Perfect fit for 2020 Subaru Outback
Fit my 2020 Subaru Outback perfectly. 5-minute install. Works great. My previous cabin filter was scary to see.

Good, inexpensive replacement filter
I've used these filters for a couple years (four replacements) on my Subaru Crosstrek, and they seem to do the job well, probably as well as the original. I generally remove and clean them every three months, and replace them every six.

Save some money by doing your own cabin filter change! (You won't notice a difference).
So, one day I was getting an oil change at the dealership, and the associate told me that cabin filter was pretty dirty, which I believed because of the places I take the car, and she said that they could change it while they were finishing up the rest of their inspection, since they already had it apart. I asked her "How much?", and then we both had a laugh when she said "$90." I told her I'd take care of it. It took two days for Amazon to get a replacement filter to me, twenty minutes to watch a You Tube video showing how to replace the cabin filter on my car (I watched it twice), and then about twenty-five minutes to replace the filter itself--I keep a messy glove compartment, so a good portion of the time was loading and unloading that nightmare. In the end, under $15 for the filter, maybe 45 minutes to watch and replace, and the cabin filter hasn't been this good since I first bought the car. This replacement version was as good as the OE filter, fit exactly the same, there's no difference in airflow that I can tell, and so far (6 months later), it seems to be holding up pretty well. We'll see what it is like after a year. I did get the oil changed about a week ago, and the technician didn't raise any alarms about the filter, so everything seems to be working. $90 for a new filter? You can do it yourself cheaper.

Fresh Air Upgrade for My 2024 Impreza
Installed this in my 2024 Subaru Impreza, and it fit perfectly—no issues. The air smells noticeably cleaner now, and it took less than 10 minutes to swap out. The carbon and HEPA filtration does a great job clearing out odors, dust, and pollen—definitely an upgrade over the factory filter. The build feels sturdier than the OEM version, though it does have slightly fewer pleats. Might mean it needs replacing a bit sooner, but for the price and performance, I’m fine with that tradeoff. If you’re looking for a quick, affordable way to improve your cabin air, this one’s a solid pick.

Well built, good fit.
I like it so well, I just bought two more to keep on the shelf for when the price doubles. Seems better built than oem, but I don't know how you can judge the filtration; seems good though.
