Tesla’s Service Mode is a feature that allows both users and technicians to diagnose and view vehicle information. With a recent update, you can now view the health of your vehicle’s cabin filter and Bio-Weapon Defense Mode’s HEPA filter.
Cabin Filter Health
To view your vehicle’s cabin filter health data, you’ll need to enable Service Mode. You can follow our guide on how to access Service Mode if you’re not familiar with it.
After enabling Service Mode you’ll want to navigate to the HVAC section. Here you’ll find a view of your vehicle’s entire HVAC system including a health meter for your cabin filter and HEPA filter (if equipped). The health readout is shown as a percentage of health, with a lower number indicating that the cabin filter needs to be replaced. However, we’ve also seen some users report they had a value over 100%. The health meter is intended to provide an approximation of the useful life of your Cabin Air filter.
Tesla likely approximates the health of the cabin filter based on the filter's age and how many hours the HVAC system has been used. It may also consider the fan speed of the HVAC system to account for higher airflow through the filter.
If you have an Intel-powered infotainment unit (~2021 and older), you may not see the HVAC image displayed above, instead, you’ll see one like the image below, which will show you your cabin filter health near the top of the screen.
When to Replace
In general, Tesla recommends replacing the Cabin Air Filter every 2 years, and that the HEPA filter, for vehicles with access to Bio-Weapon Defence Mode, be replaced every 3 years, but this can vary depending on usage and the amount of debris going into the cabin.
Tesla is one of the few manufacturers, if not the only one, that continuously runs air through the cabin filter, even if you’re recirculating air from inside the vehicle. Most other vehicles will only run air through the cabin filter when it’s coming from outside. This helps the air inside the vehicle to become cleaner as it continues to be filtered.
How to Replace
The Cabin and HEPA Air filter replacement procedure is straightforward and could be a DIY task. Tesla provides instructions on a model-by-model basis on how to replace them, but in general, the basic steps are below.
The filter replacements can differ based on model year as well. High-voltage
connections are also passing through the HVAC module, so extra caution is needed. We recommend reading your vehicle’s specific instructions before proceeding. They will advise against touching any electrical connections.
Basic Replacement Instructions
1. Turn off Climate Control
2. Remove the passenger-side floor mat and move the seat fully back.
3. Use a pry tool to release the clips that hold the right-side front footwell cover to the instrument panel, and then disconnect the two electrical connectors inside.
4. Working from top-to-bottom, use a trim tool to release the right-side panel from the center console.
5. A single T20 screw secures the cabin filter cover, remove the screw and cover.
6. Fold the 2 tabs securing the filter away, and then pull the upper and lower filters out.
7. Ensure that the arrows on the new filters face towards the rear of the vehicle, and install them.
8. Proceed through steps 6-1 in reverse to reassemble.
Once again, these steps vary by vehicle configuration, model year, and do not apply to legacy vehicles without a heat pump.
