Interesting. Can you also check what P3 particulate filters look like, after being used in a dusty environment, say, a welding shop. I want to see what size and shape the metallic and nonmetallic particles have.
It's so strange to think that whatever the mask has caught, we usually breath in When I went to school, after 6 hours of continuously wearing the mask, a dark layer would develop near the nose, it was disgusting Nevertheless, awesome video!
Probably just sweat and dirt. There’s naturally going to be some edgy anti-maskers, so it’s worth pointing out that studies have shown that they work, including for individuals (even when crowds are maskless) and in real-world conditions as opposed to laboratory ones. Bit pointless me saying it though, those people don’t really care about “logic” and “science”. They’re too busy breathing in the QAnon cult. I say we put them in some island and dunk diseases there, see what they think then.
I remember when covid hit and there was an N95 shortage on the covid unit, we had to don and doff the same mask over and over again. They told us we were allowed one mask per day, and we could reuse that one mask up to 4-5 days in a row as long as we put a regular mask on top of it. Looking at what’s grown on those Petri dishes, it really puts things into perspective.
@@freedomisntfree_44 literally because that's not the purpose of the masks. surgeons do NOT wear masks to protect themselves while doing surgery on someone. surgeons have been wearing masks for nearly a century now to protect the patients who's innards are exposed and vulnerable to otherwise benign bacteria that a surgeons breaths out, sneezed, coughs, etc. and they wear them for up to 16 hours or more.
@@freedomisntfree_44 that's for liability purposes... The most important thing with a respirator or mask is good fit/seal on your face. And even then there's no 100% guarantee you won't catch it. The whole point is to reduce your chances
Would love to see the condition of the mask in various stages, say after 1 "use" versus 5 "uses", maybe 40 hours would be better? Absolutely loved the electrostatic demo, super cool! One minor caveat is that these masks actually filter the worst at 0.3 micrometers. Anything smaller easily collides with the fibers due to Brownian Motion, anything larger is collected through impaction or electrostatic attraction. That's why these masks are tested at 0.3 micrometers... if it gets a 95% at that size, it probably gets much more at any other size.
Some sizes are filtered out better than others. There are a lot of nuances so I try to be very general given the limitations of presenting information through text on a screen. That's why I also included references.
@@datHDgameplay Where did you get the 8 hour figure from? Aaron Collin conducted filtration tests on 40 hour KF-94 masks and they only lost a few percentage points of filtration.
@@GearsDatPowerDaTubes I got it from the enclosed instructions. you see yellow it's an 8 hour mask. you see pink, it's a 40 hour mask. I wore p100 masks for the first few covid months. Those were 40 hour masks and have a pink label.
What's even more amazing is the fact that all this gunk is filtered through our nose and the rest of our respiratory system while we keep breathing every second of every day!
And this is why the mask is not needed. The nose filters everything just right in fresh air and if you put a mask on you just suffocate for no reason and breathe the stuff that should be out.
@@CyanideOwl the nose absolutely does not filter everything, it does a good enough job but things can still pass through, and a mask doesn’t block out oxygen in any way, O2 molecules are much smaller than viruses and other particles, and they can easily pass through the mask’s fibers, same goes for CO2. Our nose filters particles smaller than 5 microns and larger than 0,5 microns
Once every few months should be a "catch up day" where students who miss class because of illness can get the lessons missed. They can miss school without worrying that they'll fall behind because the system is setup without measures in place to help kids who miss a few days of classes.
Great video! So informative. I've tried to explain the aspect of the electrostatic charge many times to people skeptical of these higher quality masks. That seems to be a feature that in particular can help with the extremely small coronavirus particles which can get through most filtering, apparently. Also, you wrote this music? I love it! Especially where you have a bass walk down over the guitar plucking starting at around 4:52 Fantastic, beautiful, and well done.
i was doing my internship at the hospital during Covid & had to wear this mask for hours. it's fascinating to see what get caught underneath the mask in microscopic view, thanks for sharing this!
Is it possible for a medical grade mask to be compostable? I understand that single use is necessary in the medical field, but I’m just wondering if it’s even possible to phase out plastic waste there. There’s so much. Masks, isolation gowns, gloves, caps, needles.. sooo much. Is there a sustainable material that can be waterproof?
For now, I don't think we have the technology. A high enough density is needed in gowns, gloves, and caps so nothing can seep through nor go through, and most of available natural materials can't really provide that. The mask in the video as you know is made of a mix of polyester fibers, which does a great job of trapping bacterias and viruses (which is also the reason pet owners rarely use plastic feeding bowls), and a cloth one doesn't have the same efficiency.
@@melovetorun True, but at least it's for a good reason. I don't think we should tackle plastic pollution from the healthcare angle when there are sooooo many more angles that waste more and use plastic in completely avoidable ways. My pet peeve is plastic trays in cookie packaging.
