On a 2015 Model S, the cabin filter hides behind a magnetic panel in the right-front footwell — the airflow arrows point toward the rear of the car.
Most do-overs on this job start with one small thing: a filter seated backward. The part drops in either orientation, and only the printed arrow settles which way is correct.
Tesla’s DIY page walks through how to replace the cabin air filter in a 2015 Tesla Model S in a short run of steps that need no tools and no shop visit. What follows is the exact order, the two checks that keep the filter door sealed, and the reset that clears the service reminder.
Where Is The Cabin Air Filter In A 2015 Model S?
The cabin filter sits in the right-front passenger footwell, behind a cover held on by magnets. The part isn’t under the hood, and nothing beyond that cover and the filter door behind it has to come apart.
The interval is time-based, not mileage-based, which is why a low-mileage 2015 Model S still comes due. Tesla’s Model S DIY cabin filter procedure sets the replacement at every two years — every year in China — and sends buyers to the Tesla Shop for the filter, with shop.tesla.cn serving China. Tesla’s documentation doesn’t publish a filter price, so treat retail listing prices as seller-set numbers rather than Tesla’s own.
You work from the passenger side with the seat pushed back, so most of the job happens on the floor mat rather than under the car. If you’d rather have the replacement in hand before the cover comes off, tested 2015 Model S cabin filter picks compare fitment and what each option includes.
One build-date rule is worth knowing for context. Tesla’s service manual splits underhood particulate filter work at an April 10, 2016 build date, and that split covers the underhood particulate and HEPA system, not this footwell cabin filter.
| Detail | What Tesla’s Documentation Specifies |
|---|---|
| Replacement interval | Every 2 years; every year in China |
| Filter location | Right-front passenger footwell, behind the magnetic cover |
| Airflow arrows | Face toward the rear of the vehicle |
| Door check | Lock fully engaged and door sealed shut before reassembly |
| Parts source | Tesla Shop; China buyers use shop.tesla.cn |
| Final step | Reset the cabin air filter interval in Maintenance Summary |
| Aftermarket fitment | Listings cite 2012–2015 or 2012–2016 Model S; only Tesla confirms fitment |
Model S Cabin Filter Replacement: Step Order, Arrows, And The Door Seal
The sequence Tesla documents runs from the seat to the cover to the filter door, then ends with a reset inside Maintenance Summary. Work it in that order and the harness and magnets cooperate instead of fighting you. Every action happens inside the cabin, and the only electrical part in the chain is the connector on the footwell cover.
- Turn climate control off.
- Move the front right-hand seat fully rearward to open up the footwell.
- Pull the footwell cover down gently. Magnets hold it, so it releases with a steady tug rather than a pry.
- Disconnect the harness on the right side of the cover, then set the cover aside.
- Release the cabin filter door lock and remove the door.
- Slide the old filter out.
- Seat the new filter with its arrows facing the rear of the vehicle.
- Refit the door and check that its lock is fully engaged and the door is sealed shut — Tesla names that seal as something you verify, not assume.
- Reinstall the cover, reconnect the harness, and press the magnets back into place.
- Return the seat to its original position.
- Reset the cabin air filter interval in Maintenance Summary.
A cover sitting flat over its magnets and a fresh interval showing in Maintenance Summary are your confirmation that it worked. That reset is also the only part of the job that touches the touchscreen; everything before it is hands-on.
Mistakes That Force A Second Attempt
Three errors send people back into the footwell for a second try, and each one takes seconds to avoid.
- Arrow direction. The filter’s airflow arrows face the rear of the vehicle, and installing it backward is the error Tesla’s guidance calls out.
- Filter door seal. Tesla says to confirm the door lock is fully engaged and the door is sealed shut before the cover goes back on. A door that isn’t fully latched can let air slip past the filter.
- Harness handling. The cover carries an electrical connector on its right side. Leave it attached and the cover dangles by its wiring.
Fitment deserves its own caution. Third-party parts listings often describe cabin filters as fitting 2012–2015 or 2012–2016 Model S, but those listings aren’t official Tesla fitment confirmation, so check the part against Tesla’s own guidance.
FAQs
Do I need any tools to get the filter out?
No. Tesla’s procedure releases the footwell cover by hand — magnets hold it, and the electrical connector on the right side unplugs without a tool. The cabin filter door releases on its own lock. The only thing you need on hand is the replacement filter itself, and the job finishes with a reset in Maintenance Summary.
