What’s the Difference Between a Premium, Surgical Style Mask and Others?

In considering mask alternatives, there is virtually no face mask capable of 100 filtration of ultra-fine particulates or microscopic viruses. Whereas most masks are designed for filtering particulate matter, viruses such as SARS-COVID-2 are much smaller. SARS-COVID 2 is a relatively large virus, yet it’s observed to be only 70–90 nm, about 0.07 – 0.09 micron.

In contrast, a HEPA filter must capture a minimum of 99.97% of contaminants at 0.3 microns in size. N95 masks are considerably less effective than HEPA filters. An N95 mask captures only 95% of very small (0.3 micron) test particles.

“The bare influenza virus is approximately 0.1 micron, but the influenza virus expelled from humans via respiratory secretions is typically much larger at 0.8 micron. (Harnish et al., “Challenge of N95 Filtering Facepiece Respirators”

To some, the difference between 95% capture and 99.97% might seem trivial, but when a single sneeze could hypothetically contain 40,000 aerosol droplets between 0.5–12 μm in diameter, let’s consider the math:

A sneeze may produce 40,000 droplets

One droplet may contain 3000 droplet nuclei

Droplets X Virus Nuclei = 120,000,000

So, if we look at the hypothetical filtration of a single sneeze containing viral droplets:

99.97% filtration rate: 36,000 Virus Nuclei remain

98% filtration rate: 2.4 million Virus Nuclei remain

95% filtration rate: 6 million Virus Nuclei remain
