Review on AirTechnik CF10133 Replacement Corolla Martrix Replacement Parts by Dawson Schmidt

Fits perfectly on my Toyota Corolla. You will need a Phillips screwdriver for installation. It comes with fairly clear installation instructions, but they're missing one important point: the filter must be installed using the down arrow. It mentions that the arrow should point in the direction of airflow, just doesn't mention that the Toyota Corolla and Matrix for which it was designed points that direction downwards. Everything that has been said works well and takes 5 minutes to install. I doubt the antibacterial properties of this filter as most viruses and bacteria are less than 2.5 microns but I hope it will be effective against smoke particles during wildfire season.
