Maintained airflow
Difficult to know how well it’s filtering the air. But it installed correctly and I am still getting good airflow through my vents

High-Quality Cabin Filter with Carbon Pre-Filter
This filter was easy to install in a 2010 Honda Fit. I wanted a HEPA filter given my severe allergies. The honeycomb carbon side looks similar to my Winix and Air Doctor carbon filters so it felt high quality.

Good alternative without
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.
