Review on Premium Quality PG Cabin Air Filter PC99350 for Mazda CX-9 2016-2021: Enhance Air Quality for a Cleaner & Healthier Ride by William Gildea

The filter was identical to the one I removed. See YouTube for removal/replacement instructions. The most time consuming thing was emptying the glove box as the filter is behind it. Guys I wasn't sure if I should replace this filter when I changed the engine air filter, after all living in North Carolina means driving with the windows open and the air conditioning on. But since the cost was much lower than at the dealer, I exchanged it. When I removed the old filter I was stunned at how much dirt it caught. Change this filter regularly, especially if you are prone to allergic reactions related to airborne spores.
