Yes, totally agree to your point. The job of the high performance filter is to allow more air, which in turn allows some dust particles too. But the real question is? Is the Air to Dust ratio worth the money and the actual usage.
stock: allows 50% air and 5% dust
Product X: allows 70% air and 10% dust
Product Y: allows 90% air and 40% dust
The dust ratio is less in the product X. So this is the actual performance measure of a filter.
But as u said , product Y is only for racing not for day to day usage.
, but we can consider using product X if we are ready to change the filter little earlier than normal.
Experts shed some more light on this !
