Business Insider recently tested out the Tesla Model X’s “Bioweapon Defense Mode” in “fragrant Manhattan” and reports back that the occupants of the X “couldn’t smell Manhattan anymore” with the mode engaged.

The website wasn’t able to test the mode against actual bioweapons (thankfully), so we still don’t know if it works as Tesla claims, but it does effectively remove foul odors from the air as it enters the car.

What actually happens when “Bioweapon Defense Mode” is engaged? In short, nothing.

Per Business Insider:

“…we wanted to see what would happen when we engaged the feature.”

“But … would alarms sound? Would lights start flashing, like they do when the Starship Enterprise goes on red alert? Would the voice of the navigation system say “Bioweapon Defense Mode engaged!”

“Actually, none of that stuff happened.”

“In fact, absolutely nothing occurred. Total silence.”

The only sign it was on was the fact that the Manhattan stench was no longer finding its way inside the car.

    So is bio-defense mode just turning air-recirculate on? Or is there some super filter it starts passing air through?

    1. Kumar says:

      It has a very expensive HEPA filter if I recall correctly

  2. zzzzzzzzzz says:

    Typical HEPA filter is 0.3 micrometer. Most of diesel exhaust particles are well below that and you can breath them freely, no matter how much Tesla charges for HEPA filter.

    True HEPA filters are maybe $20-$30 at Homedepot, you can cut it and put it in your car if pollen filtering is important to you.

    1. ffbj says:

      Incorrect.

      1. zzzzzzzzzz says:

        Why? Because it is blasphemy to write anything but praise about Tesla for a true cult member? Or do you have arguments?

        You would better don’t write anything if you are unable to write a coherent sentence and make your arguments.

          From TechCrunch : “Tesla had trouble getting any available air testing sensors to even detect a measurable level of particles”

          1. zzzzzzzzzz says:

            They should have hired experts than. It sounds like really silly advertising for idiots. HEPA is standard and has very specific classes, and MERV ratings too, that specify what percentage of what particle sizes are removed.

            1. Andrew says:

              Goodness, did you even bother to read the link provided?

              The filtering, unless they’re outright lying, on the Model X:

              Filtration performance compared to a standard vehicle.

              Bacteria 2.0 micros – 300x Better
              Allergens 1.0 microns – 500x Better
              Soot/Smog .1 microns – 700x Better
              Viruses .01 microns – 800X Better

              This is very clearly beyond a typical HEPA filter. Just because it’s HEPA certified doesn’t mean that it doesn’t perform *beyond* the certification. The HEPA certification means that it performs at least that well.

              Tesla is clearly advertising filtering performance down to 0.01 microns here. The filter is almost three feet wide and six inches thick and takes up an enormous compartment against the firewall of the Model X. It is an extra-cost option bundled with other features to the tune of $4,500 if memory serves.

                Now if only they’d make a zzzzzzzzzz filter.

                  I don’t know why InsideEVs tolerate such well known industrial disinformers..

          You should take your own advice.

          Wow, talk about irony!

          Dude, you’re obviously just copying and pasting ill-informed Tesla basher arguments you’ve read elsewhere. So don’t pretend you’re some kind of expert on soot, bacteria or virus particle size.

          Now, crawl back under the bridge where you live.

        5. ffbj says:

          I agree with that completely.

      Elon goes on to explain that the filtration system will also consist of three layers of activated carbon capable of absorbing hydrocarbons, sulfur and ammonia.

  3. Anon says:

    My understanding is:

    The Model X Air Filter has 3 Carbon Layers, including a ‘Universal Absorbent’ for stripping (anything that’s already combined with Hydrogen Ions) Acidic Gases (Uric, Chlorine, Sulpher, etc.) Alkaline Gases (Ammonia, etc.), and Hydrocarbons. This would be highly desirable in heavily polluted places like parts of China.

    According to Elon, the massive filter is able to trap even small viruses. This is contested by many, btw. The outgoing air is claimed to be comparable to Hospital Operating Room Standards.

    When you activate “Bio” Mode, the cabin is positively pressurized (Intake Fan Speed is set at Max, other intakes blocked) to keep unfiltered air and contaminants out of the passenger cabin. Most people won’t be aware the system is doing anything different, which might be good– if you have nervous passengers…

    This will certainly be all for naught, once someone opens a window or a door, effectively negating anything the filter and fans can do.