Love these videos. Keep them coming. Have you done fridge filtered water? I measure it and then my RO system. Fridge water measures 50% better than tap water in my area, but RO measures 99.3% better than tap water.
I'm just a passing scientist with some thoughts and I have no knowledge of how N95 masks are produced nor do I intend to look too deeply into it. But I do have some thoughts just based on this video: @2:48 I'm sure they've already done testing to show that charging the fibers makes the masks more efficient at filtering debris. I'm curious though because I would imagine that it should have the opposite effect. Imagine bottom-feeders; they have these hairy fibrous appendages that they wave around in the water to filter food out which they then eat---the purpose is to catch food that is passing through the water by collecting them in one place. If the mask is charged, wouldn't that be functionally the same? For the magnet you found, would that have passed through the mask and been inhaled by the you if the mask wasn't charged? Would it have even been there in the first place if the mask wasn't charged? I imagine you would want the mask to repel debris away from you, not attract them. I imagine their experiment would have been something like: (1) An enclosed tube with an opening on one end (2) A device measuring the number of particulates in the tube (3) A mask is placed over the open end of the tube (4) They simulate an environment with a high number of charged particles (maybe something like fiberglass which you would find during home construction) (5) measure the number of particulates that get into the tube without an N95, with a non-charged N95, and with a charged N95. @4:16 This experiment only shows how well the N95 masks blocks bacterial contamination since viruses need a host cell to replicate; they cannot grow on plates by themselves. I imagine for testing against viruses, they would have used what's called a viral plaque assay: (1) a lawn of bacteria is grown on a plate (2) A known quantity of bacteriophage is pushed through the N95 mask (3) They then measure how much bacteria is killed compared to a control group where the bacteriophage was not pushed through the N95. @5:19 A lot of the colonies from the inside and the outside of the mask look like they are from the same type of microbe; how do we know that the ones from the outside of the mask aren't just the microbes that you are breathing through from the inside of the mask? I think the best way to show this would be to have a sterilized mannequin wear the mask and then to swab both inside and outside after a time. That way you know the mannequin cannot be a source of microbial contamination and that if the N95 is truly filtering, then the inside of the mask should be cleaner than the outside. Anyway, good video. It's always good to expose more people to science.
The charge isn't strong enough to attract particles outside of the air current. It is strong only in very short distances (look up inverse-square law). Viruses do not commonly spread as flying single viruses, but within tiny droplets. There are several studies demonstrating that masks do prevent viral infections.
Woooo another video (with another banger music track, of course)! It was actually really interesting to see the fiber structure that comprises the mask itself
Can you try various canned foods (canned fruits, tuna, sardine, SPAM, etc)? Wondering if we could see the cooked bacteria corpses or if the harsh canning processes obliterates them

My understanding is that rejection of cloth masks-- which lack the features of the mask in this video -- is usually their main point. Medical grade masks are generally acknowledged as helping reduce inhaled particles. The argument is that whether the amount of reduction is worth the cost of wearing the medical grade mask. They would probably say that decision ought to be left to individuals.
Really cool to see! One thing I do wonder is if you breath in the fibers the mask is made of? Is it made from plastic? Or are all the fibers so strong that it's impossible to loosen and end up in your longs? Greetings & thanks for the interesting video xx
@@ShiratoriIsOffline Well that filter only work efficiently on non-biological particles. Whereas bacteria and viruses would just gets stuck on those filter and grow there, that's how you get infection and then it's now the immune system to be depended on in those infection matters that came from those mucosal particulates from those filtering.
I may not like the results of this experiment but it is still interesting to see. I wonder what the long-term effects of breathing in polypropylene particles are though.
Can you do the same thing with KN95's, surgical masks, cloth masks, and neck gaiters? What about how dirty hands are before and after hand sanitizer, disinfecting wipes, or other things related to the pandemic?
KN95 is exactly the same as N95, it's just made in Korea, and has been certified for Korean regulatory compliance. Functionally, and physically, they are identical in material and filtration.
Good about hand sanitizers. Also i would expect him to have microscope where one would be able to see bacteria and viruses, not the one for children to play with

I am interested to see what would shampoo look like under the microscope, considering some shampoos have antimicrobial compounds in them such as zinc pyrithione and piroctone olamine, I'm curious what would happen if you spread them throughout a petri dish and see what would grow.
Well on last culture plate there are some colonies of fungus and other colonies can be normal flora like staph.epi from skin and from mouth they can be lactobacilli, staphylococci etc
I'm rreeeeeeaaaallly curious what tonsil stones would look like under a microscope. Seems interesting since tonsil stones have a lot of bacteria in it.
