Arrow is AIRFLOW direction, not UP direction. So installation direction might mean arrow of your Purolator filter should be down (true for glove box installs) even if arrow on old filter is up (if it was an UP indication). I wish they mentioned this in product listing, on box, or on side of filter like most brands. Luckily, telephone customer service was super responsive. Otherwise, product is correct size, appears sturdily made.

Perfect fit for my 2018 Civic—easy, affordable, and worth it

Size: 9.5" x 10.9" x 2.1"

I’ve bought this cabin air filter multiple times for my 2018 Honda Civic, and it’s consistently great quality. It fits perfectly and is super easy to install—takes just a few minutes to swap out, and I always do it myself. Way cheaper than going to a shop or dealership. The airflow is smooth, there’s no smell at all, and it keeps the inside of my car feeling clean and fresh. No weird odors, no dust blowing in—just a solid, dependable filter that does its job well. This is the only one I’ll keep buying.

Do it mayne

Size: 9.5" x 10.9" x 2.1"

Good quality and fit but find it funny that the instructions with the air flow are on the side. I assume that would be facing out and was annoyed when I tried to close and it didn’t fit. Probably should have read the directions. Still would recommend

Ordered this for our 2023 Honda civic. Great fit, durable and very affordable. Was so easy to pull old one out and replace new one. Will be ordering again.

Save money by installing yourself

Size: 9.5" x 10.9" x 2.1"

Good price and easy to install in a 2019 Honda CRV. Instructions can be found on YouTube. Much less expensive than having a service center install them.
