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.
