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.

Good as OEM
Size: 7.5" x 8.7" x 1.4"
2024 Sub Crostrek, it fit great. I was so worried, that I need to get the OEM filter, but I went with this instead. Today as I installed the new filter, it looks as good or better than the original. I get that there's more to it than looks, but the quality of the look and feel appear to be matching that of the original, perhaps i might suggest it's even better.

Great cabin filter at a super price.
Size: 7.5" x 8.7" x 1.4"
I trust Bosch for car parts, and for the price and ease of installation, I'd take it over the Subaru OEM part any day.
This is an easy replacement that the dealer would charge x4 the price to do.
