Infographic on the chemistry oof air on a plane. Airliners pressurize onboard air to make flights more comfortable. In the cabin, the air pressure is 75.1 kPa, compared with 101 kPa at sea level. Cabin air is a mix of fresh and filtered air and is renewed up to 30 times an hour. Filters remove bacteria, fungi, and viruses. Airplanes cruise in the lower stratosphere, where the ozone concentration is slightly higher than at ground level. This increases cabin ozone levels, which can cause headaches and breathing problems. Many planes use devices to convert ozone in air into oxygen before it enters the cabin. A chemical system produces the oxygen provided by masks that drop from an airplane’s ceiling in an emergency. Pulling the mask down releases a firing pin from the oxygen generator cylinder. This release ignites a mixture of an oxidizer and iron powder. The heat from burning iron decomposes the oxidizer, a process that produces oxygen. The generator produces oxygen for 15–20 min.

I’m flying out to San Diego for #ACSSpring2025 today! Here’s a reminder of the chemistry that cleans the air you breathe on a plane in @cenmag.bsky.social: cen.acs.org/safety/consu...
