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.
