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

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.

Always fits and is easy to install
Size: 9.5" x 10.9" x 2.1"
We've bought these for years and they always fit and are easy to install. Easy to see when they are dirty and need to throw away. Embarrassed that we let the car dealership do it for so long. We set on six-month subscribe and save so that we know when to replace it - change it whenever it shows up!
