In the study cited HEPA filters did not appear to be effective in kindergartens where kids played closely together. That doesn’t mean that HEPA filters don’t have utility in other scenarios such as a doctor’s or dentist’s offices. I would like to see a study in which one kindergarten opens the windows periodically and another one doesn’t.
@@Mae-vq1duyep in my area the doctors that had their patients outside getting fresh air stayed out of the hospital during the worst of the pandemic. Even our critical care doctor and infectious disease doctor recommended it to the staff to help them stay healthy. Even when they both got covid they were outside in their yards during the day not locked in a room at home.
@@Mae-vq1du I was a teacher for a number of years and when, post-COVID, I insisted on keeping a breeze going through the classroom at all times, it was my first year of teaching without catching a cold.
Also, the point is not to prevent reinfection in all of the kids, most of whom have had Covid multiple times with no issues. The point with HEPA filters is so that those who are immunocompromized, will be able to protect themselves. Most who are in that situation already use N95 masks, but in the long run HEPA filters are needed as well, because the masks aren't fully protective.
When my daughter was in med school, one of the pediatric instructors said that if you have toddlers, you should assume that everything in your house is covered in a thin film of feces. And act accordingly.
OR….we could just let kids back outside. Keeping them locked up all day has negative mental implications for young children, especially boys, as it is, and I don’t think it’s good for their physical health either. When I was a kid, we got recess and outdoor PE, and we weren’t sick like kids today are. I’m sure there are many factors at play here (pun very much intended), but locking kids in classrooms for 8 hours a day, with no fresh air, has to be one of them.
Disabling outdoor play areas, or more generally, outdoor *recreation* areas serving all ages, was one of the truly remarkable stupidities of the COVID era.
I've found (anecdotally) that HEPA filters do wonders for my _allergies._ I've worked in schools for 35 years, and of course attended school. I hate the newer buildings! There are school districts that don't get into updating as much, so they'll still have the high ceilings and transom windows that act as natural air conditioning. They also aren't as dusty, believe it or not. But you get in the newer buildings, or the ones that were updated to lower the ceilings and close off the transoms, and it's itchy eyes all day for me. HEPA filters do help with that, as do good air purifiers. But none of that has cut down on any contagious sicknesses. Stuff is going to go around. Better to spend money on strengthening the immune system through better nutrition and exercise in fresh air.

As an HVAC technician the sheer amount of indoor air quality products that people wanted installed during Covid was staggering. Previously outside of medical facilities or clean rooms I have not seen many HEPA filtration systems. It was odd seeing celebrities Robert Deniro, Lady Gaga and J.lo pushing a Well Health Safety certification (eye roll). Most of the protocols they suggested were already in place building codes displayed to a non familiar public. It was interesting to see people and organizations demand IAQ products after removing a filter from last year. It appears the fad is over because the uv bulbs have a service life of two years and people are not opting to replace them.
"Most of the protocols they suggested were already in place building codes displayed to a non familiar public. " But do most old buildings (like 15+ years old) actually follow those codes?
@@mka6245 Yes, people have known fresh air has been a good thing for quite sometime now. Number of air exchanges per hour, down to the rooms function has been regulated for quite some time.
Our local school district spent $$$ buying every classroom one of those filtration systems. Terrible waste of money, but it does cut down on the bad stench these children emit.
Also, ambient and indoor air pollution and allergens are reduced with HEPA, all of which have better RCT evidence for efficacy, so the combined benefit needs to be considered.

Fascinating. I use to teach 1st grade and one year we had a little girl with cancer so we had a portable air filter and I always swore that was the healthiest year I ever taught. But we did a ton of Clorox wipes throughout the day and the parents had a big buy in to not let their kids come to school sick so there were many factors probably.
improving ventilation is not adding hepa filters...I do think hepa filters are a nice addition to good ventilation, which is circulating out indoor air filled with CO2 and various toxins with freshly, naturally filtered air with O2 from plants and trees
We can have a good guess what happens when kids don’t get respiratory viruses at all. In the early part of the pandemic, here in California, we saws almost zero ear infections, almost no RSV, rare influenza, etc. From summer of 2022 until now, we’ve had the worst respiratory virus seasons that I can recall in 45 years of medicine. Flu and RSV started very early and were more severe, especially RSV (which we all get every few years). Did everyone’s T-cells wane? I don’t know, but parents are asking why their child is getting so sick, so often.
Speculation on coronavirus dispersion: Viruses inhabit the moisture droplets that are coughed out of human beings. These droplets vary in size between about 0.5 - 5.4 microns. The filtration of HEPA is 0.3 microns, which is smaller than these moisture droplets, suggesting some effectiveness. However, the virus remains viable or infectious for 1 -5 days. Now, the problem could easily be that the moisture simply evaporates due to normal air flow thru HVAC systems, and this evaporation eventually frees the viral particles from the HEPA filter because the maximum size of a coronavirus is ABOUT 140 NANOMETERS - - Which is orders of magnitude smaller than the practical filtration capability of any HEPA filter or any inexpensive mask! This could create an unusual effect: the filter stops nearly all droplets generated by human respiration, but then then all those droplets evaporate and those nanometer-size coronaviruses are freed and blown into whatever environment they travel to, during which time they remain suspended airborne, investing the environment, completely invisible, viable and infectious to some degree - maybe hours to days.
