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.

Ashes To Ashes, Dust To Dust

In 1662 the “Book of Common Prayer” was written an one of the prayers in the book was dedicated to burial services.  The prayer is four lines long but part of it reads “….we therefore commit his body to the ground, earth to earth, ashes to ashes, dust to dust. It’s interesting that this part of the burial service prayer is the most often used in TV, movies and books when showing a burial scene or describing one in print. It’s also interesting to note that all things that die and have died and that have decomposed above ground and turned into dust are still with us.

All this dust keeps getting pushed around by the winds. It continues to get smaller as it comes in contact with a solid object or another particle when it is picked up by the wind. These particles are so small that they can’t be seen with the naked eye ( usually less than 20 microns in size, your hair is 100 microns in diameter ) but they are there none the less. Many of these particles are in the sub-micron range, meaning they are less than 1 micron in diameter. These small particles are easily inhaled and a large percentage of them can be trapped in the mucus membranes and lungs. And, these particles can create havoc with your respiratory system.

People that suffer from allergies due to exposure to ragweed, pollen, grasses and other airborne allergens are much more susceptible to reacting to other airborne particulate that may not necessarily be one of their known allergens. This may be why allergy sufferers who get shots or take anti-histamines may still have their allergic symptoms. For these individuals being outside, especially during the warmer weather, can be a problem. Even being indoors doesn’t always help as these fine particles are brought in on their clothing and through any communications between the outdoors and inside.

To remove these fine particles from the air in your home you will need to use air filtration systems or filters that can trap and contain these finer, smaller particles. While there are a number filtration and air purifying systems available on the market today, only HEPA based filtration systems can really remove the smaller, sub-micron particulate.

Pure Air Systems has been making commercial grade, certified, HEPA and Carbon based air filtration systems since 1985. They have thousands of systems installed in commercial, residential, industrial, institutional and medical facilities around the world. Their wide range of HEPA filtration platforms allows you to select the filtration system that fits your specific needs. Whether you want to install the systems as part of your HVAC unit or use it as a stand-alone filtration device PAS units will meet your requirements.
