People are so bad at statistics.
You know who else self-certifies their safety? Car companies. 30,000+ people die every year in car crashes in the US but that’s totally fine. (Of course I am well aware of various car company safety scandals where profit was placed above safety).
With US airline travel you have to go back multiple years before you find a single flight-related death on a mainstream commercial jet.
Meanwhile everyone I know seems to refuse public transit to the airport because of the “crackheads” and “homeless people” even though their car is way more dangerous than those supposed threats. I have to beg people I travel with to stop assuming that a taxi is going to be a better experience than a train or even a bus.
The fact that most Americans are against abolishing the 2nd amendment is also another piece of statistical ignorance. It’s such a no-brainer win on public safety but everyone is drunk on their revolutionary war propaganda from when guns didn’t even have the modern concept of bullets. You’re wildly more statistically likely to be shot by a police officer in the US than to be shot by an actual criminal in the UK because that’s how dumb enshrining the rights of killing appliances into a constitution is.
I’m all for the customer’s power to boycott, but the actual solution that will save lives is for the government and the FAA to tighten regulations and be more thorough.
For a plane type filter I’d personally use it more for comfort or perhaps CO2 emissions preferences and not safety.
