- Explore the science behind how gas masks work, and how the technology protects us from airborne threats and pollutants.
--
You might think of gas masks as clunky military-looking devices. But in the near future, we may need to rely on these filters as part of our everyday lives. In addition to emerging diseases, wildfire frequency has more than tripled, and climate change has increased toxic ground level ozone. So how do these masks work, and can they protect us from airborne threats? George Zaidan investigates.
Lesson by George Zaidan, directed by Michael Kalopaidis, Zedem Media.

I have never felt more like we live in a dystopian sci fi world than after watching this video. What a nightmare world it would be if we let it get to this point.
But cheap flights and private cars! Cheap clothes and products! We are currently watching and do nothing
Not to insinuate that human activity hasn’t produced more wildfires, but wildfires have always been a problem like earthquakes or tsunamis, at least now we have ways to mitigate the damages.
@@estoniaisunderrated5120 I mean, the 3x part is a major factor. I've never been impacted by a tsunami or earthquake, but everyone I know has had at least a few summers smoked out. They're just so much more common
Prolly not gonna be part of our generations problem.
not 'IF', 'WHEN'.

I love how they paid attention to even the smallest details, like accurately depicting the type of bond in each molecule.
Hate to be that guy, but technically, the bonds for nitric oxide and nitrous oxide are depicted incorrectly:
1) Nitric oxide has more of a double bond + a free radical (•N=O), though the radical can sometimes be depicted as a third bond (drawn as a dotted line, NOT solid line!) to show "resonance".
This dotted line is shown correctly for ozone as it resonates between (O=O-O) and (O-O=O), thus the structure can be "averaged" to give a dotted line throughout the ozone molecule.
2) Nitrous oxide can be drawn as (N=N=O) or (N≡N-O), but NOT a single bond (N-N-O)!

Tru , maybe the animator searched it from google
@@henrythepotatoheadShh. Let him cook.
TEDed animations are the reason why i watch their video. Straightforward, and simple design. Deserve an award!
I watch them for the information, the narration and the animation
What's with American culture and 'awards'. Not everything good needs to paid for.
Same. To the point animations and easy to understand
This feels so horibly distopian it's insane, getting genuine chills from this.
Stop watching and go outside, I promise it is nothing like this video makes it seem
@@oerlikon20mm29 Well. In wildfire prone areas, the outside looks like how the video showed a few weeks or months out of the year during wildfire season.
@@oerlikon20mm29it very much does depending on where you are.
Did anyone else find this extremely creepy? It reminds me a bit of the fallout 2 intro. This is essentially the modern version of those nuke drill videos from the cold war.
Not really? It is just you
I feel you. Hopefully its predictions don't come to pass.
@@gryphonbotha1880 Predictions? Where I live it is a reality every summer! The sky gets red and one time it actually rained ash.
@@EmmettCoughlan Woah! Where do you live?
Yeah, I kind of see your point. They’re both man made horrors and both have the chance to wipe us off the planet. Although I think the whole “duck and cover” method of those nuke drills were a lot less useful than knowing about and having access to masks and other modern advanced filtering technology. Hopefully we can stop climate change like how we’ve worked to disarm our nukes. Humanity usually finds a way to prevail in these situations, even when it seems too late.
I definitely recommend the poem, "Dulce et Decorum Est," by Wilfred Owen, which depicts the haunting and horror of chemical warfare in WWI.
Yeah, -although forgetting the “pro patria mori” part!-
Great poem, thanks
@@slugintub1541 that's the title of the poem, the last line is the full quote
There’s also a choir piece by Larry Nickel (a Canadian composer) based on the poem that I find really captures and even elevates the intensity and atmosphere the poem conveys.
It’s a good poem

