Air on airplanes is generally isolated to specific zones. In addition, most aircraft flying today pass recirculated air through a series of filters 20 to 30 times an hour. The filters used, called High-Efficiency Particulate Air, or HEPA, filters, are hospital-operating-room grade and capable of removing 99.9% of particulate such as bacteria, fungi, larger viruses and virus clumps, according to the Centers for Disease Control and Prevention.
飞机上各个区域的空气一般相互隔离 。此外 ， 当今的大多数飞机通过一系列过滤器每小时循环空气20到30次 。据美国疾病控制和预防中心说 ， 飞机使用的过滤器名为“高效微粒空气过滤器”（HEPA） ， 达到医院手术室级别 ， 能够清除99.9%的微粒 ， 比如细菌、真菌、较大的病毒和病毒团块 。
