And today of course, that's of even greater concern.

當然現在這一點更令人擔憂。

But this is what I've just learned.

但是我剛剛知道一件事。

On this Emirates Boeing 777, and across their entire fleet, the air is constantly changed with fresh air from outside.

在這架阿聯酋航空波音 777 及其整個機隊中，空氣是不斷地跟外面新鮮的空氣交替。

For anyone who's actually interested, the air comes into the plane through the engines.

如果你想知道的話，空氣都是通過引擎進入飛機的。

This fresh air is mixed 50-50 with the air inside the plane, and is pumped back at the right temperature into the cabin.

這些新鮮空氣與飛機內部的空氣一半一半混合，並以適當的溫度被抽送回機艙裡。

The old air is released outside.

舊的空氣會被釋放到外面。

Now this new air, which is changed every 2 to 3 minutes, flows from the ceiling to the floor like this, and not through the plane like a lot of people think.

至於新的空氣每兩到三分鐘會透過天花板流進來，像這樣，並不是像很多人以為的那樣透過飛機流進來。

But this is the best bit.

但接下來最棒的地方。

The air in the cabin go through what they call HEPA filters, and these are about here.

機艙中的空氣都會通過所謂的 HEPA 過濾器，它們大概在這裡。

And these are able to catch 99.9% of viruses, bacteria, fungi, dust and germs.

它們能夠捕獲 99.9％ 的病毒、細菌、真菌、灰塵和細菌。

So, when you get the filtered air mixed with the new air from outside, it's actually cleaner than the air in your office or even a hospital theater.

因此，當你將過濾後的空氣與外面的新空氣混合在一起時，它其實比辦公室甚至醫院手術室中的空氣更乾淨。

Remember that time when you thought you caught a cold when you flew?

還記得你以為因為搭飛機所以感冒的時候嗎？

Well, it's likely that you got it elsewhere.

其實很有可能是你在別的地方被傳染了。

Like you, I want to see my family and I want to see the world again.

跟你一樣，我也想跟家人見面還有再去看看世界。

So, Fly Emirates, Fly Better.

所以，搭阿聯酋、飛向卓越。
