Original Built-in filter element

The Built-in Filter Element refers to an internal filtration component integrated within a specific system of a Tesla vehicle. This most commonly points to the cabin air filter housed inside the climate control assembly, typically behind the glove compartment. This multi-stage filter combines a particulate layer with an activated carbon element to trap dust, pollen, pollutants, and odors from the air entering the cabin. Unlike "external" filters, this built-in component is part of the vehicle's internal HVAC system and requires accessing the interior housing unit for replacement, which is recommended periodically to maintain air quality and system efficiency.
