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

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.
