Tesla cabin filter and A/C smell: when to replace and what to do

Interval

How often should the cabin filter be replaced?

• Model 3: every 2 years¹.
• Model Y: every 2 years. If your car has HEPA and carbon filters, Tesla gives 3 years for those².

If you drive a lot in traffic, on dusty roads, or have hay fever, changing it sooner than that can help.

Symptoms

Signs the filter needs changing

• A musty or damp smell when the air con or fan starts.
• Weaker airflow from the vents at the same fan speed.
• Windows that take longer to clear.

A smell that persists after a new filter can come from moisture in the A/C system itself. A garage with air-conditioning equipment can check and clean it.

DIY or garage

Can you do it yourself?

Tesla publishes do-it-yourself guides for replacing the cabin air filters and the HEPA filters on its service website². Follow the guide for your exact model and year, as the filter location differs. If you'd rather not, a Tesla Service Centre or an independent EV specialist can do it, often alongside other checks. See DIY jobs ranked.