I think they should have also done a study in an office building with adults. I used to substitute in kindergarten- of course a hepa filter isn’t going to work, kids have no sense of personal space and are always on top of each other. I love little kids but They are germ factories. 😂
Thanks for the reporting, Vinay. Always solid, professional, and caring. So enriching listening to a thinking Doctor, even if I don't always agree with your conclusions. By the way, looking pretty sharp too. I like the haircut.
ULPA filters theoretically filter out 99.9% of particulate matter that is smaller than the size of any virus. The problem is they are quadruple the cost of HEPA filters and clog faster than HEPA necessitating more frequent filter changes. They also require more powerful and energy hogging blower fans.
Didn't the big government masking study, that had it's problems, come to the conclusion that masks didn't work but Ventilation did. It's interesting to note the difference between ventilation, of which being outside would be 100%, and HEPA filters.
As an infection control nurse. In the United States CDC certified. I can assure you that mask use even by train personnel is sketchy at best. Auto contamination that is contaminating yourself through improper donning and doffing of the PPE leads to huge amounts of self-contamination. One need look no further than the guy out on the corner wearing a mask reaching up pulling it down below his nose and then a week later he has a virus. Why would this happen if you don't know you don't have the clinical or critical thinking skills to understand why masks fail. The other issue was that the equivalent of a surgical mask and a room full of COVID-19 was like throwing sand through a chain link fence. If you don't understand that you don't have the ability to do infection control properly. My team that we built kept a California CRC in the skilled areas covid-free for 19 months. Proper screening proper eradication of viral particles proper PPE use and the all hands on deck method we implemented meant that as the infection preventionist for the facility everyone who walked in the building was part of the infection control team they were educated on this and they all visitors family members staff ancillary staff administrators and everyone bought in to the program It included hydroxyl generators to remove airborne viral particles the way we have always done it. With light that is why you need to go outside. New studies say 30 minutes of direct sunlight if you have been infected with COVID-19. Remember all the talk about vitamin d levels. It turns out the people who gleaned the most benefit were those who had acquired their vitamin d naturally through food products and direct sunlight preferably more than 30 minutes a day. There are several studies being done on the exposure of light. I would like to take you back to pre-1946. How did we handle respiratory viruses prior to that year. We used a model that had balconies outside of patient's rooms large enough for all of the rooms in the wards to be pushed out to the balconies. We did this for tuberculosis/consumption. We have done it for many other illnesses as well This is what we did before we had antibiotics or antivirals. My final point is I'm going to ask the doctor here a serious question how many successful vaccines against the common cold do we have today. The answer is zero The reason why is coronaviruses mutate so fast and the key point of their mutation is to avoid immunity. Even if you had a variant only two variants ago of a common cold odds are if exposed in a significant amount you will catch the next cold. Many people believe alls we have witnessed during COVID-19 is the birth of a new cold virus. I heard this from a Japanese epidemiologist the very first few months of COVID-19. If you look at history viruses of this type have always mutated in the same direction. I have confirmed this with AI models these viruses always become more contagious and less virulent The idea of the virus is to live indefinitely within our population and have ample hosts to do so it must not kill its host. This is a symbiotic relationship in development with a virus. Yes we may get it Yes we may get a little sick odds are only the very vulnerable will die. And the downfall the vaccine has major health side effects that must be addressed we have witnessed the largest clinical trial in the history of mankind. We gave an unproven untested vaccine access to a huge portion of the population. I am against universal vaccination simply for the fact that if the vaccine has major side effects you basically have exposed the entire population to those side effects Will everyone get them probably not Will it kill people unnecessarily probably show and probably has. We have studied in depth as typical the male response to the cardiac issues known to both the virus and the vaccine. What we have not looked at closely is the number of females who have suffered what was used to be called broken heart syndrome after they were vaccinated usually after the booster dose. The accumulation of the vaccine proved no benefit. It is 3 weeks after I took my booster shot after already having COVID wants got it again. So I have had the novel strain vaccinated twice took a booster got BA-5 and then this Christmas just for fun got JN.1. I don't know how many of you will even comprehend what I am saying here. I am tired I'm tired of the fight I'm tired of telling people things work that do not I am tired of being guided around by a nose ring by Big pharma Center for Medicaid services the DHS the CDC NIH and anyone else who made a profit just like the men this doctor is talking about who sold HEPA systems thinking they worked as well. While they did capture particles they required it always to be disinfected almost immediately to eliminate spread. There was so many things we did wrong. During this pandemic many of them cost lives. But none no more so than the governor of New York sending COVID-19 patients with pre Delta variants back to nursing homes that had no isolation rooms. Basically at that time the virus killed lots of people per number of people infected unlike today. It is important to note that in doing so the governor of New York at the time Cuomo killed thousands if not tens of thousands of elder people are grandmothers are grandfathers are great grandmothers and great grandfathers are moms our dads and if we are old enough ourselves as well. When we let bureaucrats make decisions over health care that they do not comprehend in any way because they have no science background no training no understanding of transmission just like many of the doctors in the world today they do not do that on a daily basis. You're only an expert if you practice what you were doing all the time. As we all know Dr fauci who made huge amounts of decisions for all of us hasn't actually taken care of anyone with COVID other than himself. With his vast knowledge why was it that he could not stay away even though he was not treating people who had it. The answer is obvious the virus became extremely contagious and it has evolved to where it is now the most contagious variant we have ever seen. Also the less deadly variant we have ever seen. There will be people who disagree with my viewpoint. But I no longer care. I will not be a puppet for big pharma big medicine or the government. Even if that means I am retiring as of today. I'm good at what I do because I think critically and because I listened to those who trained me. Because they knew what they knew and the practices that I utilize to keep the facility clean for 19 months we're not the new COVID guidelines we were given but instead I utilized the influenza guidelines that we had used for the last 25 years. You come and you stay with the horse that brought you. Switching successful methods of infection control because you're in a panic is
Thank you for your very thoughtful post. I was a hospital pharmacist for most of my 40- year career, and I'm so glad I retired before all this began. I thought I'd never see real science thrown out the window by Fauci, the covid czar, and all the government incompetence. I myself no longer trust the FDA, CDC, or any of these clowns. Big pharma made billions of dollars on the backs of vulnerable Americans. "Studies? Who needs studies, just believe what we're telling you", they all said. Like always, follow the money trail. Whenever health care is mixed with politicians, you're going to end up with more politics than care.
