KLM aircraft are equipped with High Efficiency Particulate Air (HEPA) filters, ensuring high-quality, clean cabin air that is regularly circulated. The air in the cabin is replaced every three minutes by the aircraft’s air-conditioning system, with airflows circulating top-down, thereby even further reducing the chance of “horizontal” transmission.
Furthermore, passengers all sit facing in the same direction, which means there is little face-to-face interaction, with seat backs forming a barrier that prevents forward and backward transmission in the cabin.
