How do airplanes get fresh air miles above Earth and how much of it is recycled
Aircraft cabins maintain a breathable environment by drawing air from engines, compressing and cooling it. This 'bleed air' is then regulated for pressure, ensuring passengers receive sufficient oxygen despite high altitudes. Advanced systems, including HEPA filters, continuously purify and recirculate air, creating a safe and comfortable atmosphere for all onboard.
