The Transportation Security Administration (TSA) and FAA do not prohibit the use of personal air purifiers on board airplanes and AirTamer^® is FCC certified not to interfere with airplane electronics. A very small number of airlines do restrict the use of personal air purifiers and it is always up to the discretion of airline crew on those airlines whether they follow the guidelines. Several airlines around the world actually offer AirTamer^® for sale in their inflight catalogs.
