FAQ

Think of a large Bolder Rock having a diameter of 1 meter - representing a Bacteria. Now think of a tiny little Sand freckle of 1 mm - representing a Virus. Now try to place this little sand freckle into the Rock in one line 1000 times - hard to imagine and hard to do, but this is the approximate size difference.

It is Viruses that attack the cells of organisms, like the single celled Bacteria (Microbe) and therefore one can say, that Viruses are literally cell & Bacteria eaters, that are the most abundant of all with these viruses present in huge numbers in a host of different environments ranging from soils to air and to rivers and oceans.

When a virus attacks and settles in another living cell structure like a human, an in-built mechanism called "Immune System" kicks in trying to fight the virus.

The immune system is a complex network of cells and proteins that defends the body against infection. The immune system keeps a record of every germ (microbe) it has ever defeated so it can recognize and destroy the microbe quickly if it enters the body again. 

Depending on the hosts Immune System condition, age of the host, general health condition and other factors, a virus attack can be in the worst scenario lethal.

The COVID-19 CORONA VIRUS variant is a vicious Virus attacking the lung respiratory system.

THE SHORT ANSWER IS - YES - 

Wear a Face-mask!

WHY FILTERS OR FACE-MASKS CAN CAPTURE A VIRUS?

Because, what scientists call, the BROWNIAN MOTION of Nano-Particles and a Virus is a Nano-Particle

Nano-particles are so small that they bounce around like a pinball when they hit gas molecules ( Brownian Motion ). Air is about the same size then a small Virus and Air is made mainly from gases like nitrogen 78%, oxygen 20%, argon and other trace gases. That means Nano-particles like Viruses fly in random zigzag patterns and Nano-particles are so small, that they can fit through the fibers in filters, but they get stuck anyway. Flying in random zigzag patterns mean they end up hitting the fibers and getting stuck.

When a filter captures a nano-particle in this way, scientists call it “diffusion” and this applies not only to HEPA Filters, but also to Face Masks, though the efficacy is different. 

OK, so diffusion captures nano-particles. But how many nano-particles? Maybe 50% of nano-particles? It turns out that diffusion is far more effective than that. According to NASA, HEPA filters capture “virtually 100% of particulates.” - Face-Mask efficacy is much lower, depending on breathing intensity, materials used and handling.
