The truth about air recirculation in airplanes

During the coronavirus pandemic, anything may seem suspicious and uncertain in terms of global health security. And if you plan to travel by plane, the questions about potential risks increase even more.

You ask yourself a lot of questions, to which you may not find the exact answer, such as how safe you will be at the airport and on the plane? What rules do you have to follow? Will you have access to the area you want to reach? How long before the flight do you have to be at the airport? One dilemma question before the coronavirus, which many are not sure how it works, is the recirculated air in the cockpit.

What’s the fear of air in planes?

Logically speaking, airplanes are pressure vessels, completely closed, that fly very high for several hours. Therefore, indoor air must be recirculated. If the same air floats around you and your peers several times, it would be loaded with germs and bacteria.

But this is not true. In fact, you don’t have to worry about air safety during a plane flight. Although it may seem surprising, there is fresh air in the cabin of an airplane, because they are not hermetically sealed environments. Basically, during a flight, fresh air from outside the aircraft is continuously circulated in the cabin through complex engine vents.

Air recirculation means that hepa filters are used that filter the air and eliminate up to 99% of bacteria and germs with high efficiency, filtering it every few minutes. Therefore, the air in the plane, say specialists, is cleaner than in crowded spaces, malls or office spaces.

However, not all planes have hepa filters, only the latest models. Of course, like most places, airplanes will never be 100% safe, especially in terms of social distance. Therefore, during the pandemic it is recommended to travel only if there are emergencies.
