Well-Made Carbon Cabin FIlter
I love the honeycomb carbon filter on this cabin filter. It looks like it will do an excellent job cleaning the air in my car. It came in a cardboard box and was easy to install and fit my Toyota well. I would have appreciated some arrows on it, like other filters come with, to let me know I was inserting it correctly. I just followed the example of the one already in my car. If you accidentally take that one out first, you may not remember which side goes where. So, my improvement would be arrows on the filter itself. Otherwise, the airflow seems great, it functions well and seems to be a great quality!

Use activated carbon to clean the air naturally!
This is a serious air filter with activated carbon inside of it and I'm here for it. I use little activated carbon bags in my car already as an air freshener because I hate those fake chemical scents from the little trees or from the car wash. The chemicals in those fake scents give me migraines. I absolutely love the idea of putting the active carbon in the cabin air filter itself to clean the air. This fits prefecture in my 2017 toyota prius v. It was just a easy to install as any purge cabin air filter. The hardest part is opening all the parts of the glove box to get the old one out. This filter seems sturdier than my last one and it's a good value for the money.

Perfect fit for 2016 Corolla!
Fit's my 2016 Corolla perfect. Has a sturdy frame. Other name brand ones I have purchased before don't have the sturdy frame and squish up. This comes with tiny fragrant beads on the top part and has a light fresh scent when the air is on. Very happy so far.

Good fit, good value
Style: CF12436 Classic, Style: CF12436 Classic
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.