@@kathya1956 Comment as you want. It’s a public forum. Dr Prasad is against censorship/silencing or unfair judgement. It’s what caused a lot of damage in last few yrs. Scroll over, scan thru longer comments or don’t read them.
Maybe I'm misunderstanding something, but are you saying they studied HEPA filters in different rooms but in the same school building? That seems like an obviously poor study design. The HEPA filter should be installed in the *building* HVAC system (And it shouldn't cost $100k, lol).
Speaking of the HEPA filters I’m very curious if the “air purifiers” really work at our homes? In my community in Poland people got crazy about having a stand by air filter but do they really work?
To various degrees. My ionic filters are great for dust and black mold spores *a big problem here. A few airborne viruses might get knocked down by accident but it's my expectation. I just keep the cleanest house I can 😢😂
If you desire to render colds, influenza, CO^ID or other seasonal infection infrequent, the first step is to be replete in vitamin D. Replete meaning at or above 50 ng/mL in 25 OH vitamin, IMO. YMMV. Nor is that the only step.
Hepa filters are just like patented drugs, you depend on them, but the ongoing high cost will go on forever. Replacement HEPA filters are very expensive, and they take much more electrical power to pull the air thru. The cost of replacing and operating HEPA filters is 10-20X simply using common air/furnace filters. HEPA filters are necessary in some applications, but they are just too expensive for most.
The HEPA filter advocates don't even do basic mechanistic studies, much less observational studies, much less RCTs. They'll intentionally put the HEPA filter in a very small enclosure with 1/100th the volume to clean, insert a one-time dose of smoke, and then show that it can clear up that enclosure. What they should have to show is that in an actual full size room/enclosure, they can clean it with a continuous insertion of smoke because contageous patients continue to breathe and emit the entire time they're in the room. FYI, kids are already well-fed in school with at least free lunches. Schools are already very well funded and they keep getting increased funding while the schools scream they are getting reduced funding every year.
I would hypothesize that air filtration in schools would actually do something for student illness/absenses, mostly because of mold and environmental allergens.
My son after finishing his degree started work on a cruise ship, starting in Singapore, right at the beginning, the ship turned around towards Italy. 4000 on the ship, i said to him... Get outside in the sea air... He got sick for a day and then had to endure being locked up for 3 weeks in Italy before being locked up for 3 weeks in South Africa. Get out of closed up buildings...
Are you serious? He looked so intimidating with the long hair and facial hair. Now he looks like he’s bound for the choir. I guess that’s not such a bad look.
Is there a study about a benefit to controlling allergens (ragweed pollen, dust, cats) with hepa filters, to guard the immune system (weakened or altered due to auto immunity meds) against viral or bacterial infections? I know this is complex, but asking for a friend with hepa filters who gets sick a lot. 😊
Too bad I didn't hear anything but hepa. We've known an d can prove the ultraviolet filters in building do reduce exposures to a multitude of contaminates. Including mold, flu viruses, rhino viruses. Etc . That both infection rates and absenteeism are much reduced. Hepa relies on the size and maintenance of the filter system.
But the children and care takers where also socialising and meeting people outside of kindergarten. They could have gotten infected outside of kindergarten. To proof that HEPA filters work one would have to spend the majority of time during the study in a filtered air environment and maybe have a few people come and go who are exposed to the outside world.
is there a way to make a medical law to mandate surgical masks to practicing surgeons and ppl in the OR room and no one else. plain and simple. is that feasible to accomplish?
The issue I have with Vinay Prasad's take on this study, is that I think he misunderstands the point of Hepa filtration in schools, health care settings, and other public spaces. The point is not to prevent a kid who's had Covid 3 times with no issues to be reinfected a 4th time, the point is that those who wish to protect themselves, due to being immunocompromised or having Long Covid, will be able to. One-way masking in public spaces provides some protection, but without clean air quality it doens't protect fully. With Hepa filtration+masks, they are much safer.
There is an industrial hygienist, I think he's from Ohio, who has made a strong case *for* good air filtering, saying it's what they have to do in factories to protect workers from all kinds of hazards including fine particles of various harmful kinds, industrial solvents, etc. I have lost my records that included the man's name. Obviously a person like that would desire to be paid for his work, but that doesn't rule out the possibility that his recommendations are valid. Maybe someone here can find better info on this person and/or the applicability of industrial hygiene to respiratory viruses than I have these days.
