Just what my vehicle's A/C, heat system needed ..
Good fit, and quality. Easy to change. You might be surprised how changing the cabin air filter can improve the airflow in your vehicles A/C, and heat system.

Perfect fit, Easy install, Better than taking it to a dealer.
This filter fits perfectly and easily. Unlike the dealer-installed filter (which I assume was an OEM filter but maybe not), it has arrows that indicate which side and orientation should be facing outward. The dealer-installed one does not have this and, as you can see from the photo, it was installed incorrectly. It should not be folded in on the sides. The old filter in the photo is after about 20K miles if that is a useful reference for you. Also, if you watch any YouTube videos, you will see a reference to releasing a plunger as the first step in releasing the glovebox door. For my 2018 Honda Accord Touring, there was no plunger, and that was confusing to me. If you don't see one, just go to the next step -- squeezing in the top, back corners of the glove box to fold it down. After that, everything goes like in the videos. Getting back to this filter -- it seems like it's better quality than the dealer-installed one. Shipping was fast. I would buy it again but, because this only takes a couple of minutes, next time I would do both the cabin and engine air filter at the same time so you might save a little money buying the combo set. Again, a very easy install and you don't risk having a dealer doing it incorrectly.

Perfect fit
This fit perfectly into my cabin air filter slot. Save me a lot of money, getting it off here as the mechanics went to charge so much more money just to slip this filter into your car. Anyone can do it so don’t hesitate to do your own cabin filter exchange and save yourself big bucks.
