cloth face mask is a mask made of common textiles, usually cotton, worn over the mouth and nose. When more effective masks are not available, and when physical distancing is impossible, cloth face masks are recommended by public health agencies for disease “source control” in epidemic situations to protect others from virus laden droplets in infected mask wearers’ breath, coughs, and sneezes. Because they are less effective than N95 maskssurgical masks, or physical distancing in protecting the wearer against viruses, they are not considered to be personal protective equipment by public health agencies. They are used by the general public in household and community settings as protection against both infectious diseases and particulate air pollution.

Cloth face masks were routinely used by healthcare workers starting from the late 19th century until the mid 20th century. In the 1960s they fell out of use in the developed world in favor of modern surgical masks.

General Information about face mask

  Face Masks are classified into civilian masks and medical(Surgical) masks. A civilian mask is used for the purpose of filter air into the mouth and nose to prevent harmful gases, odors, and droplets from entering and leaving the wearer’s mouth and nose. Civilian(Non Surgical) masks mainly divided into cotton mask, non-woven mask, polymer material mask, activated carbon powder filter mask, activated carbon fiber felt pad mask. Medical masks can prevent most of the bacteria, viruses and other pathogens, and WHO recommends that medical personnel use protective masks (N-95 masks) against particles to prevent virus infection in the hospital air. Medical masks mainly divided into medical protective masks, medical surgical masks, general medical masks.

There are three commonly used masks on the market: cotton masks, medical surgical masks and medical protective masks (N-95 masks), among which medical surgical masks can block 70% of bacteria, N-95 masks can block 95% of bacteria, and cotton masks can block only 36% of bacteria.

Wearing a mask is NOT a reliable way of preventing an infection by the COVID 19 virus or other forms of coronaviruses. It is good for someone infected to wear a mask to reduce the risk of infecting other people. But it is not a 100% safe approach.
