People seem to miss that better filters it is not just about higher price, but also higher CO2 emissions - filters decrease efficiency of the engine since they take energy to operate, moreover the energy consumption increases nonlinearly with decrease of particulates size. There's definitely a point where better filters don't make sense any more purelly from CO2 emissions perspective.
