found that dirty/soiled clothing was highly successful in filtering ozone from aircraft cabins. Next in line is the human body itself, through respiration then, aircraft interiors heavy chemical reactions between the seating material and ozone.


A little common sense while flight planning can go a long way. If possible, limit your time at the extreme altitudes/latitudes; Maintain proper pressurization levels per the operator manual; and, limit the use of body oils/moisturizers/hair products while in flight. This will go a long way in reducing cabin ozone levels.
