That’s actually not true at all. Bleed air from the engines is constantly pumped into the cabin to maintain pressurization, and what air is recirculated is pumped through HEPA filters. Airplane cabins on a properly maintained modern aircraft have surprisingly clean air.
I’ve heard that before too and I don’t doubt it. But being stuck in a plane for six hours with people smoking smelled worse than it does now. That would be the improvement part. Obviously they should have kept the air scrubbing anyway, but I’m guessing that would have cost them extra pennies, so they said fuck it.
