Purchased this filter for my 2023 Outback. First off changing the cabin filter on this model Subaru is amazingly easy and can be done with no tools and no more then 5 minutes. Pictures posted show packaging, the paper "Blue" filter side, the "Black" charcoal side and the foam outer edge. The filter is well made and is very sturdy as the outer shell is plastic vs. other paper filters that are more flexible. Holding the filter in your hand and giving it a slite shake you can hear the activated charcoal within it. After installing the filter I had a few trips in the car, did I notice any difference in the air quality coming into the cabin....... no. But does this mean its not working? also no. What I can say is the filter fit snug and left no gaps, and with the plastic surroundings and foam in sure the filter will not be letting anything get by as it passes through the system. All and all this filter is well made and sturdy, and seems to be a good value with other paper only filters being about the same price.

Perfect Fit and Great Quality

Style: CF12552 Classic

The thickness is just right and fits perfectly. Easy to install, good airflow, and the air feels much cleaner after replacing the old filter. Great value for the price.

Easy to install

Style: CF10374 Classic

The frame is made of hard plastic (color black) which fits perfectly in the air cabin filter system of a Toyota Tacoma 2006 V6. It holds it's shap quite well. The carbon filter is able to be seen and works so far. The quality seems good and the thickness of the filter is well made with a foam outter film that makes it fit my Tacoma very well. I'm happy with it. The ease of installation is good and it is well worth the money.

Filter quality and value

Style: CF11809 Classic

2nd time to purchase this item over a 5 year period. The filter has a rigid frame making last much longer than other paper filters. Perfect fit and worth the cost. Great job filtering cabin and neutralizing odors!
