Fácil de instalar y se ve de buena calidad a comparación del que tenía en Valvoline por casi el mismo precio, compré este filtro para mi Civic 2017

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.