    I suppose adding a little Ominous Voice Announcement and Flashing Red Color on the Touchscreen might make a better psychological impression on the occupants, once the feature is activated. Should be easy enough to do.

    1. Rick Danger says:

      It MUST say “Bioweapon Defense Mode engaged” 😀

        1. Kalle says:

          Or “biohazard defence mode activated” in the voice from red alert 😉

    2. Pushmi-Pullyu says:

      The “Bioweapon defense mode” is an amusing, harmless gizmo for a car to have, but I hope nobody takes it seriously.

      It seems extremely unlikely that the small amount of overpressure provided by the ventilation fan is going to be able to fight the wind pressure forcing air into various cracks and holes in the front of the passenger cabin when running at highway speed.

      Is the overpressure chamber inside a biological research lab airtight? Yes. The Tesla Model X? Not so much.

      1. Josh says:

        Positive pressure with inlet filters works really well for paint booths. The concept is sound (as long as those pesky FW door seals hold up 🙂

        1. Pushmi-Pullyu says:

          Hit those paint booths with winds moving at 70+ MPH, and the experience might be somewhat different. Actually, the wind moving over a car at highway speed moves faster than the car, due to Bernoulli’s principle.

          I have no doubt that the Model X’s filtration system works just fine if the car is sitting still.

          1. Omar Sultan says:

            In a car moving into a headwind, there is nothing to “push into” as the front of the car is sealed–the slip steam on the sides, top and back will increase the positive pressure effect because of the venturi effect: any gaps in door seals will cause air to be drawn out of the car. With a car moving across a cross-wind, the wind will push the doors against the seals, increase their effectiveness.

      2. Cavaron says:

        I would volunteer to test it with teargas sprayed at the car. Should go viral on youtube if it fails, but I don’t think so…

        1. Jon says:

          I think that would go viral regardless of the outcome

  4. tsp says:

    Hmmmmm……. A questionable, but potentially very valuable feature in my particular case. A TBI a few years back severed my olfactory nerve, so i can’t smell anything. That would go for the foul smells of Manhattan or my house on fire. The absence of the sense of smell isn’t all that bad, actually, when you stop to think about it. Still, when it comes to noxious fumes outside the vehicle,especially if you’re on a first date, better safe than sorry. Bio-defense system, Engage!

    1. zzzzzzzzzz says:

      It doesn’t filter most harmful fine particles, that is whole point. You would need ULPA filter for that, and it would be big and expensive. It just filters smell, creating illusion of clean air.

      If you want to avoid toxic exhaust better get some BMW model or some other luxury car that turns on “recirculate air” automatically when it senses exhaust gas.

      HEPA filters are good for people with bad allergies and asthma, no that much more. “Biohazard defense” is ridiculous 😉

      1. floydboy says:

        You pronounced that with such authority, I,m inclined to believe you instead of Tesla. Even without a single shred of evidence to validate your assertion./sarc off

      2. Josh says:

        Read Andrews post above (and the links)

      3. Foo says:

        The name “biohazard defense mode” is clearly tongue-in-cheek, zzzzzzzzzz.

        But, that doesn’t mean that it also isn’t probably still the best filtration system you can get ANY car today (short of the presidential limousine, I assume).

        Do you contest that? No? Oh, it’s just an Obviously Humorous name that you so vehemently object to? Well, okay. It’s good to focus on the important things, I guess.

        I’m afraid to know what you think about “ludicrous mode”, then. I mean, even when engaged, the car still appears perfectly normal. It doesn’t look ludicrous at all.

        1. Storky says:

          When in ludicrous mode the exterior reveals a random mix of stripes and polka dots and the sound system blares out the noise of a VW flat four revving and misfiring.

      4. ffbj says:

        Incorrigible.

  5. TomArt says:

    This would be great for just daily traffic – the raw gas smell from vehicles first starting up, such as in parking lots and garages…foul diesel pickups, delivery vehicles, emergency vehicles, etc. I would find good use for this feature nearly every day!

    1. Mathias says:

      Me too! Diesel pickups are the worst. How are you supposed to breath when you follow one?

  6. sven from NYC says:

    “fragrant Manhattan”

    “couldn’t smell Manhattan anymore”

    “The only sign it was on was the fact that the Manhattan stench was no longer finding its way inside the car.”

    Really?
