Review on EPAuto CP671 CF11671: Cabin Air Filter Replacement with Activated Carbon for Mazda CX-7 / RAM 1500-5500 by Michael Copeland

Installed this filter on my truck during all of the wildfires here in California this summer. This filter actually significantly reduced the smell of smoke. The smoke in the Sacramento Valley region was so thick it resembled winter fog. I didn't know how well it worked until my wife and I took a three hour drive and found ourselves in the cab of my truck with the air conditioning on and the windows open. When we got out of the truck, the smell of smoke was terrible. This was a very good test of the effectiveness of this activated carbon and baking soda filter.
