And this is for whom?
it would be nice to know how to evaluate the quantity of ” layers ” i mean with a very thick fabric, two layers is probably enough (three layers would make it unwearable because too inconfortable to breathe) 😅
the mask isn’t supposed to be suffocatingly warm neither. if you would say things like ” 2 or 3 layers of t-shirt or pillow fabric according to the density of the fabric ”, how can we know if it’s 2 or 3 ? you could give a rule of a thumb for the population using their own d. i. y. mask, that would be great 👍
something like…. ” if you can make the flame of a candle move, when you blow through your mask, it means you need to add another layer ” ?? we need those kind of tips as we make d. i. y. masks, okay ? thanks.
also, don’t you have a pdf document about recommandations for people making d. i. y. masks for professionnals ?? please link it at in the description of the video. that would be helpful. thanks.
You had billions of dollars and two decades to figure this out before 2020. Dr. Tam said they weren’t effective, then supported they were dangerous, and now …? What a blend of corruption and incompetence you are. Defund the UN – they are evil and in the pockets of those who want to destroy free societies.
Restriction of oxygen intake and excess build up of carbon dioxide and the inhalation of micro fibres directly into the lungs which cannot be removed! Why would any sane person wear a stupid face covering???!!?? Criminal

And you non-medical people, please cite the source research on your medical claims. Reading social media is not the same as spending 7 years in med school.
This technology teaching is really needed.
When was it that the W.H.O was tweeting about no human to human transmission? Also the W.H.O tweeted last month that they were sending a team to China . Did that ever happen. 🤷🏾♀️
Thanks you 👍🏻
USE THE MICROSCOPE TO SEE CLEARLY THAT THE HOLES ARE VERY MORE GIGANTIC THAT THE BACTERIAS. THE VIRUSES ARE SMALLER THAN BACTERIAS. USING THE MASKS IS AN VERY IDIOT IDEA. THE MASKS ARE THE PLACE WHERE THE MICROBES PROLIFERATE. Seeing the biyed masks under a students microscope You will see a lot of bacteries, the tubercolosis and the pest included.
Shove your masks where the sun don’t shine !
MASKS DON’T SAVE YOU OR SLOW IT DOWN THAT’S A FACT
MASKS CAN ONLY GIVE SOME PROTECTION IF ITS SPECIALLY FITTED
B.S mask doesn’t change anything and you know it. stop pushing a false pandemic to justify your mistakes.