I didn’t see any virus or bacteria caught in microscope therefore it seems like a proof of being ineffective - if you look at mere size of viruses it is like a mosquito going through a chain link fence
Love your channel and content. As a nurse who has worked through the thick of COVID the last 3 years, on a COVID unit, and wearing the N-95 masks for hours long each shift, I can attest to it's ability to protect the wearer. Long story short, I was the first to a code blue situation for a covid patient wearing only a surgical mask (in times of crisis, sometimes we tend to forget about ourselves and focus on the person in need) and had began CPR. Minutes later when I was relieved, fellow colleagues mentioned to me that I need to put my N95 on in which I did but didn't think nothing of it after the event. 3 days later, I tested positive had a terrible 2 week long recovery. Luckily, I didn't have to be hospitalized or deal with any major complications, but the fact that I knew what covid does to people had me worried and thinking about it every single day until I recovered. Masks do work. We are in a recovery time, but it's not time to get complacent. Stay safe all.

Really cool to see! One thing I do wonder is if you breath in the fibers the mask is made of? Is it made from plastic? Or are all the fibers so strong that it's impossible to loosen and end up in your longs? Greetings & thanks for the interesting video xx
I'd guess the electrostatic charges would handle that.
The respiratory system has excellent filter
@@ShiratoriIsOffline Well that filter only work efficiently on non-biological particles. Whereas bacteria and viruses would just gets stuck on those filter and grow there, that's how you get infection and then it's now the immune system to be depended on in those infection matters that came from those mucosal particulates from those filtering.
@@vicovideocompilationsetc6991 that's what op is asking
@@vicovideocompilationsetc6991 rather, what op is concerned of. Since like you said, it's only efficient on nonbiological particles.

Welcome back
Yes! Another upload!
What a great video!!! Thank u soo much! ❤️
Hey, new video! I really like your content
I may not like the results of this experiment but it is still interesting to see. I wonder what the long-term effects of breathing in polypropylene particles are though.
Can you do the same thing with KN95's, surgical masks, cloth masks, and neck gaiters? What about how dirty hands are before and after hand sanitizer, disinfecting wipes, or other things related to the pandemic?
Yes!
Plandemic*
KN95 is exactly the same as N95, it's just made in Korea, and has been certified for Korean regulatory compliance. Functionally, and physically, they are identical in material and filtration.
Good about hand sanitizers. Also i would expect him to have microscope where one would be able to see bacteria and viruses, not the one for children to play with
@@bigbuckoramma kn95 masks are around 60-70% filtration.. i think. they aren't true n95 masks. better than surgical masks though.
Time to whip out the half a million dollar electron microscope
I am interested to see what would shampoo look like under the microscope, considering some shampoos have antimicrobial compounds in them such as zinc pyrithione and piroctone olamine, I'm curious what would happen if you spread them throughout a petri dish and see what would grow.
Well on last culture plate there are some colonies of fungus and other colonies can be normal flora like staph.epi from skin and from mouth they can be lactobacilli, staphylococci etc
post rock my beloved
sick videos, and sick music 🔥
Thank you for the video bro! Keep up the great work please!
Good job...
Best music
You should do a video on water bears and see how much punishment they can withstand before dying. They say water bears are nearly invincible
I'm rreeeeeeaaaallly curious what tonsil stones would look like under a microscope. Seems interesting since tonsil stones have a lot of bacteria in it.
Great content! All your vids are interesting and I like the music you make too ❤️
Bro you always be picking fire music fr
*always be creating fire music
ftfy
Now imagine how dirty our lungs and and nasal passages are. I hope my body is still okay and hope everyone (my cells) doing their best everyday
Our commensal bacteria and mucous help to protect our respiratory passages …
Yeah imagine additionally clogging our passageways with some diaper because someone somewhere said so.
Thanks for this video, I find it helpful.
More effective than I figured
Can you look at the UV-C LED filtering of a LARQ water bottle?
this is extremely interesting thank you
COVID: "Do you FEEL safe?"
*Cloth Mask has left the chat*
I didn’t see any virus or bacteria caught in microscope therefore it seems like a proof of being ineffective - if you look at mere size of viruses it is like a mosquito going through a chain link fence
Love your channel and content. As a nurse who has worked through the thick of COVID the last 3 years, on a COVID unit, and wearing the N-95 masks for hours long each shift, I can attest to it's ability to protect the wearer. Long story short, I was the first to a code blue situation for a covid patient wearing only a surgical mask (in times of crisis, sometimes we tend to forget about ourselves and focus on the person in need) and had began CPR. Minutes later when I was relieved, fellow colleagues mentioned to me that I need to put my N95 on in which I did but didn't think nothing of it after the event. 3 days later, I tested positive had a terrible 2 week long recovery. Luckily, I didn't have to be hospitalized or deal with any major complications, but the fact that I knew what covid does to people had me worried and thinking about it every single day until I recovered.
Masks do work. We are in a recovery time, but it's not time to get complacent. Stay safe all.
great to see videos about stuff like this that people actually use day-to-day.
My mom has already washed my N95 marks more than 30+ times, and still it is working and protecting me from corona virus😂
awesome vídeo
There’s something about that background music that is very annoying