Great study. I appreciate your work. I enjoy your videos and appreciate that you are following the science. I do take issue with the notion that Covid is just a cold or flu. It has shown to be a vascular illness, that can cause long term damage. I am really concerned with how you downplay COVID’s impact on people in general. I have such mixed feelings when a new video of yours appears. On one hand I want to hear what you have to say because you are doing the research but I am concerned with your glossing over the impact Covid has.
Well, this time you acknowledged the field of building ventilation (thanks) but then you promptly claimed a fieldwide conflict of interest (among academic researchers with government funding??) and claimed that HEPA filters were the answer put forth by the field. I have been to several building ventilation conferences and got my PhD in a related area. Not once did I hear a paper on HEPA filtration as the answer to sick building syndrome. It was rather about efficient ways to increase ACH - air changes per hour. The common benchmark statistic in the field was that the air quality on a typical American highway was healthier and safer for people than the air quality in most buildings. The big concerns/efforts in the field when I graduated were: -too little natural ventilation, causing buildup of mold and other contaminants and toxins -off-gassing from synthetic materials and paint, etc in buildings - toxins in existing ventilation systems (eg asbestos and dust/pollen), difficulty cleaning them, and how filters were a recipe for disaster because they harbor biological concerns (like mold) - how to make outdoor air treatment for pumping fresh air into buildings more energy efficient - what the optimal ACH was for various activities to prevent SBS and for productivity. I was one of these experts calling for a focus on building ventilation, and not once did I claim HEPA filters were the answer. I rather suggested the common sense study of how many ACH a restaurant or venue would need for a certain number of people in order to reduce rates of covid. In fact, I had studied big box stores, and knew about airplane, both locations are known for relatively high ACH - and relatively low covid transmission rates. You know that covid is rarely transmitted outdoors. What the real experts in the field were recommending was to make indoor air more like outdoor air. Incidentally, that's exactly what they did during the flu outbreak last century - in cities like Boston and NYC they mandated heating systems that would ensure a comfortable temperature in the apartment if the windows were open in winter time. And I cannot stress enough that the evidence on a lack of fresh air in buildings correlates to one of the biggest drops in performance you could possibly see, whether in office work or among school children. You cannot minimize the role of fresh air in educational outcomes!
We need to teach researchers to let the quality of their research speak and not feel the need to conclude the study by talking out of their ass on things that they didn’t investigate. The perfunctory call to keep masking doesn’t appease anyone and just feeds some kind of odd need to smooth over ruffled feathers. The study is on hepa filters. Their conclusions should focus on hepa filters alone.
And we need to be very sure that it is such a good idea to decrease exposure to the common bugs in kindergarten children. This is the age when they come home with green, yellow, white snot, pink eye, ear aches, etc., etc., several times a year. That's the way it's always been - maybe mother nature has her own way of training the immune system and I don't think we can improve on that but I am sure we can make very big mistakes.
Technologies work if you design them properly, I.e. you must address safety at the breathing zone. Air columns in any environment must be properly designed in HVAC to target this factor. Do this and your HEPA filter and all other technologies you wish to use against COVID will show positive results. Just adding a filter to an HVAC system will not help anyone.
Watching your videos just makes me wanna tell everyone told you so! I always thought most of this crap we were doing during the pandemic was useless and more Americans needed to do the simple things like loose weight , eat better, and exercise. I am also in the SF area where we had the worst of the restrictions.
The more I hear about ‘interventions’ by ‘experts’, the less likely I am to listen. And the more obvious it is that common sense and the natural world has more to ‘teach’ us, if only we’d listen…
I used a full-coverage painting mask with a separate filter that strapped to my waist: Shear Cosplay of course. (But so are the cloth masks!) but with carbon element at least I didn't have to smell the fear off the sheeple 😂 they only way to prevent airborne viruses is with a fully pressurized suit fed from a liquid air supply. Kinda heavy a quick trip to the store. I watched closely and really didn't think the disease justified that level of protection or any at all really. I worked a few years in clean labs 😊
But, but, the DROPLETS!!! 😂 Six feet is the magic distance! Anyone, everyone could pass a virus even without symptoms!Cover your face with a splash guard! 😂
A carbon element added to your regular air filter will do that I use them in my cars cabin air filter so as not to have to smell the gasoline fumes and most of all the homeless crowding into the street 😢😂
Did you read the study? They compared well ventilated rooms without purifiers to poorly ventilated rooms with them. The conclusion you jump to is not supported 🙄
It is obvious, they should have been wearing three face masks. Folks, this is tongue in cheek BTW, when our grandchildren were in kindergarten, they wore mask. The kids would exchange mask due to liking what the other kid was wearing.
Interesting. Were the children in the Control or Test group wearing masks? I ask because I think little children wearing a mask probably increases their infection risk
I understand that this is focusing on false claims around covid19 protocols However Don't hepa filters help eliminate molds, some bacteria, and other particulates in public areas? Would that not be beneficial?
@@mahnamahna3252 LOL excellent argument. Why do you think he claimed this study proved they are "total waste" of money if it didn't even explore other possible benefits?
@BDnevernind I don't think it's because he doesn't care about children I think it's because of constant betrayal from those who we've handed power over to in numerous ways who waste our money, profit off of our fear and complacency, and continuously attempt to silence/slander people who oppose them. Some emotional intelligence and familiarity ought be utilized before we make hyperbolic statements about another person's motivation.
@@mahnamahna3252 So his hyperbole in a produced video about scientific facts not in evidence is warranted, and my hyperbole about children not being his actual focus in a video that is mostly about how right he was all along, not warranted. Got it.
