2020–2025 Subaru Outback Cabin Air Filter and Engine Air Filter

Which Subaru Outback model years does this cover?

These air filters specifications apply to every Subaru Outback built from 2020 through 2025 — the BT (6th generation), mid-size wagon/crossover (subaru global platform). Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

Where is the cabin air filter on a 2020–2025 Subaru Outback?

Behind the glovebox; drop the glovebox door, 5-minute DIY.

How often should the cabin air filter be replaced on a 2020–2025 Subaru Outback?

Every 15,000–30,000 mi (more often in dusty conditions). Sooner if you drive in heavy traffic, on dirt roads, or through wildfire smoke, a clogged filter shows up first as weak airflow and a foggy windshield that will not clear.
