🛡️ Tesla Model X HEPA Filter Replacement | Cabin Air Quality Service

👁️‍🗨️Overview

A Tesla Model X came into our Concord facility for a scheduled HEPA filter replacement. The driver had noticed reduced airflow from the vents and an increase in cabin odors — common signs that the filter had reached the end of its service life. The HEPA filter is a crucial part of Tesla’s Bio-Weapon Defense Mode, keeping airborne pollutants and allergens out of the cabin.

🔍 Diagnostic & Pre-Service Check

Our standard inspection revealed:

1. Reduced airflow from cabin vents

2. Increased HVAC fan noise

3. Faint odors inside the cabin

4. Last known replacement was over 2 years ago

   
   

Upon removal of the upper frunk components, we confirmed the original HEPA filter was heavily contaminated with visible dust and debris.

Performed by our trained Tesla technicians:

1. Powered down the vehicle and disabled HVAC system

2. Removed frunk liner and windshield cowl to access the HEPA chamber

3. Disconnected front high-voltage safety loop for technician protection

4. Removed old HEPA filter and cleaned the housing

5. Installed new Tesla-approved HEPA filter with OEM housing cover

6. Reassembled all parts and cleared service area
