The Tesla model S and X both now have high-efficiency particulate air (HEPA) cabin filters fitted as standard. These need regular replacement and febi is opening up the opportunity of this business to the aftermarket with two quality replacement filters. 

In fact the Tesla model S and X have both had the option of ‘’Bioweapon Defence Mode’’ since 2018. The main element of this system is a very large HEPA cabin filter that contains separate acid and alkaline gas neutralisation layers to filter out a wide range of contaminants. This filter is located within the front of these Tesla models, (commonly known as the ‘’Frunk’’. When activated, the Bioweapon Defence Mode recirculates the air through the high-quality HEPA filter, purifying it within the cabin whilst avoiding the intake of contaminated outside air. 

All model S and X vehicles are equipped as standard with a cabin filter, which is located within the heating system behind the glove box. However, when Bioweapon Defence Mode is activated, it adds the additional HEPA filter as another layer of filtration.

In addition to the multiple layers of filtering material, both filters for the interior air (including the HEPA filter) also contain activated carbon to remove a wide range of odours and gases. Additionally, when Bioweapon Defence Mode is engaged, the interior fans are operated at maximum speed to create a positive pressure inside the cabin to minimize the amount of outside air that can enter. This process is similar to a positive pressure room in a biohazard laboratory or hospital, preventing the backflow of bacteria and viruses into other parts of the building.

All filters require replacing at set recommended intervals, due to contamination and debris. This is to maintain the efficiency of the system components and, in the case of cabin filters, to protect the driver and passengers for their passive driving safety. The recommended service interval for the HEPA filter is every 36 months regardless of mileage.

febi offers a cost effective, sustainable replacement solution for this HEPA filter. The febi filter replaces the filter media section only. This is unlike the OE part where both the reusable frame and the filter are replaced as one unit.

The filter details are: 

• febi 181979 Cabin Filter (OE: 104556600H SK1). To fit: Tesla Model X Dual Motor (2015 on)
• febi 182548 Cabin Filter (OE: 105933300E SK1). To fit: Tesla Model S (2012 on), Model S Dual Motor (2014 on)

Both febi HEPA filters come complete with installation instructions included in the box. These instructions can also be found online at: partsfinder.bilsteingroup.com

These filters are available from febi stockists.
