Five types of masks were examined: an N95/ KN95 mask, surgical mask, a cloth mask, a two-layer cloth mask and a wet two-later cloth mask.
Each mask was tested with a machine that uses an air generator to blow tiny liquid droplets, like those that would escape from a nose or a mouth
The N95 /KN95 blocked the most at 100% of droplets and the regular cloth mask blocked the least at 96.4% of droplets
The cloth mask allowed more than 1,000 sneeze droplets and the two-layered cloth mask let through more than 600 sneeze droplets
Researchers say each droplet could contain millions of virus particles that, when standing less than six feet apart, could be breathed in and infect others.
Studies show wearing a cloth mask may not shield the user from coronavirus as too many infected droplets can slip through. Scientists found that while all masks blocked at least 95 per cent of droplets from coughs and sneezes - there was still a high risk of the disease being spread. Although cloth masks stopped 96.4 per cent of sneeze droplets at a distance of six feet, they still let more than1,000 through - which the scientists said could carry enough virus particles to trigger an infection.
As documented in Physics of Fluid,the team built a machine that mimics coughs and sneezes from humans. It uses an air generator to blow tiny liquid droplets, like those that would escape from a nose or a mouth. The machine was tested on five different types of masks: an N95 / KN95 mask, surgical mask, a cloth mask, a two-layer cloth mask and a wet two-layer cloth mask. Each of the masks were able to block most of the droplets with thebest-performing beingthe N95 / KN95, which blocked 100 percent of droplets. Meanwhile, the worst was the regular cloth mask, which only blocked 96.4 percent of the droplets. At distances of less than six feet, allowing three percent of droplets is enough to make someone ill. The average infection threshold for COVID-19 is 1,000 virus particles, inhaled either all at once or on separate occasions.A single sneeze has the potential to carry up to 200 million virus particles.
The cloth mask allowed more than 1,000 sneeze droplets, each of which could have millions of virus particles. The two-layered cloth mask let through more than 600 sneeze droplets.This means that if someone wearing one of these masks is close to an infected individual, enough dropletscould escape to make them contract COVID-19.Please stay safe out there and do your best to follow the CDC guidelines. Remember dont just wear a maskwear an effective mask to keep you and everyone around you safe.
