Hello people, earlier in my Corolla I was using plastic mats over carpet mats and I had severe dust problem in my car. Every time I'd drive around the dust would always be getting in my AC vents and the amount of it floating around was remarkably high.
However, I realized that it was because of the fact that plastic mats does not hold the dust at all and every time you step on them, it makes the dust rise and float around. Since carpet has the ability to hold the dust, carpet mats are a much better choice if you're a person like me and doesn't want to see those little dust bits all over in your car. Surely it is not a great idea to protect the spills but still worth it.
