2007 Toyota Camry Q&A
2007 Toyota Camry Question: white dust from vents
I haven't seen this problem on newer Camrys. Is the new cabin air filter fully sealing in its housing? Was the old filter dirty with the same white dust? It would be interesting to pull out the "new" cabin air filter and check it to see how much debris and dust it has caught. - patrick mannion
Check out ford-white-dust.com. There is a technical bulletin that may have something similar to your other make vehicle. - tbpuppets
what is the white dust on my dashboard it seem to be coming through the air vents. I have replaced the cabin filter 3 times in 50k miles.
