2023 RAV4 Hybrid
The product is great and is OEM+ in quality. This has to be the easiest cabin air filter I have ever changed. The replacement is super simple. Take off the glove box by pressing in (check for Youtube videos), remove and take the plastic tray out, remove the old filter, and install the new one into the plastic tray, making note to match the direction of the arrows. Reinstall and you are done. Replace once a year.
