Better than expected
I bought this thinking it was just like any other cabin air filter that fit my truck. It fits my truck perfectly. The Surprise was that it has a carbon filter side and is very well made. I can recommend this to you, and I will buy it again when it is time for a replacement.

Fit well
Seemed to fit in very well, was easy to install, and doesn't smell. I could see the charcoal beads on one side, which should help to pull out any contaminates; much better than the oem paper filters. Good value for the money.

Airflow
A very nice sturdy and colorful filter. The only drawback I have is I think the carbon medium is so thick that it does restricts the airflow a bit. I do notice the air is filtered better than my previous filter, which is why I am keeping it.