Kindergarten is a German word. Kindergarten is a compilation between kinder which translates to children and garten which translates to garden. It literally means "GARDEN OF CHILDREN" sounds creepy doesn't it. Would be a good title for a horror movie.
Yes Patrickf.234. They're not filters. Hospitals use a bank of lights to sanitize a room and yes they work. However, there are wands sold by Amazon. Don't waste your money as the lights are too weak to kill germs. The drawbacks with UV light is exposure to skin or eyes. You can get burned.
@@richardscathouse In context, that really doesn't matter. When exposed to UV-C virii fall apart which renders them harmless. Using terminology that's applicable to other infectious agents really isn't confusing anyone, so why shout about it here?
so, in review: surgical masks dont work n95s dont work hepa filters dont work respiratory viruses are part of life; our best technologies cannot stop them at scale. I think i'm gonna go fully encapsulated hazmat. anyone know where ii can get some scuba tanks? the hilarious part is my good work friend Hector (miss ya buddy) and i were having conversations about this is Jan 2020 because we had both served in the military and anyone who has had to protect from NBC warfare (that is to say every person who has ever served in the military - even the biggest imbeciles who barely qualified to enlist) understands this perfectly well

Allergens are not coming from the respiratory tract of your co-workers or others in the room.

i could have told u that from logic. if u have toxic gas in a room u cant just filter it out if everyone is constantly making more.

But we did a ton of Clorox wipes throughout the day and the parents had a big buy in to not let their kids come to school sick so there were many factors probably.
When we all got covid. Put a filter in the living room and that's where my nephew slept. He didn't get sick.
Snake oil comes in a dazzling array of types and flavors these days.
Indeed so. 😂 and no shortage of salesman are about 😢
Have the kids go outside and get some sunshine and exercise and stay off their smart phones for an hour a day.
improving ventilation is not adding hepa filters...I do think hepa filters are a nice addition to good ventilation, which is circulating out indoor air filled with CO2 and various toxins with freshly, naturally filtered air with O2 from plants and trees
We can have a good guess what happens when kids don’t get respiratory viruses at all. In the early part of the pandemic, here in California, we saws almost zero ear infections, almost no RSV, rare influenza, etc. From summer of 2022 until now, we’ve had the worst respiratory virus seasons that I can recall in 45 years of medicine. Flu and RSV started very early and were more severe, especially RSV (which we all get every few years). Did everyone’s T-cells wane? I don’t know, but parents are asking why their child is getting so sick, so often.
Same with the adults. We have been running about 35 patients in my adult unit and about half of them are influenza and RSV. It is bad this season.
Fresh air ventilation is probably the best way to air things out.
Speculation on coronavirus dispersion: Viruses inhabit the moisture droplets that are coughed out of human beings. These droplets vary in size between about 0.5 - 5.4 microns. The filtration of HEPA is 0.3 microns, which is smaller than these moisture droplets, suggesting some effectiveness. However, the virus remains viable or infectious for 1 -5 days. Now, the problem could easily be that the moisture simply evaporates due to normal air flow thru HVAC systems, and this evaporation eventually frees the viral particles from the HEPA filter because the maximum size of a coronavirus is ABOUT 140 NANOMETERS - - Which is orders of magnitude smaller than the practical filtration capability of any HEPA filter or any inexpensive mask! This could create an unusual effect: the filter stops nearly all droplets generated by human respiration, but then then all those droplets evaporate and those nanometer-size coronaviruses are freed and blown into whatever environment they travel to, during which time they remain suspended airborne, investing the environment, completely invisible, viable and infectious to some degree - maybe hours to days.
I think they should have also done a study in an office building with adults. I used to substitute in kindergarten- of course a hepa filter isn’t going to work, kids have no sense of personal space and are always on top of each other. I love little kids but They are germ factories. 😂
I had a fan at my desk with a simple ionic filter and a grill that could turn ozone from the computer to oxygen. It worked out quite well 😅
It’s the air they breathe via filtration so it doesn’t matter if they are close together.
I think we are failing to consider the most important point that they do remove the fart smell 😂
I'm gonna need an RCT for that. 😂
@@erikaoliver2591taking participant sign ups now. I’ll fire up the HEPA filter under my desk 😂
Our school district just spent $30M on updating HVAC after a dramatic speech in BOE meeting and she went on to become a board member.
Thanks for the reporting, Vinay. Always solid, professional, and caring. So enriching listening to a thinking Doctor, even if I don't always agree with your conclusions. By the way, looking pretty sharp too. I like the haircut.
But HEPA filters make me feel clean - it's all about the feelings. The quality of the science doesn't make much difference.
Not anymore. Thanks Dr Fauci 😢😂
ULPA filters theoretically filter out 99.9% of particulate matter that is smaller than the size of any virus. The problem is they are quadruple the cost of HEPA filters and clog faster than HEPA necessitating more frequent filter changes. They also require more powerful and energy hogging blower fans.
Didn't the big government masking study, that had it's problems, come to the conclusion that masks didn't work but Ventilation did. It's interesting to note the difference between ventilation, of which being outside would be 100%, and HEPA filters.
