Where is the air filter in a 2021 Nissan LEAF?

• Cabin air filter: located behind the glove box or under the dash — it filters outside air before it reaches the passenger compartment.

• Service benefit: our certified technicians use OEM parts and explain which filters your LEAF requires, preserving performance and warranty coverage.
