    For those of you that want to see where the HEPA filter is located in our X.

    Am curious to know how having a larger air filter helps? They could have sealed more area with metal thus reducing the amount of bad air getting in and requiring a smaller air filter and more trunk space.

    Am I missing something?

    My guess is that in order to pressurize the cabin, there's a required flow rate of incoming air (to overcome outbound air). The filter's flow capacity might require a certain amount of square inches to accommodate that flow. That number of square inches? One million, as you see in the OP's photo.

    All I can say is wow. That is one hell of a filter.

    OK, I've just realized my little Orek HEPA vacuum cleaner bags must be useless.

    The larger filter surface area definitely helps with increasing airflow with less fan resistance while maintaining excellent filtration. That is one impressive air filter!

    Anyone know where the "secondary" air filter is and what the plumbing looks like between them? I feel like we still haven't mechanically seen whether or not there's an alternate airflow that bypasses the HEPA filter. The manual sure refers to the "secondary air filter" ambiguously as if it's the one that's used when Bioweapon Defense Mode is off...

    No wonder the air is much cleaner in my X! It is a very noticeable difference in the smells you smell in my S versus the X.

    That must be $$$ to replace, what is the life expectancy?

    I'm guessing the smaller filter must act as the prefilter for outside air, with most contaminants at least. That said it is general rule of thumb to still replace a HEPA every 1-2 years.

    Is this part of a service plan and documented for MX yet?

    HEPAs can last much longer than 2 years. As the loading increases the filter becomes less efficient at moving air through but more efficient at capturing smaller particles.

    Did you manage to sneak a part number or manufacturer? It might not be Tesla proprietary so we might be able to source it cheaper from another vendor.

    The various bits I've read about the system have talked about activated carbon filter layers to capture acidic and alkaline gasses - I assumed that's what the "secondary filter" was, in which case I'd expect it to be behind the HEPA.

    I was also surprised that the picture doesn't show the 12V battery, which I assumed was on the upper firewall centered, and was told is right near the cut zone on the upper left of the photo.

    I'm missing something. How does the air get to the filter? Doesn't the cover go right next to it?

    This is an air filter. . .

    I'm not 100% certain, but I think it draws air from the gap between the Frunk lid and front face down underneath the Frunk and back up to the filter.

    I believe the air comes if from the bottom of the filter and upwards through it. Notice that the filter frame is a tall triangle with a wide base at the bottom and narrows at the top.

    My guess is that air comes in through the front opening (where the Tesla logo is) and goes down then below the frunk to the air filter, then up through the air filter. This path should help to filter out larger particles and debris before even getting to the filter. I love this design.
