At first I was confused why they'd market engine air filters as "fresh breeze", but see these are in-cabin filters. Gotcha.

Several years ago I put in a Fram engine air filter. Checked a few months later and it looked brand new.

Since I don't drive my car in a clean room environment, it was obvious that POS was not capturing anything.

I had already stopped using their oil filters. I wouldn't put Fram in my car if they were free.

GMTruckCentral test of air filter effectiveness against 5-micron aluminum spheres
The only seemingly valid air filter test I could find:  http://www.gmtruckcentral.com/articles/air-filter-study.html
The best filter blocked over 99% of the 5-micron particles sent into it, while the worst blocked only 60%.  The best filters were all dry paper or synthetic media (blocked 90-99% of particles), while the worst used oiled media, including the Fram TGA8038.  No dry media Fram filters were tested.  


I'd also be very wary of oil impregnated filters from anyone other than the original manufacturer. Oil can foul up the mass air sensor.
