Biohazard Defense Mode Engaged

Due to wildfires all around our air is now toxic. Made use of the biohazard mode!! Only way we could get out without choking on all the snoke. Eastern Oregon Blue Mountains

Amazing how well it works. Used it when we traveled somewhere in Arizona and fires were nearby a few weeks ago. After about 5 minutes, couldn't even smell it.

WOW, that's crazy.......AQI 641 is HAZARDOUS. CT overcomes again!

It's good to have a truck setup for the apocolypse!

dang, never seen anything near an AQI641.

Winning.

Potential feature: automatic biohazard mode when it gets to a user-defined AQI level

Love it! Use it when following diesel vehicles where we cant breath in the cabin. Only problem is it sets fan to auto which always blows to high for us. Cannot figure how to adjust fan without it taking it out of Biohazard Mode. Does anyone know??

The whole point is the fan is running high as it creates negative pressure

Another feature that makes this an awesome family vehicle.

Dont forget, all of that crap is getting caught in the hepa, carbon and main air filter. These need to be replaced when saturated.

I'd love to know where Tesla actually gets their data and what they do with it. Obviously from over the Internet, but still, the numbers are often much higher than realistic. The AQI scale has an upper limit IIRC (500?), and 641 is well over it. If the calculations were extrapolated beyond the reporting limit, I think that would mean around 700 micrograms per cubic meter of PM2.5. You wouldn't see that far down the road. And it wouldn't be that bright out. We had 600 PM2.5 exactly two weeks ago today from a wildfire 130 km away. The streetlights were on at 6 PM and they absolutely needed to be... it was dark on a sunny day and you needed the lights on in the house to find your way around. The house across the street was just a shape in the murk - visibility was worse than OP's photos suggest. Ash was falling. My guess is those photos above show more than 300 micrograms/cubic meter, less than 500. With a resulting actual AQI less than 500.

This is certainly NOT to diminish OP's experience or the value of biohazard mode... only to say that whatever Tesla is doing to the numbers seems bogus. Watching my own PM2.5 monitor, adjusting to AQI and cross-referencing with local PurpleAir data, my truck is always reporting a number much higher than reality. I'm guessing they pull from crowd sourced sites to improve granularity and probably pull the highest number found, just to be on the safe(?) side... without actually checking to see if it's within a valid range... or from a site that is reporting numbers that don't line up with others nearby.

So smoke bad, biohazard mode good, Tesla AQI questionable.

Tesla did a video many years ago with red smoke to demonstrate the feature when it was first launched as “bioweapon defense mode.”

last week we had a couple days over 800 AQI

Actually I have monitored the AQI from AccuWeather and Airnow...on our area the AQI has read above 1000.
