Did you know that the earliest "masks" appeared in the sixth century BC? Do you know how the mask developed into what it is today? This year, due to coronaviruses, the demand for masks is increased several hundred times or more than the past. However, everyone's understanding is only on its function. Today Vmartego will take you to understand the history of mask development.
In the sixth century BC, the Persian Zoroastrian doctrine stipulated that the worldly atmosphere was turbid and unclean. Therefore, when holding major religious and sacrificial activities, priests often needed to wrap their faces with cloth to participate.
This should also be the earliest "mask" in human history. However, the "mask" of this era has nothing to do with the protective effect. It is more a kind of symbol representing the status of the identity. Often, only nobles and priests are qualified to use it.
Plague doctor costume
I believe everyone is familiar with this mask, and now it often appears in many horror movies. During the prevalence of the Black Death in Europe in the Middle Ages, many doctors who had direct contact with patients were extremely likely to be infected with the plague and dead. This is how this mask was born.
In 1619, Charles de Lorme, invented this plague doctor costume in order to reduce the probability of doctor infection. At this time, the mask is already considered protective. Therefore, this mask should be the first "mask" used by humans in the field of medical protection.
The birth and application of masks
In 1895, German pathologist Drech discovered that the bacteria in the air would infect the wounds of patients, so he recommended that doctors use gauze to cover the nose and mouth during the operation. Which greatly reduced the number of infections of patients and doctors. Until 1899 that a French doctor made a mask composed of six layers of gauze, and then changed it to a circular strap hung on the ears. The modern mask was officially born.
KN95 and N95 are effective masks. "N" means not resistant to oil. "95" means that when exposed to a specified number of special test particles, the particle concentration in the mask is more than 95% lower than the particle concentration outside the mask. The 95% value is not the average value, but the minimum value. That means that the filter efficiency of the mask filter material for non-oily particulate matter (such as dust, acid mist, paint mist, microorganisms, etc.) reaches 95%.
Based on the current situation of Coronavirus Cases and many recent events, Vmartego would like to say, if you can, please be sure to wear a mask. Because this can protect your body very well. If you need you can search " KN95", we have some this which in a lower price and high quality.
