2007 Toyota Camry blows blizzard of white powder from A/C, is it health hazard? on 2007 Toyota Camry

My 2007 Toyota Camry A/C blows white powder from vents. It gets in drink sitting in cup holder and covers black blazer for important sales calls. It seems to make me itch and feel a little funny.
Is it a health hazard? If so, I plan to park it and contact an attorney.

Possible rodent chewed up your cabin filter and it's letting the debris blow through the vents.
