hello,
maybe i was exaggerating a little when i said "spewing dust". this is a new car with a black dash; and i notice every bit of dirt on it.
but it seems to get dust/lint frequently; i can't compare to the other car since i never noticed the dirt on that old junker.
i did buy a car air purifier, and when i take the car in for service, i will have them check the vents.
as far as the air purifiers go- i was wondering about the ozone and if it was safe. my mom's is O3- i don't know what that means, really- but i looked it up, and every website said it's supposed to be healthy for your lungs- but it doesn't sound like it.
i ended up buying one on amazon- forgot the brand, but it looked good- pretty sure it's a HEPA filtered one. it has a "silent" operation mode for nurseries or sleeping areas.
thanks for your help!
