How do you know it's passing thru your filter? Could be on your clothes,in the carpet or headliner. Is it more dust with this filter compared to the original filter?

I don't believe that there are,
yet, any MERV ratings for any
vehicle cabin air filters; but:

Use of a HEPA cabin air filter with a
filtration efficiency rating of 99.97%,
at 0.3 microns, will greatly reduce the
amount of cabin contaminates...espe-
cially when they're changed-out on a
regularly scheduled basis.


•Also:
-There may be some "dirty air" that's
sneaking into the cabin through the
window, trunk/hatch, and door Seals.

well, a thin layer of dust stick on windshield that I can wipe with my finger. I assume it is from air vents. All windows are closed. no air leaks.