As an infection control nurse. In the United States CDC certified. I can assure you that mask use even by train personnel is sketchy at best. Auto contamination that is contaminating yourself through improper donning and doffing of the PPE leads to huge amounts of self-contamination. One need look no further than the guy out on the corner wearing a mask reaching up pulling it down below his nose and then a week later he has a virus. Why would this happen if you don't know you don't have the clinical or critical thinking skills to understand why masks fail. The other issue was that the equivalent of a surgical mask and a room full of COVID-19 was like throwing sand through a chain link fence. If you don't understand that you don't have the ability to do infection control properly. My team that we built kept a California CRC in the skilled areas covid-free for 19 months. Proper screening proper eradication of viral particles proper PPE use and the all hands on deck method we implemented meant that as the infection preventionist for the facility everyone who walked in the building was part of the infection control team they were educated on this and they all visitors family members staff ancillary staff administrators and everyone bought in to the program It included hydroxyl generators to remove airborne viral particles the way we have always done it. With light that is why you need to go outside. New studies say 30 minutes of direct sunlight if you have been infected with COVID-19. Remember all the talk about vitamin d levels. It turns out the people who gleaned the most benefit were those who had acquired their vitamin d naturally through food products and direct sunlight preferably more than 30 minutes a day. There are several studies being done on the exposure of light. I would like to take you back to pre-1946. How did we handle respiratory viruses prior to that year. We used a model that had balconies outside of patient's rooms large enough for all of the rooms in the wards to be pushed out to the balconies. We did this for tuberculosis/consumption. We have done it for many other illnesses as well This is what we did before we had antibiotics or antivirals.
My final point is I'm going to ask the doctor here a serious question how many successful vaccines against the common cold do we have today. The answer is zero The reason why is coronaviruses mutate so fast and the key point of their mutation is to avoid immunity. Even if you had a variant only two variants ago of a common cold odds are if exposed in a significant amount you will catch the next cold. Many people believe alls we have witnessed during COVID-19 is the birth of a new cold virus. I heard this from a Japanese epidemiologist the very first few months of COVID-19. If you look at history viruses of this type have always mutated in the same direction. I have confirmed this with AI models these viruses always become more contagious and less virulent The idea of the virus is to live indefinitely within our population and have ample hosts to do so it must not kill its host. This is a symbiotic relationship in development with a virus. Yes we may get it Yes we may get a little sick odds are only the very vulnerable will die. And the downfall the vaccine has major health side effects that must be addressed we have witnessed the largest clinical trial in the history of mankind. We gave an unproven untested vaccine access to a huge portion of the population. I am against universal vaccination simply for the fact that if the vaccine has major side effects you basically have exposed the entire population to those side effects Will everyone get them probably not Will it kill people unnecessarily probably show and probably has. We have studied in depth as typical the male response to the cardiac issues known to both the virus and the vaccine.
What we have not looked at closely is the number of females who have suffered what was used to be called broken heart syndrome after they were vaccinated usually after the booster dose. The accumulation of the vaccine proved no benefit. It is 3 weeks after I took my booster shot after already having COVID wants got it again. So I have had the novel strain vaccinated twice took a booster got BA-5 and then this Christmas just for fun got JN.1. I don't know how many of you will even comprehend what I am saying here. I am tired I'm tired of the fight I'm tired of telling people things work that do not I am tired of being guided around by a nose ring by Big pharma Center for Medicaid services the DHS the CDC NIH and anyone else who made a profit just like the men this doctor is talking about who sold HEPA systems thinking they worked as well. While they did capture particles they required it always to be disinfected almost immediately to eliminate spread. There was so many things we did wrong. During this pandemic many of them cost lives. But none no more so than the governor of New York sending COVID-19 patients with pre Delta variants back to nursing homes that had no isolation rooms. Basically at that time the virus killed lots of people per number of people infected unlike today. It is important to note that in doing so the governor of New York at the time Cuomo killed thousands if not tens of thousands of elder people are grandmothers are grandfathers are great grandmothers and great grandfathers are moms our dads and if we are old enough ourselves as well. When we let bureaucrats make decisions over health care that they do not comprehend in any way because they have no science background no training no understanding of transmission just like many of the doctors in the world today they do not do that on a daily basis. You're only an expert if you practice what you were doing all the time. As we all know Dr fauci who made huge amounts of decisions for all of us hasn't actually taken care of anyone with COVID other than himself. With his vast knowledge why was it that he could not stay away even though he was not treating people who had it. The answer is obvious the virus became extremely contagious and it has evolved to where it is now the most contagious variant we have ever seen. Also the less deadly variant we have ever seen. There will be people who disagree with my viewpoint. But I no longer care. I will not be a puppet for big pharma big medicine or the government. Even if that means I am retiring as of today. I'm good at what I do because I think critically and because I listened to those who trained me. Because they knew what they knew and the practices that I utilize to keep the facility clean for 19 months we're not the new COVID guidelines we were given but instead I utilized the influenza guidelines that we had used for the last 25 years. You come and you stay with the horse that brought you. Switching successful methods of infection control because you're in a panic is
Thank you for your very thoughtful post. I was a hospital pharmacist for most of my 40- year career, and I'm so glad I retired before all this began. I thought I'd never see real science thrown out the window by Fauci, the covid czar, and all the government incompetence. I myself no longer trust the FDA, CDC, or any of these clowns. Big pharma made billions of dollars on the backs of vulnerable Americans. "Studies? Who needs studies, just believe what we're telling you", they all said. Like always, follow the money trail. Whenever health care is mixed with politicians, you're going to end up with more politics than care.
We’re beyond reading very long responses. Get to the point.

