Planar masks are divided into: cotton mask, non-woven cloth mask, polymer material mask, activated carbon powder filter element mask, activated carbon fiber mat mask.

 

China was the first country in the world to use masks. In ancient times, people in the court to prevent dust and breath pollution and began to use silk scarves to cover the mouth and nose, such as "li shu" contained: "cover the mouth, fear of gas contact people. And "mencius · from Lou" record: "the west is not clean, then people are covering their nose." Covering your nose with your hands or sleeves is not sanitary or convenient for other things. Later, some people used a silk cloth to cover their mouth and nose. In his book the travels of Marco Polo, he described his experiences of living in China for seventeen years. One of them said, "in the yuan dynasty, those who offered food covered their mouths and noses with silk cloth, so that they could smell and not touch the food." This silk cloth covering the mouth and nose is the original mask.

In the early 13th century, masks appeared only in the Chinese imperial court.To prevent breath from reaching the emperor's food, the waiters used a towel made of silk and gold thread as a mask.

In the late 19th century, masks began to be used in medical care.

German pathologist lederch began advising health care workers to use gauze masks to prevent bacterial infections

At the beginning of the 20th century, masks became a necessity for the general public for the first time.

The global outbreak of the Spanish flu has killed an estimated 50 million people, and the general population has been asked to wear masks to ward off the virus.

In the mid to late 20th century, the use of masks on a large scale became apparent.

Masks have played an important role in preventing and stopping the spread of germs in several flu pandemics.

In 1897, the German Medici introduced a way to protect the mouth and nose from bacteria by wrapping them in gauze.

Later, someone made a mask with six layers of gauze and sewed it on the collar.

When used, turn over and cover your mouth and nose.

However, this mask has to be held down by hand all the time, which is inconvenient.

Then someone came up with the idea of wearing a belt around the ear, which became the mask that people often use today.

In 1910, when the plague broke out in Harbin, Dr. Wu liende, deputy supervisor of beiyang army medical college, invented the "wu-style mask".

In 2003, the use and popularization of face masks reached a new climax. A SARS epidemic almost made face masks out of stock for a time.

In 2009, after the "bird flu" in 2004, the "a (H1N1) flu" army of masks appeared in front of the world's major news media once again.

The emergence of the concept of PM2.5 air hazards in 2013 has aroused the public's attention to air pollution, making masks and other protective products very popular during the haze weather.
