Good OEM replacement for Honda Pilot
Size: 7.5" x 8.7" x 1.4"
Simple cabin filter for my wife’s Honda Pilot. It fits well in the cabin air filter drawer. This is of similar quality to the original Honda one; just cheaper. I’ve bought this for my Subaru and have been happy with it as well.

Works great!
Size: 7.5" x 8.7" x 1.4"
This is a great filter for allergies and a huge help during allergy season. It traps fine dust and pollen much better than the standard paper filters you get from the dealership, resulting in noticeably cleaner air inside the cabin. The construction feels very solid, and it fit perfectly right into the housing without any issues. If you are looking for true HEPA filtration in your vehicle, this is definitely worth the upgrade!

Saved over $60 and felt like a DIY hero!
Size: 7.5" x 8.7" x 1.4"
I bought the BOSCH 6092C HEPA Cabin Air Filter after a tire/service center quoted $76 to do the same job I did in no time. Instead, I watched a quick YouTube video, grabbed a screwdriver, and had it swapped out in under 5 minutes—no sweat, no special tools.
The filter itself is high quality, fits perfectly, and noticeably improved the air quality in my car. No weird smells, and the airflow feels cleaner and stronger. Honestly, it’s one of the easiest upgrades I’ve ever done.
If you’re even slightly handy (or just tired of paying for basic service), this is a no-brainer. Great product, easy install, and a satisfying win for anyone who likes saving money and doing things themselves.

Great aftermarket filter
Size: 7.5" x 8.7" x 1.4"
Performance will be TBD but after a test air does smell a bit cleaner. It Fits a 2018 Subaru Impreza just like the OEM does. Material is significantly better as well. The only thing that will cause confusion is the arrow designation many are used to. The OEM will state which way the filter is to be oriented (up), and this aftermarket version designates which way airflow goes which is usually in the direction of the blower or engine bay (down). Keep that in mind. Otherwise, it’s so easy and such a good peace of mind maintenance item everyone should do and NEVER pay the dealer.

Works ok, but not perfect. Manage expectations.
Size: 7.5" x 8.7" x 1.4"
My goal was to reduce or eliminate bad particulate odors coming in from outside while driving, as drive through areas with high particulate pollution. Sure, recirc mode exists, but then cars fill up with CO2 quickly, and high concentrations of CO2 makes you drowsy and have slow reaction times, etc. So I looked into better cabin air filters.
My Subaru has an easy-to-access cabin air filter. I learned how to properly change it via online videos, because the dealership wants over $50 just to change the filter, and it only takes a few minutes! The OEM filter I took out is not that good, and only meant for larger particulates, to protect the HVAC system. It reminded me of the cheaper (but not cheapest) furnace air handler filters.
Placing this new filter in and testing it, it does block more airflow, which is to be expected from a finer filter. My car's blower has 7 running speeds (plus off), and I needed to turn it up one notch higher to get about the same airflow, versus the previous filter.
The filter seems to work, somewhat. If behind a diesel truck, I still smell it. Same with cigarette smoke from a car in front. It doesn't block vape vapors at all, it seems. However, maybe I was expecting too much. The infographic for this filter clearly shows the size of particulate it can handle, which I appreciate very much. Diesel exhaust is a very fine particulate, smaller than this filter can filter. I also wonder if outside air is getting around the filter in the filter housing, since it just slides in, like a furnace air handler filter. It has a good fit though, in my car at least.
What I need is an even finer filter, but that would likely block a lot more airflow. There are various manufacturers of high-end cabin air filters, but I don't know if they match or exceed the quality of this one.
