according to a controlled study, a hepa filter (13? - "conventional" hepa the author wrote = 13?) will filter sars-cov-2 droplets/aerosols by " 85.38%" in 1 pass/cycle of room air, 96.03% after 2nd pass and >99.97% after the 7th pass - how fast for 1 pass depends the air purifier's power

Absolutely astounding technology. Even more astounding is that neither the WHO nor any government agencies or medical facilities were prepared to even look at installing these BlueSky machines in public spaces, hospitals, airports, hospitals etc! Of course, big Pharma wouldn't have benefitted from safe air to breathe. Makes one think 🤔

Pleasure, thank you for your comment

I didn't hear accurately first time, but suddenly something triggers me. Thank you for your job.

😉 *promo sm*

Wouldn’t it be great if hospitals had these machines!!!!

👌

What an innovative solution

Cool video 👌

Hello, and how about Omicron? Will a Hepa 14 Filter do the job? Greetings:)

Really nice content and presented well. Also like that it was sectioned into parts

the best.!!

Well worth listening to.

It will caught the droplets while they’re moist, what happens when they do dry, released or stuck at that point?

It is aerosol. So, now what? Will it still work?

but what happens when the droplet that's been captured by HEPA filter dries over time? wouldn't that blow virus particles into the air?

What will happen when the aerosol will dry? Would the viruses be loose then?

Cool and how do the filters get changed?

@BlueSky-Global, Dr. Michael Seitz hi, can HEPA filter provide better ventilation from spread of covid 19 airborne? tq

let say the virus is not submerged in mucus or other type of matrix except the air. How significant is the brownian motion effect towards the virus which causes the virus to kind of 'bouncing' around in the air and made its effective radius bigger

When that particle evaporates, the virus particles can then pass into your lungs, the droplet that allowed the virus particles to be captured is now gone. Is this why we change out our masks?

was the beginning scripted... lol

IFD FILTER

Could you please explain then why breath with water content still makes its way through several layers of mask or hepa? Does hepa stop 1 micron particles?

Do mask also capture these droplets? If yes then why wud someone need hepa filter masks so expensive?

I'm curious as to what you think about these new electric masks like the Atmoblue and the LG Puricare mask that both use fans and H13 filters with regards to coronavirus. Would those be an exception to what you are saying here or does your understanding of the particulates and ability to breathe well still apply even though those have fans?

Can virus flout in air individually? without settling on particle?

Great illustration! However you will not be able to prove it since in HEPA integrity testing we are only looking for 0.3 micron. The criteria would be anything below 0.01% of the up stream challenge of the filter. If you are injection 25,000,000 then the allowable particulate amount would be close 2500 ppm at 0.3 micron. The retention rate would be 99.9900. So anything smaller than 0.3 micron has the opportunity to pass through. Filters are rated for 0.3 micron throughout the industry and the iso criteria for testing is the same. We do not have data to back up anything smaller

Just a question, since the BSC have consistent airflow, won't the droplets dry out and release the viral particles?

THIS IS BULLSHIT. I use hepa materials and i breathe just fine. lol

Thank you, doctor, this is very helpful for my research

Maybe you should just be honest about your motives and change your name to Doctor Kevorkian. Not everyone is as ignorant as the folks who believe you (and like your lies) are. ...You are saying that once a liquid droplet carrying a .004 micron virus evaporates on HEPA-filter material, then the .004 micron virus is permanently trapped inside of the filter.

Superb sir As an industrial hygienist Finally my all doubts cleared through your easy explanation

Leaf mask works great...don’t use the N95 filter on the side...the mask create suction when you breath in, creating more sealing on the side...breathing in will take some getting use to...it’s more of a personal convenience compare to the other masks....only cons for me is if you wear glasses...just received my other two mask in case they increase the price

HEPA works, correct. But what happens when the droplet will eventually evaporate? Will HEPA release the lone virus particles into the air? I think this is the place where UV light comes in.

Thank you for this, very simple yet straight to the point discussion about HEPA filter.

I just got it yesterday and upon donning it, the FIT WAS HORRIBLE. THIS IS A BAD PRODUCT< A SCAM. It did not seal on the top and bottom. The straps are extremely flimsy, The area that seals is very scant. I dont' know how this mask can protect you. I leak leakage and a gap at the top of the bridge of the nose, when you conform the mask down, it leaked air on the cheeks, and chin. I've emailed them about a refund and the response is "we are reviewing your request'

Our Meaco air purifier has a UV lamp in it to kill viruses.

I can’t wait to give people covid. Thanks for showing me how to direct my breathing and etc...

The HEPA filters should also have UV-C light. Open areas should have 222 nm ultraviolet light. The most vulnerable should have it in their HVAC systems. Most homes have ultraviolet light in their HVAC already. Nursing homes need at the most. The far UV- C should be in supermarkets, factories, schools, etc.

What's stopping the virus from flying away when the water that suspends it evaporates?

Aaaaaaand the penny drops!!!! I did NOT think of the issue that way and assumed that the virus was smaller than a lot of HEPA filters could capture...

This is actually false, given that the smaller the particle, the higher the removal efficiency for a HEPA filter. This all due in part through the diffusion filtration mechanism. Donaldson Aerospace wrote a good infographic to show the filtration mechanisms at work inside a HEPA filter. “The fact that a HEPA filter’s removal efficiency increases as particle size decreases below 0.3 microns is counter intuitive. However, this is a proven and accepted fact in the filtration sciences.” There is also a section addressing microbes. I would encourage those watching the video to check it out. I also recommend a video that covers some of the filtration mechanisms and also goes over how Brownian motion is the reason as to why small particles are trapped. It also mentions that the diffusion mechanism greatly increases filtration efficiency as particle size reduces. ruclips.net/video/AuVbcvPcjAw/видео.html donaldsonaerospace-defense.com/library/files/documents/pdfs/042665.pdf

About time this is hitting mainstream news!

SHEEPLE BEWARE! Paper & cloth are a breeding-ground for microbes. Each time that you touch your mask you are hand-delivering fungi, bacteria & viruses to a porous/moist breeding-ground. Each time that you inhale you're sucking these pathogenic contaminants through the fibers of your porous/moist mask and into your respiratory tract. A human being exhales 8 ounces of vaporized water each day. Your paper/cloth mask is not a respirator. Science 2020: A virus can be stopped with a dirty swatch of cloth! Science 2020: A virus can be stopped with a dirty piece of paper!

Wow the machine look so clean and slick 👏

Cool soundtrack and the machine looks so cool!
