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.

Outstanding Performance, Minimal Installation Guidance Needed
I am delighted to award five stars to the cabin air filter with activated charcoal for my 2022 Chevrolet Tahoe Z71. Installation was a breeze, and it fits my vehicle perfectly. The activated charcoal feature is incredibly effective in eliminating odors and enhancing air quality within the cabin. While the absence of written instructions was a minor inconvenience, a quick reference to the item listing on Amazon provided the necessary guidance for installation. Once in place, the filter performed admirably, ensuring a clean and fresh interior environment. Overall, I wholeheartedly recommend this product to anyone seeking to upgrade their car’s air filtration system. Its exceptional performance and ease of installation make it a standout choice. Five stars without a doubt.
