much ventilation.
Planes are actually safer than virtually any other confined space.”