If it’s gone to the point where we have to worry about wearing gas masks in daily life we’re screwed.
Someone else who just realized it
We're very nearly at that point as it stands. I think we're in for an even smokier summer than last year 😷
It honestly looks like an exaggeration, at least in the US. Wildfire number is pretty consistent according to the United States Environment Protection Agency, bouncing around 70,000 per year since they started watching in the 1980s. The area burnt has gone from about 3 million acres to about 8 million, but that's nothing compared to the 2.4 billion acres of US land. Some states even averaged proportionally less land burned since 2002.
Maybe it's a bigger concern somewhere else, but it's not very concerning where I'm looking.
@@ToudaHellTime to bring out the Mustard gas blockers again…
the lowest daily average in Southeast Asia last month is 33°C (91°F) and we haven't even got the wildfires on yet. Beautiful weather around these parts.
It's important to remember that none of this applies to standard paper masks. This technology is exclusively found in "respirators" IE - N95, KF94, P100 etc
Bro when will you make a new video i enjoy them
@@paradox602tomorrow
Love gasmasks for its aesthetics
it is like a modern plague doctor mask
@@Michaelonyoutub I love gasmasks mainly because they're connected to ww1. Also they're a perfect intimidation cosmetic for special forces units
@@gabriellegomez2005 love rocking the gp 5
I don't know what's aesthetic about not being able to breath naturally
@@Michaelonyoutubplague doctor masks are different
"And in the near future, we may need to rely on these filters as part of our everyday loves."
Pollutants from factories and traffic not even mentioned, only wildifres and diseases are affecting us??
I mean, these are important factors when it comes to air quality but come on.
Depends on the place I guess. Pollutants from factories are less of a concern in the West, while are certainly an acute issue in places like China & India. Maybe they're just catering to their largely American audience.
I mainly use an air purifier for minimizing dust in the room and internals of my desktop PC, on top of daily vacuuming. This reduces dust buildup and need for cleaning. However, in areas where there is less air movement, dust still do accumulate over time.
Yep. Dust is everywhere!
environmental engineering senior prepping for her aerosol science final next mon, thank you for helping me revise!
I would say good luck, but you don't need luck when you've prepared. You'll do well, and I hope that you stay in the field or go into another field where you can help make the world a better place.
Isn’t all engineering environmental in a sense? 😂😂jk
I have a similar masters from Appalachian State University! I’m now work on a community scale wind, solar, and geo thermal pre construction contracting firm and I love love love what I do!
That's a dope degree
As a Wildland Firefighter we do not travel with our own air supply. As a Vol Firefighter, yes we do go in structure fires with our SCBA.
do not let this video distract you from the fact that mr.krabs sold spongebob's soul for 63 cents
💀
good price

Unforgivable
Very reasonable
Imagine fighting in WWI before anyone knew about gas then the German unleash it on you. You have no idea what is happening as everyone is dying around you then it hits you. That must have been terrifying and you cannot run because if you go above the trench then you are going to get shot and die anyway.
Well, chemical weapon in WWI was firstly used by the French military on August 1914. It was chloroacetone.
I just recently watched about diver underwater regulators
A kinda_dystopian-ly_animated video that talks casually about the world being orange, people wearing masks everyday and everywhere being the norm, and fires happening constantly, in large scale, and near your house, with its smoke haunting every single part of the city.
That's probably the scariest and most effective argument I have seen regarding air pollution. If the numbers really show that that's our near future, I'll be very convinced that this is a priority. I don't wanna live in that world. Suddenly, I see the importance of being able to breathe without getting sick, to breathe without a mask (they're sooo uncomfortable), and to have a blue sky.
I always thought it was silly to be an anti-masker during COVID. When you had a cold as a kid and sneezed, your mother would yell "Cover your mouth!" She wasn't trying to take away your constitutional rights or topple a president. She just didn't want to catch your cold.
Your mother didn’t threaten to fire you from your job or kick you off airplanes or shame you from polite society.
Also, her focus was manners, not epidemiology.
@@Btburkhardt I'd argue it's good manners to not expose others to your illness
@@Btburkhardtyou are arrogant. & don’t care about others safety. Say a lot abt u.
@@Btburkhardt wow you know his mom almost as well as I know yours. Also, were you one of these whiny bitches complaining about masks because you were too dense to recognize the severity of a virus killing millions of people?
@@Maria.Mirabella cloth surgical masks did nothing to prevent the spread. Scientifically proven. It’s not good manners to demand people to wear things that don’t even work. I believe that’s called insanity. But generally I agree with you.
Finally another TED ED video!
I AM GOING TO BUY ONE AFTET SEEING THIS. Seems like a useful thing
Nice video!!
1:21 tell that to any wildland firefighter and they would laugh in, let out a cough and say when did we get air packs for wildland.
Great educational content as always! 😁
I always wondered about gas masks and how they worked
This video was breathtaking. :D
Great Animation. Always
Very interesting video, thanks !
The van der waal force might be what clumps aerosols together but this is not part of the filtration principles. Air filters work by interception, impaction, diffusion (brownian motion) and electrostatic forces (depending on the media, aerosols and media condition).
Your analogy of representing the media with a forest is spot on, it is how I explain things to my customers, a 1 micron particle going through 1mm of media is like a fly flying through 1km of forest (roughly speaking), the odds are practically nil that it will make it across but the air can still blow through.
I always wondered why ozone isn't a ring structure at the atomic scale...?
Great video by George Zaidan et al. again, well done!
the bonds would be too tight in ozone if it was a ring and resonance helps it stay more stable not in a ring
Good video.
It reminded me of that covid era. 😢
Yeah, this video will trigger the anti-maskers ("Masks don't work because the virus is too small!") and the Climate Change deniers ("Climate Change isn't occurring because it snowed where I live!").
Thanks for your presentation
Can confirm, gasmasks work.
this is such a sad yet necessary video
Are you my mummy?
Best comment
I understood that reference
Please mummy let me inside, I'm scared of the bombs.
Everybody lives!
What on earth!?
I love how they have "how do gas masks work" as the title. But most of the thing just talks about regular masks that arent gas masks, and doesn't go into any real detail on how they work either.
For those who have bought a military grade gas mask you need to be careful with the filters as some contain asbestos. Just avoid any filters made before 2000 and avoid Soviet/Russian filters as those have been proven to contain asbestos.
good content !
Thx
Quality content. Kudos :)
Very interesting facts and stories told in animation .
Like to watch.
nice video
The Gas Masks from The 2nd World War always freak me out because of a Dr Who episode involving them I watched when I was younger with my older brother.
I’ve always found gas masks to be really cool and intimidating, most notable the ones used for military.
i tought it was really something like how military gas masks worked
That animation was incredible... but it was also really, really depressing, haha.
Interesting
George from Reactions!!
Hey Ted -ed sugestion to next history video:Los Angeles ritos of 1992.
That the 13% started and always start.
*Los Angeles Uprising of 1992
@@whathell6t 13% of 60%
cool.
3:27 So, can the activated charcoal be treated with a buffer solution to trap acidic AND basic compounds?
N95s don't actually stop only 95% of normal particles.
They are rated on how well they can stop particles of 0.3 microns, which are the highest penetrating particle, do to exceedingly small ones basically ricocheting of the surrounding air.
❤ Awesome as always thanks
4:05 - Rosenthal is actually pronounced ‘Rosentile’.
I'm scared for the future
Nobody:
The quite kid with mask: *Wait till you here the fire alarm, bozos*
The old heavy voice narrator is the best. I listened and saw in the some recent videos but why again he is not doing it! 😭😿.
most relevant video almost after 10 years from now. 😢
good!
I was waiting for the chlorine gas part
Good video, but most firefighters don’t carry air supply in brush or wildfires
where was this video during the covid pandemic when i had to tell people why wearing masks is important. very cool video
Its crazy how we have to engineer ait purifers just to survive, this world already feels so dystopian
This watches like one of those vault boy animations from fallout
Just so you know, wildland firefighters don't travel around with an air supply. They do their work with no protection.
but, how accurate is pollution indicator? like, the sensor doesn't cover wide space, so a few meters, the pollution concentration might be different?
They never explained how charcoal based gas mask work most military use a charcoal filter
Can you make a video on refraction of light it's hard to understand please teded please❤
We learnt that in 6th grade…

