No idea . One thing that could affect this is how " Porous " the paper is ?
If I may add a little info that you may find interesting. Your engine "meters" the amount of gas based on the volume of air.
As your filter gets more clogged, it will compensate for the more restricted air flow volume by reducing the amount of gasoline.
Your car's computer is constantly maintaining the proper air/fuel ratio.
I used to think that as my air filter got more clogged over time that it would hurt my gas mileage. I have now been
taught that is not the case as my car's computer will simply reduce the amount of gasoline being injected into the cylinders.
It may hurt performance, I guess???
I may not be saying this in the technically correct way.
