Which is exactly what the link is about...and I even stated I thought like you until I read about this actually working in California right this minute.

I doubt any of those filters have been changed.

It also appears that you are not reading links, just posting.

Musk credited Google co-founder Larry Page for turning him onto the idea and with the Model X in 2015, Tesla introduced a brand new HEPA air filter system.

The automaker claims that it is about 10 times larger than a normal car filter (pictured above) and it is “100 times more effective than premium automotive filters” as it removes “at least 99.97% of fine particulate matter and gaseous pollutants, as well as bacteria, viruses, pollen and mold spores.”


Notice difference in size between the filter in left and right hand, which you would have seen if you looked at link.
If the car caught fire I'm not sure the occupants of a tesla would have survived if all the air outside was burned up and only carbon dioxide was left. Not sure if the windows likely would have melted in the heat as all the burned vehicles are without tires and windows and are hollowed out shells, not sure a Tesla would have faired better.

Car was moving and was not on fire.

Smoke from the fire was in the compartment which forced the occupants out of vehicle where their almost stationary position allowed their clothes to catch fire.

The degree of filtration is set by the rated standard of the Hepa filter.
You know, that 99.97% from your link, that is a ASTM D2986 spec.
The bosch filter meets the same spec. And as for filtration capacity (litres per minute or ft³/min), I've shown you the graph where the tesla test results are compared to the 2010 mazda stock filter result. There isnt much more to the entire system. The 'System' is a filter and a fan. So there's a filtering degree (in this case ASTM D2986) and a flow rate of air, where you can see in the graph that what the tesla system does in 2min, the system in the old mazda does in 3 min. Thats it.

But I suspect you don't have a technical occupation. You're not a techie.
You dont seem to process this data the way I process it.

Put a $75 HEPA unit in your den and use it for a week and then put a $500 High Quality HEPA unit in your den and you can tell night and day differences.
Both have a HEPA rated filter...
Thats because 'HEPA' itself is a loose claim. It doesn't say anything. HEPA is NOT a 'rating'.
It just means "High Efficiency Particulate Air", nothing more nothing less.
Thats why there are independant set specs for it (or ratings how you call it). Thats what you have to look out for. So there is the ASTM D2986 (thats a US spec; that 99.97%, the one both Musk and Bosch claim to) but for example in europe they have a much more elaborate system (EN 1822:2009) where they divide it into 8 seperate classes ranging from E10 (>85%, so much less than the US ASTM D2986 spec) to U17 (> 99.999995%, way more than the US ASTM D2986 spec). (those filters with really really high filtration degree sometimes also are called 'ULPA')

Thats how these specs work.

I never said it works as well as the Tesla feature. What the tesla feature does in 2 minutes, a normal car can apparantly do in 3 minutes. Just look at the graph.
My point is that Musk claims that that is '100 times better', and you seem to agree.
So either Musk has, with his physics degree, the mathematical insight of a 4 year old, or he is making up all kinds of numbers in order to sell his stuff and get into the media. I gave you links where specialists debunk the things he says on this, and still you seem to fall for it.
