Find out all about air quality inside our airplanes

Having clean air inside the cabins of our airplanes has always been an essential requirement.

The air you breathe inside one of our airplanes meets very strict standards, is renewed every 3 minutes (more than 20 times an hour) and filtered through a highly efficient vertical recycling system. Air flows vertically, being propelled over the passengers’ heads and expelled under their feet, which forms a protective barrier between passengers seated in front of each other.

This system uses HEPA filters (High Efficiency Particulate Air), identical to those used in hospital operating rooms, and removes more than 99.9% of particles, viruses and bacteria, including the new coronavirus.

As a matter of curiosity, the HEPA filter blocks viruses and bacteria of up to 0.01 micrometers, with the coronavirus being 8 to 16 times larger, measuring 0.08 to 0.16 micrometers. The microorganisms retained by these filters are confined to a place whose humidity levels prevent their survival.

 

These filters effectively eliminate other types of particles that can harm passengers and crew such as dust, fungi and mites, ensuring that air is recycled and cooled in the same way and the same amount throughout the aircraft.

You can find out in more detail how the ventilation scheme works inside the aircraft in this video.
