Installing air filters is an intervention that has a cost and thus needs to be verified and proven. You don't roll such a thing out on a broad scale based on "the effect could be large".

I find it bonkers we have better regulation around growing battery chickens than growing kids.

You don’t need massive study to find out that kids don’t like suffocating in classrooms.

It’s a bit like mandating reversing cameras on cars. Study says economically they do not make sense, but not squishing your kids trumps that.