How do funky even we need to worry breath?
maybe you own a gasmask... yes a soviet pipe filter
I don't know if anyone has done it yet, but I feel like I must: ARE YOU MY MUMMY?
I know one thing for sure. They dont stop covid or the smell of farts😂
Reminds me of the days in city of Ulaanbaatar the air was so bad that the city advised people to wear masks not to get Carbon Dioxide and other chems into the sky. But i dont see them nowadays but the pollution still linger on.

I was not expecting a comment like this in this video 💀
Astounding 😃
😃
They gultwr the mustard out of the gas so that you can put it on a hotdog later
Everyone: Oh no wildfires!
Only madrone trees: 👍
so they werent made to use for the gas zone in cod?
I came to learn about gas masks and left without learning how gas masks work...
Hey it's the milk wash guy.
This, the Bayonet, and the Shovel are all that is needed to bring the Emperor's Wrath to Heretics, Xenos and the forces arrayed against humanity.
This video showed up in my feed after doing a binge on the Siege of Vraks by Janovich.

Damn, thanks for ruining my morning. I thought we were going to just talk about how gas masks work, not how we’re doomed.
3:17 not For tryphobia ( fears of holes)
Then you got those unnerving Mickey Mouse ones... totally creepy despite the fact it was to keep kids calm.

The beginning quote refers to blood and water i guess, right ?
I think water and air. A fluid can be a liquid or a gas.
The two fluids are water and air.
this is a filter mask, not a GAS mask
when there is a bad air quality stay insides....
meanwhile Delhi : we got this
Now I finally understand why face masks have a lifespan. I love how Ted makes me feel smarter
,':)
I really wish everyone did this reasearch when everyone was refusing to wear a mask.
I know what you may be thinking, whats in the canister?
Ayyy
1.39 Wait. 2.5 micron, but most only stop particles 3 micron or bigger
Can we make a filter that takes normal air and extracts oxygen.
yes but it would be wildly impractical e and you wouldn’t want it. breathing pure oxygen for extended periods of time is toxic.
@@blank_3768 I want oxygen as rocket fuel🚀⛽
the only way you can do that is by liquefying the air and pouring it over a strong magnet
@@i_am_a_toast_of_french Can yo elaborate on the reason?
@@i_am_a_toast_of_french that’s not true. there are many ways to separate out pure oxygen, it’s just they are all wildly impractical
👍
They work better during drills, when you dont have a cannister attached, because you can catch somebody sleeping while waiting for the drill to be secured and fart in the hole.
