General public

In community and home settings, the use of facemasks and respirators generally are not recommended, with other measures preferred such as avoiding close contact, maintaining good hand hygiene,^[18]and wearing cloth face coverings.^[24] Surgical masks are popularly worn by the general public all year round in East Asian countries like China, Japan, South Korea and Taiwan to reduce the chance of spreading airborne diseases to others, and to prevent the breathing in of airborne dust particles created by air pollution.^[14]In Japan and Taiwan, it is common to see these masks worn during the flu season, as a show of consideration for others and social responsibility.^[25][26][27] Surgical masks provide some protection against the spread of diseases, and improvised masks provide about half as much protection.^[28]More recently, due to the rising issue of smog in South and Southeast Asia, surgical masks and air filtering face masks are now frequently used in major cities in India, Nepal and Thailand when air quality deteriorates to toxic levels.^[29][30][31] Additionally, face masks are used in Indonesia, Malaysia and Singapore during the Southeast Asian haze season.^[32][33] Air filtering surgical-style masks are quite popular across Asia and as a result, many companies have released masks that not only prevent the breathing in of airborne dust particles but are also fashionable.^[34][35]Additionally, surgical masks have become a fashion statement, particularly in contemporary East Asian culture bolstered by its popularity in Japanese and Korean pop culture which have a big impact on East Asian youth culture.^[15][16]

Function

Surgical masks retain some of the respiratory droplets released from the wearer through talking, coughing, or sneezing. Thus they reduce the spread of pathogens.^[37]

Disposable Face Masks are loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment. If worn properly, a surgical mask is meant to help block large-particle droplets, splashes, sprays, or splatter that may contain viruses and bacteria, keeping it from reaching the wearer’s mouth and nose.^[39] Surgical masks are effective barriers for retaining large droplets released from the mouth and nose by the wearer in public.^[37] Surgical masks help reduce exposure of the wearer’s saliva and respiratory secretions to others^[39] that could otherwise travel up to 26 feet.^[40] Surgical mask also remind wearers not to touch their mouth or nose, which could otherwise transfer viruses and bacteria after having touched a contaminated surface.^[38]A surgical mask, by design, does not filter or block very small particles in the air that may be transmitted by coughs, sneezes, or certain medical procedures. Surgical masks also do not provide complete protection from germs and other contaminants because of the loose fit between the surface of the face mask and the face.^[39]A surgical mask is not to be confused with a respirator and is not certified as such. Surgical masks are not designed to protect the wearer from inhaling airborne bacteria or virus particles and are less effective than respirators, which are designed for this purpose.^[37] Collection efficiency of surgical mask filters can range from less than 10% to nearly 90% for different manufacturers’ masks when measured using the test parameters for NIOSH certification. However, a study found that even for surgical masks with “good” filters, 80–100% of subjects failed an OSHA-accepted qualitative fit test, and a quantitative test showed 12–25% leakage.^[41]Modern surgical masks are made from paper or other non-woven material and should be discarded after each use.^[18]
