when changing the filter yourself, do you need SC to an over the air update to have the tesla notice that there is a HEPA filter?
No. Air simply flows through the new HEPA filter, it gets used without any need for SC attention.
Any software change is just to enable their "Biohazard" button (which is just a macro that enables recirc and turns the fans up).
SCs no longer offer the retrofit, and thus no longer offer any OTA updates for the "Biohazard" macro button. The $750 "Biohazard" button is not needed to get the benefit of HEPA...
