The infamous virus is fast spreading all over the world right now and it is understandable why so many people are afraid of it. Most of those who do not want to contract the virus are looking for the best face mask for virus protection.
Lots of Chinese Masks Available in the Market starting from Rupees 100 to 300.
But not all face masks can protect you from viruses and because the virus is still spreading, knowing which ones are effective is of the utmost importance. The following article will teach you all of the things that you need to know about the right kinds of face masks and why face masks are good preventative measures against the virus.
So far only 3M (N95) and DR.MFYAN (KN95) are the only branded products available in the market.
Benefits of N95 Mask
The mask is called N95 and not “N let’s see what can and can’t get through the mask.” N95 means that the mask can filter out at least 95% of particles of all sizes from the air. That includes something less than 0.1 microns in size and something as large as a watermelon. Note, if watermelons are flying through the air, it helps to duck as well.
Basically, the mask needs keep the virus from reaching your nose and mouth, which is why wearing panty hose over your head like a gangster isn’t going to do the trick. “Something like panty hose is too porous,” explained Sundaresan Jayaraman, PhD, the Kolon Professor at the Georgia Institute of Technology School of Materials Science & Engineering. “That’s the case with many types of fabric. Even when you use several layers of fabric, it may have too many holes.” He added that one layer of a handkerchief or bandana is only going to filter out less than 10% of particles.
WHO Research on why masks are not necessary unless ur an affectee or near one.. (unless WHO has changed stance)
The World Health Organization (WHO) is considering changing its guidance on whether people should wear face masks in public, prompted by new evidence that suggests doing so could help contain the pandemic.
Dr Peter KaHung Chan, an epidemiologist at the University of Oxford, said that the evidence on public use of face masks is still unclear, but that observational studies from Hong Kong have, at least, shown that the overall package of containment measures have been effective. “Face masks are certainly not the only thing that was useful, but they’re something that should be studied properly instead of dismissed or excessively promoted with inadequate empirical evidence,” he said.
Until now, the WHO has suggested that masks are mostly useful for protecting other people if you have symptoms such as coughs and sneezes that could spread droplets. But Heymann said the realisation that a lot of transmission of Covid-19 occurs before symptoms raises the possibility that masks could help stop the spread among people before symptoms emerge.
“One or two days before symptoms develop, it seems [people] may be shedding virus at that time and it may be that if they’re talking and spewing droplets around they may be spreading the virus,” he said.
“As the evidence becomes available it seems that there will be a more serious debate [including] tomorrow at the WHO trying to decide whether masks really do play a role at some point in the outbreak containment,” he added. “Believe me if they do, there’s a private sector healthy enough in many countries to begin producing those masks in the quantities that are necessary.”
