Here is a common-sense argument against most Covid-19 masks, that the actual virus is smaller than the holes in the mask, so in principle it can get through. Maybe that intuition lies behind the wearing of multiple masks, but that claim too is in need of scientific evaluation.

“The best data to date indicates that the use of surgical or simple face masks are insufficient in most “Covid safety” situations. Even the N95 mask packaging has label verbiage indicating protection that can only go down to 0.3 microns, yet the Covid-19 virus particles have a diameter of approximately 60–140 nm, and that’s 0.06 to 1.4 microns. Did you pass third grade arithmetic? If not, we can help you now.
Let’s break that down elementary style. The decimal .06 is 5 times smaller than .3. That means the Covid virus particles are 5 times smaller than the holes in nearly every mask that nearly every American is wearing. That’s like tossing a basketball through a hula hoop.
It doesn’t take a genius or scientist to see that most masks people are buying on Amazon, at stores, or making themselves (like from cotton/bandanas) have holes with diameters of 3 to 5 microns, rendering them virtually useless in preventing the spread of Covid, whether from the person wearing the mask or being transferred to them by others.
Regardless of how far your saliva or mucus travels when you talk, scream, sing, sneeze or cough, the virus still escapes from these homemade masks, so it’s all psychological for the mask wearer, until mouth bacteria begin infecting the mask-wearing victim. This can lead to pneumonia, and every doctor in America is currently trained to never blame the mask.
If the CDC knows that most masks are worthless, why is America under mask “seige” 24/7/365?
The Democrats are in control because of Covid. Make no mistake. The virus and the masks were all a cover (pardon the pun) for mail-in ballots, as those were the prime way the election was stolen, including up to 40 million fake ballots for Biden. By convincing America it was safer to vote from home, that justified the entire fraudulent scheme, and China printed tens of millions of fake ballots for Biden for all the swing states, and then some.
Maybe all humans should be going to stores and schools and hospitals carrying battery–operated HEPA filters, because those are great at capturing particles down to 0.01 microns, and that’s 6 times smaller than the Covid virus particles. Think of Covid masks like a basketball net and the virus like sand. That’s why masks are worthless and the US government should fund the manufacturing of 330 million battery-run HEPA filters for everyone to carry around all day when they leave the house, including small children at daycare centers and elementary schools.
The MPPS, or “most penetrating particle size” like Covid-19 virus particles, require fiber filters, not homemade bandanas, scarves and neck gaiters.
Ever heard of Brownian Motion? Most hospitals use HEPA filters to capture viruses, as they usually fall in the micron size range above and below .3 microns. You see, airborne viruses attach to other particles, so they don’t need your spit or mucus to travel to other people, they simply escape the masks when you breathe. Get it?
Plus, nary a human being wearing a mask remembers not to touch their eyes, nose, mouth and mask repeatedly, or face the consequences of spreading the virus to and from the very mask that you’re wearing for protection. In other words, the mask itself becomes the primary vehicle for spreading Covid. This raises a number of new concerns to be considered very carefully.
It is a fact that without airflow, you receive zero oxygen, and suffocate to death. It is also a fact that all Covid masks restrict some airflow, of course, some more or less than others, but still the fact remains. That means less oxygen is flowing through the human body on a regular basis, and for most Americans who are at work or school, that’s all day. This leads to fewer nutrients flowing through the body, and thus a lower resistance to diseases, including infectious diseases being spread by faulty masks.”
However, here is a contrary position:
“The claim: "N95 masks block few, if any" COVID-19 particles due to their size.
As many states and communities ease restrictions related to the COVID-19 pandemic, the debate over mask usage has intensified.
Businesses, churches and governments have implemented all manner of policies — some requiring masks, some leaving it up to each person, some even banning masks. And that has spurred many armchair epidemiologists to weigh in, including a Facebook page with nearly 1 million followers.
A June 4 post from Why don’t you try this? went a step beyond the homemade mask debate to claim that even the N95 masks used by health care workers are pointless in the face of COVID-19.
“COVID 19 virus particle size is 125 nanometers (0.125 microns); the range is 0.06 microns to .14 microns,” the post said. “The N95 mask filters down to 0.3 microns. So, N95 masks block few, if any, virions (virus particles).”
In other words, the post asserts the virus is smaller than the filter on the N95 mask, so the N95 mask doesn’t work.
Experts say this claim flies in the face of numerous studies and reflects a failure to grasp fundamental principles of how viruses behave and how face masks work.
Virus particles don’t exist alone.
The science of mask functionality gets really small, really fast. The unit of measurement here is microns — 1/1000th of a millimeter.
The size-based argument against N95 laid out in this claim assumes mask filtering works something like water flowing through a net — particles in the water smaller than the net opening pass through, while larger items don’t.
But the physics involved don’t work like that at all.
The COVID-19 particle is indeed around 0.1 microns in size, but it is always bonded to something larger.
“There is never a naked virus floating in the air or released by people,” said Linsey Marr, a professor of civil and environmental engineering at Virginia Tech who specializes in airborne transmission of viruses.
The virus attaches to water droplets or aerosols (i.e. really small droplets) that are generated by breathing, talking, coughing, etc. These consist of water, mucus protein and other biological material and are all larger than 1 micron.
“Breathing and talking generate particles around 1 micron in size, which will be collected by N95 respirator filters with very high efficiency,” said Lisa Brosseau, a retired professor of environmental and occupational health sciences who spent her career researching respiratory protection.”
Perhaps then the N95 masks are adequate, but there is still the issue of virus particles being on very small droplets or minute dust particles, still getting through the barrier. But, assume that they do not. Most mask wearers simply have face coverings, even cloth. There is no argument that such masks would be struggling to offer protection from even dust. Simply try dusting a shed with such coverings, and spend the rest of the day coughing.
