Several months ago, I thought there might be some issue with my AC on my 2011,prius when i started to use it; the main vents didn’t seem to blow as hard as I remembered.
Just recently after having replaced my cabin air filter and engine air filter I noticed the cabin filter contained small bits of material like they use before laying carpet; never have I seen anything like that trapped in the cabin filter except small bits of leaves.
I also noticed prior to replacing the filters, that although i had the recirculation button on, i was still able to smell exhausts coming off of nasty cars; this has never happened whenever i choose to close the vents to recirculation.
Why would my cabin air filter contain these small bits of “soft felt” like material between the pleats?
Could there be something going on within the engine bay somewhere?
Like your two bits.
