OK, it looks like BOSCH makes a particulate cabin air filter for our cars for $11.99 at Autozone. I ordered it in and it should be here within 24 hours. I'll post with more info then.
It looks like the cabin air filter was so clogged that it was sucking water and air in from the bottom of the cavity that the air intake sits in. Isn't there a drain or something in there? I couldn't see one...