Thank you for this very concise lesson. .if we but only need people like you.
Maybe I'm misunderstanding something, but are you saying they studied HEPA filters in different rooms but in the same school building? That seems like an obviously poor study design. The HEPA filter should be installed in the *building* HVAC system (And it shouldn't cost $100k, lol).
Not saying that would give better efficacy, but doing a single room in a larger environment is obviously a poor choice to assess this.
Speaking of the HEPA filters I’m very curious if the “air purifiers” really work at our homes? In my community in Poland people got crazy about having a stand by air filter but do they really work?
To various degrees. My ionic filters are great for dust and black mold spores *a big problem here. A few airborne viruses might get knocked down by accident but it's my expectation. I just keep the cleanest house I can 😢😂
I'm reading in an old 1959 " Doctor in the House" opening up the windows to get fresh air. Have we become stupid?
We haven't got any of that any more. Fresh air now needs to be made, you can't just open a window and get it for free.
well spoken, thanks
If you desire to render colds, influenza, CO^ID or other seasonal infection infrequent, the first step is to be replete in vitamin D. Replete meaning at or above 50 ng/mL in 25 OH vitamin, IMO. YMMV. Nor is that the only step.
Hepa filters are just like patented drugs, you depend on them, but the ongoing high cost will go on forever. Replacement HEPA filters are very expensive, and they take much more electrical power to pull the air thru. The cost of replacing and operating HEPA filters is 10-20X simply using common air/furnace filters. HEPA filters are necessary in some applications, but they are just too expensive for most.
The HEPA filter advocates don't even do basic mechanistic studies, much less observational studies, much less RCTs. They'll intentionally put the HEPA filter in a very small enclosure with 1/100th the volume to clean, insert a one-time dose of smoke, and then show that it can clear up that enclosure. What they should have to show is that in an actual full size room/enclosure, they can clean it with a continuous insertion of smoke because contageous patients continue to breathe and emit the entire time they're in the room.
FYI, kids are already well-fed in school with at least free lunches. Schools are already very well funded and they keep getting increased funding while the schools scream they are getting reduced funding every year.
Most smoke particles are 1000x of times larger than viruses. Never bet against intentional ignorance 😢

I would hypothesize that air filtration in schools would actually do something for student illness/absenses, mostly because of mold and environmental allergens.

Is there a study about a benefit to controlling allergens (ragweed pollen, dust, cats) with hepa filters, to guard the immune system (weakened or altered due to auto immunity meds) against viral or bacterial infections? I know this is complex, but asking for a friend with hepa filters who gets sick a lot. 😊
Are you aware that the FDA has ruled thatinformed consent is not necessary for low risk clinical interventions, and can you comment on this, Vinay?
The world went insane in 2020. If (/WHEN) we get an actual seriously dangerous-to-kids respiratory pandemic it is going to be absolute chaos.
World is fine. Democrats and liberals went insane and ain’t ever coming back
Hooo boy. It's a good thing you weren't around for the Black Death or the Spanish Inqusition. 🤕🙄😢
"Quasi Experimental?" 12 minutes and no examples, how the filter placed.
air exchange would be a better test
Too bad I didn't hear anything but hepa.
We've known an d can prove the ultraviolet filters in building do reduce exposures to a multitude of contaminates. Including mold, flu viruses, rhino viruses. Etc .
That both infection rates and absenteeism are much reduced.
Hepa relies on the size and maintenance of the filter system.
But the children and care takers where also socialising and meeting people outside of kindergarten. They could have gotten infected outside of kindergarten. To proof that HEPA filters work one would have to spend the majority of time during the study in a filtered air environment and maybe have a few people come and go who are exposed to the outside world.

It might be good for kids with dust or pollen allergies.
is there a way to make a medical law to mandate surgical masks to practicing surgeons and ppl in the OR room and no one else. plain and simple. is that feasible to accomplish?
The issue I have with Vinay Prasad's take on this study, is that I think he misunderstands the point of Hepa filtration in schools, health care settings, and other public spaces. The point is not to prevent a kid who's had Covid 3 times with no issues to be reinfected a 4th time, the point is that those who wish to protect themselves, due to being immunocompromised or having Long Covid, will be able to. One-way masking in public spaces provides some protection, but without clean air quality it doens't protect fully. With Hepa filtration+masks, they are much safer.
There is an industrial hygienist, I think he's from Ohio, who has made a strong case *for* good air filtering, saying it's what they have to do in factories to protect workers from all kinds of hazards including fine particles of various harmful kinds, industrial solvents, etc. I have lost my records that included the man's name. Obviously a person like that would desire to be paid for his work, but that doesn't rule out the possibility that his recommendations are valid. Maybe someone here can find better info on this person and/or the applicability of industrial hygiene to respiratory viruses than I have these days.
Great study. I appreciate your work. I enjoy your videos and appreciate that you are following the science. I do take issue with the notion that Covid is just a cold or flu. It has shown to be a vascular illness, that can cause long term damage. I am really concerned with how you downplay COVID’s impact on people in general. I have such mixed feelings when a new video of yours appears. On one hand I want to hear what you have to say because you are doing the research but I am concerned with your glossing over the impact Covid has.
Well at least it was JOBS during the pandemic .. 😢
Dr please pray for God's protection everyday
Fans and open windows work better.
Well, this time you acknowledged the field of building ventilation (thanks) but then you promptly claimed a fieldwide conflict of interest (among academic researchers with government funding??) and claimed that HEPA filters were the answer put forth by the field.
