A quick google search of Bit Chute and what it stands for and the people who post on there quickly tells you that it’s where right wing conspiracy theorists like to hang out, the clue is that they actually tell you that they been removed by YouTube and other hosting sites because of their untruthful posts
When you click on your link to the mask experiment and read the posts below it, you soon see the mindset of the people who watched it, it’s again that small factor of truth that is blown out of all proportion by people who have no idea what they are talking about
Basically the same as Twitter censoring the rubbish Trump spouts out
The gas analysing meter the chap uses is in all probability correct in its readings.
How he interprets the readings and how he conducts the test are what really counts, his test method is flawed and his interpretation of the results are too, if he blew onto the meter without the mask he’d get the same result
A couple of questions are is he qualified to use the meter and does he know what he is doing
The answer to both questions is most likely No, he doesn’t understand the usage of the meter or how to interpret its results
The meter is designed for use in large open rooms if you like to detect levels of gases that would be harmful to health
Below is the answer to your Bit Chute video by Del Bigtree starring his son on AFP Fact Check
“A video shared online aimed to prove that face masks are dangerous to children by showing that toxic levels of CO2 concentrate inside a mask. This is misleading; experts dismissed the experiment as faulty science whose data is the opposite of what should be expected, and said there are no serious health effects to wearing a mask.
“Are you adhering to laws from the government that are hurting the development of your child’s brain?” asked host Del Bigtree in a July 7, 2020 video for his Internet show, The Highwire.
In the video, Bigtree used a carbon dioxide sensor to measure the amount of CO2 in particles per million (ppm) that were concentrated under masks worn by his son. The sensor showed levels of 8,486 ppm with an N95 respirator, 8,934 ppm with a surgical mask, and 9,129 ppm with a cloth mask.
Bigtree compared these findings to a chart from Occupational Health & Safety magazine showing the side effects of working at different CO2 levels.
Although the video was deleted from Bigtree’s YouTube channel for violating the platform’s Community Guidelines, it was watched hundreds of thousands of times and is still available on other platforms.
Face masks -- which an increasing number of state, provincial and local authorities in North America are either requiring or recommending be worn amid the pandemic -- are a contentious issue and have become politicised.
Bigtree is the founder of an anti-vaccine organization, but does not mention any medical or scientific credentials on his website.
Flawed experiment
“They are using the wrong device and they are trying to compare the wrong numbers,” explained Hyo-Jick Choi, a researcher at the University of Alberta, who designed surgical masks and respirator filters that deactivate certain viral strains.
“Their numbers should be the complete opposite,” Choi told AFP by phone, pointing out that in a proper experiment, carbon dioxide levels should be highest with an N95 mask and lowest with a cloth mask, because the latter filters less.
“It’s common sense that a cloth mask will show the lowest filtration efficiency, surgical mask will have a higher filtration efficiency, and the N95 will have the highest efficiency,” Choi said.
He suggested that the findings may be flawed because the sensor used in the video is not suited for the experiment. This carbon dioxide meter from AZ Instrument Corp, a Taiwan based company, ranges from 0 to 2,000 ppm, as the properties read here. Its screen can display readings up to 9,999, but with less accuracy
There is no doubt that wearing a face mask will increase carbon dioxide levels,” Choi conceded. However, the researcher warned that Bigtree’s video misleads by presenting the 5,000 ppm mark as a definite marker of toxicity. Five thousand ppm is the highest recommended exposure for people working eight-hour days every day, particularly in closed spaces.
The experiments further mislead by truncating the chart, making 5,000 ppm look like the highest mark, when in fact the real chart shows that 40,000 ppm and above is the level considered dangerous, even for short periods of time.

Steven Vercammen, a Belgian emergency room physician who wrote a review of studies on carbon dioxide poisoning, also called the experiments in Bigtree’s video “bad science.”
According to Vercammen, the important metric is the oxygen and CO2 levels in the bloodstream.
AFP Fact Check addressed the claim that mask wearing causes hypercapnia, or the buildup of carbon dioxide in the blood, here.
Vercammen told AFP by email that “Occupational safety websites made guidelines for the air concentration in a closed environment, like for workers cleaning silos or other closed environments where CO2 build-up can happen in massive volumes.”
“Numerous experiments have been done that show that there is no significant (health) effect to wearing a mask,” he said.
A study on health care workers exercising with a mask concluded that the N95 mask, “did not impose any important physiological burden during one hour of use”, even though it led to increased carbon dioxide levels. Another study on pregnant women reached similar conclusions. The N95 is a respirator that fits more tightly than a regular mask, and is not recommended for the general population or children during the pandemic, when medical workers have a critical need for them.
Similarly, AFP has examined social media posts falsely claiming that prolonged mask use can cause hypoxia, or a lack of oxygen, CO2 poisoning, or that they violate OSHA minimum oxygen levels.
It’s a good idea to be aware of what a measuring device is actually designed for and be trained in extracting the information the meter is giving you, as pointed out Bigtree does not mention any credentials he has medical or otherwise
Another video was post by another would be Republican politician named Jeff Neff, he’s a firefighter, he tried to do the same sort of test using a different meter, he had responses from the manufacturer of the equipment stating that his experiment was vastly flawed and his results were false
You can search for this to see how his results were blown out of the water

You mention Adolf Hitler in your quest for facts, you really think he was a trustworthy source of information ?
I really hope not
Try this link for size, it shows what wearing a mask really does for gas levels behind a mask
TONY
I feel for you mate, percentages can be useful however they can also have the opposite effect too, it depends how they are interpreted, “damn lies and statistics“ type of thing
I hope the percentages end up well and truly in your favour and are well and truly correct for you, in fact all of our favours
You are right in your situation that you need to be extremely careful, COPD is a nasty disease, I wouldn’t wish it on anyone and I hope that a vaccine will come along for you that can be used by you and all who are in your shoes
Please take care pal
A bit of History
The Spanish flu was so virulent because as pointed out it was the end of WW1 and many troops who contracted it on the European continent brought it back to their home countries and others, surprisingly more American soldiers were killed by the flu than who died in battle
it is said to have infected 500 million people or 1/3 of the worlds population and as said above killed somewhere between 20 and 50 million people, some say it could have been twice that figure due to insufficient medical records due to the lack of medical personnel, if you take the figure of 50 million that is more than the total number of civilians and military people that died in WW1 combined, that is a big percentage in anyone’s language
Interestingly it did not eventuate in Spain, Spain was neutral in WW1 and so could report on all controversial events, Spain actually blamed it on France
They travelled in ships back then and some theories are that the ships became incubators for the flu and once it got out into the general population it spread like wildfire, it’s interesting though that it was not considered to have caused mass deaths in the trenches
it lasted 2 years, however the most deadly time was the Autumn of 1918 when a mutated virus was brought home to countries by returning soldiers
Medical science in that era was no where near as good as it is now and the understanding of viruses and how they infected people didn’t come about until decades later, however there was a great understanding of bacterial infections that were rife in that time, believe it or not, even back then the use of cloth masks was advised and Aspirin was the prescribed cure, the first vaccine didn’t appear until the 1940’s
It was much more deadly back then in that people died from it inside 4 days, modern medicine would probably change that figure today
I’am going to leave it there Earthman, the last word can be yours if you want it, we will probably never agree on this and as I said previously one of us will be correct
you take care
