This filter kit is a convenient all-in-one replacement for my 2011–2017 Honda Odyssey. Both the cabin and engine air filters fit perfectly and were easy to swap out in just a few minutes. The quality feels solid, and it’s great not having to buy the filters separately. A quick upgrade that helps the van run cleaner and keeps the cabin air fresh.

Impressive High-Tech Cabin Filter That Actually Eliminates Odors

This is by far the most advanced cabin filter I’ve ever used. My 2017 Civic came with a lingering interior smell that even a full professional detail couldn’t remove—but this filter did the trick almost immediately. The design is impressive, with a sturdy outer “shell” and clear labeling that makes installation quick and foolproof. It has a very modern, high-tech look, and the airflow direction is easy to identify. The fit is spot-on, and the performance has genuinely exceeded my expectations. I’m so impressed that I plan to switch my other vehicles over to this same style of filter in the future.

Size: HRV (2023-26) 2.0L Gas

These are exact fits for my honda 2025 Honda H-RV. It was super easy to install and took me less than 5 minutes to replace my old ones and put these in. Car smells clean and no debris in the intake! Seems to be good quality (been 1 week so far)
