Dust/Particulate is coming from passenger floor vents. Engine vitals are good. Is it the cabin air filter?

Changing the cabin air filter is fairly easy to do if you follow this how-to guide. New vehicles usually come equipped with one or more cabin air filters. A cabin air filter provides fresh air through the passenger compartment side vents. Step-By-Step Guide

1. The first thing you need to do is locate your owner's manual to find out if your vehicle is equipped with a cabin air filter. If you can't find the information, then your car is probably not equipped with a cabin air filter. However, if you would like to be sure, call your favorite parts store and they can provide you with the information.
2. When you purchase the new cabin air filter, be aware that there are 2 types of filters. One is called the particulate; the other is called the activated charcoal. The particulate filters out road dust, bacteria, mold spores, pollen and other pollutants. The activated charcoal filters the above mentioned and filters harmful gasses and odors. People who drive around in gridlock or have an odor problem might consider buying the activated charcoal, though it is more expensive.
3. After purchasing the filter, make sure you have your eye protection, gloves, ratchet, socket and screwdriver before beginning the procedure.
4. Remove the glove compartment. Usually, vehicles are equipped with bolts and screws to hold the glove compartment in. Your glove compartment may have tabs as well, so be careful when removing the compartment and use the tabs to remove.
5. After removing the bolt and the screws, remove the glove box frame.
6. Locate the filter housing. Look for a removable plastic filter cover.
7. Remove the filter. Most under-dash filters can be removed simply by opening the filter door.
8. Before installing the new filter, vacuum the filter chamber to remove any excess particles. You may also take a damp cloth and wipe the inside of the air filter chamber to clean out unwanted dust and particles.
