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

If you can pack it better. The box with the filter is thin, so it came in an envelope. The filter was a bit out of shape, but I got to work.

I was amazed that the filter wasn't damaged. It came from the manufacturer in a light cardboard package that wasn't even sealed with tape. Since it is basically a paper filter, it could easily be crushed or destroyed.

Filter fits perfectly on 2016 Mazda CX-9, instructions are included to replace the old filter although practically not necessary. The exchange took less than five minutes. An OEM quality filter should easily last a year. Made in China.

Meets expectations. I would have given 5 stars but one of the folds on the side was pleated/crumpled which allowed unfiltered air to pass through when installed. To solve this problem, I glued the crumpled edge to the filter frame so that the air filter was completely closed.

Fits perfectly in existing case, easy to swap out, no tools required (unless you can use a butter knife or something to pry case out, if fingers don't help I used my fingers), easy instructions to follow. Also a very good video online if needed.

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…
