The letters H-E-P-A represent the words High Efficiency Particulate air. HEPA filters capture almost all particles in the air that are zero point three microns in size or larger.
HEPA四个英文字母代表High Efficiency Particulate Air。高效微粒空气处理器能够捕捉到空气中几乎所有的微粒，即0.3毫米或者大一点的微粒。
On most commercial planes, at least half of the air comes from outside the aircraft and passes through a high-efficiency particulate air, or HEPA, filter which removes contaminants
在多数商用飞机上，至少有一半空气是来自于飞机外部，而且都经过了一种高效空气净化装置的过滤。
Inside your home, use a high-efficiency particulate air (HEPA) purifier capable of removing PM2.5 particles, or install such a filter in your heating system.
在你的家里，使用能够去除PM 2.5颗粒的高效颗粒空气净化器，或在你的加热系统中安装这样一个过滤器。
But studies have shown that high-efficiency particulate air (HEPA) filters on most jets today can capture 99.97% of bacterial and virus-carrying particles.
但研究表明，如今大部分飞机上的高效微粒空气过滤器能够滤掉99.97%的细菌和病毒微粒。
