Why Face Masks Can Capture Sub-Micron Particulate

Okay. So there is enough printed material and comments on social media about Masks to choke a very large horse or Blue Whale ( the largest animal on earth ). Does this mean that much of the information is not correct? No. Masks, of various types, styles and materials, have been used for over 100 years to minimize the inhalation of airborne particulate of all sizes. They are used daily in surgery rooms where any form of bacteria or virus can contaminate an open wound and cause serious infections. If, for example, you were wheeled into a surgery room and the Doctors and Nurses were chewing gum and had Twizzlers sticking out of their mouths and not wearing any face coverings, you would be somewhat concerned because they were not wearing MASKS….

Face coverings, masks, gators, face shields, are synonymous with Hospitals, clinics and any type of medical facility where the art of medicine is practiced. Yet, when asked to where a mask to minimize the potential transmission of a highly contagious virus we react with indignation. This virus, Covid-19, is very unique in its ability to enter the body and not show up on very accurate testing on that day. It may be four days later that it responds to the test. This is what makes this virus so sinister. And, it does affect and has killed people of all ages and all walks of life. Not just seniors and those that have underlying medical conditions. Plus, long term affects of getting this virus are still not known. 

Viruses are very tiny and are only captured by very high end HEPA based air filters. The masks are not Hepa filters and even the N90 masks have some limitations. However, there are tiny dust particles in the air that are also trapped in your face covering when you breathe in and these particles can actually assist in minimizing the amount of the virus you inhale. And the quantity of exposure over time is a big deal. So by not wearing a mask you can inhale a large quantity over a short period of time. The mask significantly reduces that high percentage of oral contact. It can be the difference between living or dying.

Un Masking Covid -19 Size Does Matter

Wearing a mask during the current pandemic has been accepted by and also rejected by large portions of the US population.Some of reasons are political, some are irrational and some are based on science. The latter being the more logical rationale.

It seems that the, “What you don’t see won’t hurt you”, mindset has taken over our ability to feel threatened by the virus. Yet, this virus like all airborne viruses has no concience or cares little about your ability to see it. You can only see particle sizes down to about 20 microns with the naked eye and this virus is about 0.005 microns in size which makes it only visible using an electron microscope. When someone who has Covid-19 talks, coughs, sings or laughs they are expelling millions of sub-micron particles into the air, some as droplets some as fine, invisible mist. The closer you are to that individual and the longer you stay in close proximity to that individual the larger the concentration of the virus you will breathe in. Unless of course you are wearing a mask.

The use of any covering over your mouth and nose is by far much safer than wearing nothing at all. Maks will prevent you from getting high concentrations and also minimize the amount of the virus you may transmit if you are infected. It is, in essence, the human thing to do.Covid -19 will continue to be with us for a long time just like the other Covid viruses for which many of us get inoculated each Fall to reduce our chances of getting the Flu. And, like the Flu this virus is always changing and the longer it stays around the more virulent it becomes and the less exposure you will need to become ill.
