A Genuinely Useful Diagnostic Technique Worth Trying First — Toyota RAV4 Cabin Air Filter
If you're chasing a musty or damp smell and have already changed the cabin filter without success, this is genuinely worth trying: switch specifically between "fresh air" and "recirculate" settings and see if the smell only appears on fresh air. If so, this points toward the external air intake area (the scuttle, at the base of the windscreen) as the genuine source rather than the filter itself. Debris can accumulate in this intake and block the drain, allowing standing water and decaying organic matter to develop a genuine, persistent musty smell that a filter change alone won't resolve.
It's also worth knowing that a genuine, documented Technical Service Bulletin has covered cases where the metal used within the air conditioning condenser itself can generate a distinctive musty smell, with affected cars under warranty qualifying for a condenser replacement rather than simply another filter change.
Toyota RAV4 Cabin Air Filter: Easy to Forget, Easy to Fix
Of everything covered for the Toyota RAV4, this is about as low-stakes mechanically as it gets — it doesn't touch how the car drives at all. Its only job is cabin air quality, which is exactly why owners tend to ignore it until something makes that hard to do.

Toyota RAV4 Cabin Air Filter: What It Does
On the Toyota RAV4, this filter sits in the ventilation intake, not the engine bay, and cleans the air reaching the cabin — trapping dust, pollen, and on carbon-activated versions, some odours and pollutants too. The engine air filter is a completely different part, serving combustion rather than the cabin.
