ciiyaa Complete HEPA Cabin Air Filter Set for Tesla Model Y(20-Now) / Model YL(25-Now)

How many filters are included?

The listed set contains 4pcs External + 2pcs Internal: six filters in total.

Are all six installed in one compartment?

No. The internal cabin-filter pair and the external upper/lower pairs occupy different positions.

Can I interchange the upper and lower external filters?

No. Match each filter’s shape and position to the removed part and the vehicle-specific instructions.

Does every Model Y or YL have the same filter system?

Do not assume so. Confirm the actual filter housings and fitted system before ordering or starting work.

What should I prepare before dismantling?

Check the complete set, compare the filter shapes and obtain the correct access instructions. Do not open an unrelated housing based only on a general Model Y guide.

Which direction should the filters face?

Follow the airflow markings and the instructions for each housing. Do not apply the cabin-filter orientation to the external pairs.

What should I check during reassembly?

Seat every filter correctly, refit covers and seals, then restore removed trim without trapping cables or leaving fasteners loose.

What should be tested after replacement?

Run the climate system and check airflow, unusual noise and warning messages. Recheck installation if performance becomes worse.

Can this set guarantee medical-grade protection?

No. No medical-protection guarantee is made. Maintain the vehicle ventilation system and follow the prescribed filter replacement guidance.

Is professional installation recommended?

Yes if you are unfamiliar with access to both the external and internal housings. This is more involved than replacing only the cabin-filter pair.