I have been to several building ventilation conferences and got my PhD in a related area. Not once did I hear a paper on HEPA filtration as the answer to sick building syndrome. It was rather about efficient ways to increase ACH - air changes per hour. The common benchmark statistic in the field was that the air quality on a typical American highway was healthier and safer for people than the air quality in most buildings. The big concerns/efforts in the field when I graduated were:
-too little natural ventilation, causing buildup of mold and other contaminants and toxins
-off-gassing from synthetic materials and paint, etc in buildings
- toxins in existing ventilation systems (eg asbestos and dust/pollen), difficulty cleaning them, and how filters were a recipe for disaster because they harbor biological concerns (like mold)
- how to make outdoor air treatment for pumping fresh air into buildings more energy efficient
- what the optimal ACH was for various activities to prevent SBS and for productivity.
I was one of these experts calling for a focus on building ventilation, and not once did I claim HEPA filters were the answer. I rather suggested the common sense study of how many ACH a restaurant or venue would need for a certain number of people in order to reduce rates of covid. In fact, I had studied big box stores, and knew about airplane, both locations are known for relatively high ACH - and relatively low covid transmission rates.
You know that covid is rarely transmitted outdoors. What the real experts in the field were recommending was to make indoor air more like outdoor air.
Incidentally, that's exactly what they did during the flu outbreak last century - in cities like Boston and NYC they mandated heating systems that would ensure a comfortable temperature in the apartment if the windows were open in winter time.
And I cannot stress enough that the evidence on a lack of fresh air in buildings correlates to one of the biggest drops in performance you could possibly see, whether in office work or among school children. You cannot minimize the role of fresh air in educational outcomes!
We need to teach researchers to let the quality of their research speak and not feel the need to conclude the study by talking out of their ass on things that they didn’t investigate. The perfunctory call to keep masking doesn’t appease anyone and just feeds some kind of odd need to smooth over ruffled feathers. The study is on hepa filters. Their conclusions should focus on hepa filters alone.
And we need to be very sure that it is such a good idea to decrease exposure to the common bugs in kindergarten children. This is the age when they come home with green, yellow, white snot, pink eye, ear aches, etc., etc., several times a year. That's the way it's always been - maybe mother nature has her own way of training the immune system and I don't think we can improve on that but I am sure we can make very big mistakes.
the amount of money schools paid to install these things was insane. millions wasted
*what?! o_0! but i just collected 120k to get HEPA filters for children in Gaza!* well. guess we'll just keep the money. _JC
Technologies work if you design them properly, I.e. you must address safety at the breathing zone. Air columns in any environment must be properly designed in HVAC to target this factor. Do this and your HEPA filter and all other technologies you wish to use against COVID will show positive results. Just adding a filter to an HVAC system will not help anyone.
Remember when the political commentary community was irrelevant?
I was much younger, and faster with my fists! 😊
Watching your videos just makes me wanna tell everyone told you so! I always thought most of this crap we were doing during the pandemic was useless and more Americans needed to do the simple things like loose weight , eat better, and exercise. I am also in the SF area where we had the worst of the restrictions.
The more I hear about ‘interventions’ by ‘experts’, the less likely I am to listen. And the more obvious it is that common sense and the natural world has more to ‘teach’ us, if only we’d listen…
If hepa filters don't work then how the heck do face masks work?
But I cut a hepa filter into a mask and stuck it on my face! 😆
I used a full-coverage painting mask with a separate filter that strapped to my waist:
Shear Cosplay of course. (But so are the cloth masks!) but with carbon element at least I didn't have to smell the fear off the sheeple 😂 they only way to prevent airborne viruses is with a fully pressurized suit fed from a liquid air supply. Kinda heavy a quick trip to the store. I watched closely and really didn't think the disease justified that level of protection or any at all really. I worked a few years in clean labs 😊
But, but, the DROPLETS!!! 😂 Six feet is the magic distance! Anyone, everyone could pass a virus even without symptoms!Cover your face with a splash guard! 😂
link to the paper?
Run an ozone generator during non occupied times. Run on very low level with ventilation during occupation. Ozone kills everything airborne.
It’s 10 meters - reach -
I have to imagine that there are probably still health benefits to having clean air in schools
Man did you succumb to social media….
Air filters do nothing if the problem is the actual kids themselves.
It helps with smell tho!
A carbon element added to your regular air filter will do that I use them in my cars cabin air filter so as not to have to smell the gasoline fumes and most of all the homeless crowding into the street 😢😂
👍
Did you read the study? They compared well ventilated rooms without purifiers to poorly ventilated rooms with them. The conclusion you jump to is not supported 🙄
Yeah but they work great for allergies.
It is obvious, they should have been wearing three face masks. Folks, this is tongue in cheek BTW, when our grandchildren were in kindergarten, they wore mask. The kids would exchange mask due to liking what the other kid was wearing.
Thank you cc
Interesting. Were the children in the Control or Test group wearing masks? I ask because I think little children wearing a mask probably increases their infection risk
The people that think the covid virus is living in the atmosphere because everyone forgot how viruses work.
A little surprising you are not critical of the study for lack of randomization since that is your main critique of other studies
Completely useless?
Sloppy talking.
What about allergens?
A lot of unknowns here.
Of course they don't, airflow is the only thing that will help. Literally blowing the virus away and dispersing its density.
