Cloth face mask
A general overview of cloth face masks: construction, history, uses, effectiveness, care, and how they differ from medical masks and respirators.
Overview
A cloth face mask is a reusable textile covering intended to cover the mouth and nose to reduce the spread of respiratory droplets. Made from everyday fabrics such as textiles and frequently cotton, these masks are commonly used by the public for source control and by some workers when medical-grade options are unavailable. Their design and performance vary widely depending on fabric, fit, and layers.

Materials and design
Cloth masks are produced in many styles, from simple single-layer squares to multi-layer sewn masks with filter pockets. Effective designs typically combine several features:
- Multiple fabric layers, often a combination of tightly woven cotton and a synthetic blend.
- A snug fit across the nose and cheeks; some include a nose wire or adjustable ear loops.
- Optionally a pocket for a disposable filter or additional fabric insert.
- Durability and washability so the mask can be cleaned and reused safely.
Choice of fabric matters: tightly woven cotton and other dense weaves trap larger droplets better than loosely knit materials. Breathability, comfort, and the ability to launder the mask are also important practical considerations.
Uses and effectiveness
Cloth masks are primarily intended for source control — limiting the spread of respiratory droplets from the wearer. When well designed and worn correctly, they reduce the chance that coughs, sneezes, or speaking will project droplets into the surrounding air. Their protective value for the wearer is more limited compared with certified medical devices.
Laboratory and observational studies have reported a wide range of filtration performance for cloth masks. For example, some research has shown that a substantial fraction of small particles can pass through or around simple fabric masks; a 2010 study found that between roughly 40% and 90% of particles were not retained by some cloth masks. Because of this variability, public-health guidance typically recommends higher-grade surgical masks or certified respirators when occupational exposure is a concern.
History and recent use
Cloth face coverings have a long history in medical and civilian settings. Beginning in the 19th and early 20th centuries, rudimentary textile masks were used in surgical and clinical environments. In recent decades their use expanded outside healthcare for protection against air pollution and during outbreaks of respiratory illness. Cloth masks became especially prevalent during the COVID-19 pandemic when demand for medical masks exceeded supply and many health agencies recommended or mandated face coverings for the public.
Care, limitations and practical guidance
To be effective, cloth masks must be worn and handled properly. General recommendations include:
- Wear the mask so it fully covers the nose and mouth without large gaps.
- Wash reusable masks regularly in hot water and dry thoroughly; have several on hand to rotate.
- Replace masks that are damaged, heavily soiled, or hard to breathe through.
- Use higher-grade masks (surgical or certified respirators) for clinical settings or when higher personal protection is needed.
Limitations include inconsistent filtration across materials, reduced performance if wet or poorly fitted, and that cloth masks are not classified as personal protective equipment for healthcare workers in high-risk settings.
Notable distinctions and facts
Cloth masks differ from medical masks in certification, filtration standards, and disposable versus reusable design. Advantages of cloth masks include lower cost over time and less environmental waste compared with single-use masks, while disadvantages include variable protection and the need for regular maintenance.

History
The first recorded use of fabric face masks was by French surgeon Paul Berger during an operation in Paris in 1897.
Masks came into use in the early 20th century to protect against infection. A design by the Chinese physician Wu Lien-teh, who worked at the Chinese imperial court during a plague epidemic in the autumn of 1910, was the first to be empirically tested. It inspired masks used during the Spanish flu of 1918. The first study of masks worn by health care workers took place in 1918.
The Spanish flu (1918-1920) claimed 390,000 lives in Japan. At the time, the Japanese government put up posters with the message, "Beware of germs! You risk your life if you don't wear a mask!" Since then, the prevalence of face masks in Japan has steadily increased. Today, cloth masks are an everyday sight in public spaces in Japan; these are often single-use cellulose masks.
When Sweden was severely affected by the Spanish flu in the middle of 1918, the effectiveness of face masks was recognized within a few weeks:
["All these persons, who must be in constant contact with the sick [...], were equipped with face masks which, similar to the war gas masks, covered the whole face up to above the chin, leaving the eyes free. [...] The reason for the introduction of these masks was the fact, which had been established by our most eminent clinicians and hygienists, that the transmission of pathogens takes place more by indirect-contagious means, i.e. through the air as a medium, than from person to person (direct-contagious), from which it follows that the air of the sick room, which is particularly saturated with germs, also gives quite special opportunity for infection."
- Report of a Swedish doctor, quoted in the Fremden-Blatt, August 5, 1918.
Also in 1918, the wearing of masks was recommended in Switzerland:
"Prof. Galli-Valerio, at Lausanne, recommends that all persons who are afraid of contracting Spanish influenza should wear a mask, as the influenza is spread by saliva entering the nose, mouth, etc. The hygienic city service of Lausanne has made two models of protective masks, which have been tried in the hospital at Lausanne."
- Note in the Prager Tagblatt, 14 August 1918
By 1919 at the latest, it was known that the masks offered a certain degree of protection, despite all the problems associated with their use:
"As a prophylactic agent, the masks have been recommended from many quarters. Quite a number of models exist. The subsequent masks are very disliked by the nurses and the waiting staff, as they become slightly damp during work and then hardly allow any air to pass through. Lenz does state that one can get used to the mask. It seems to work with doctors, but not with the somewhat heavier working staff. Infections have also occurred in spite of strict wearing of the masks, but only slight illnesses. So the masks seem to provide a certain protection."
- Wiener klinische Rundschau, August 5, 1918
In the 1940s, masks made of cheesecloth were used in the USA to protect nurses from tuberculosis.
In the 1960s, their use in industrialized countries declined for hygienic reasons in favor of modern medical masks. However, they continued to be used in developing countries. Cloth face masks were largely displaced in the 1960s in industrialized countries by industrially manufactured disposable products made of multilayer nonwoven fabric. However, simple fabric masks continue to be used during infectious outbreaks, such as in Asia during the 2002/2003 SARS pandemic and in West Africa during the 2014 to 2016 Ebola fever epidemic. During the COVID 19 pandemic, which has been ongoing since 2020, mandatory wearing of face masks has been introduced in many countries (see below).
Manufacture
Due to the individual production, the variety of manufacturing methods, patterns and products is very large.
Manufacturer
In the course of the COVID 19 pandemic, there was a short-lived need for medical mouth-nose protection. Because there was no stockpile of these supplies and the need could not be met quickly enough, makeshift masks were produced by private individuals and commercial manufacturers, such as numerous professional tailors and seamstresses; or by people who otherwise work as alteration tailors or in the costume departments of theatres, for example. Larger companies also entered production. Since then, cloth masks of various kinds have been offered in the trade. In addition, makeshift masks are made in countless households and by dedicated helpers and groups themselves.
Homemade masks
Instructions for sewing DIY masks ("do-it-yourself masks") have been published by various institutions, such as the city of Essen, as well as by celebrities, including fashion designer Guido Maria Kretschmer.
In the print media and on the Internet, various ways of producing masks without sewing have also been publicised, including by the American health authority CDC. According to this, suitable mouth-nose coverings can be made with the simplest means and without tools from common household materials.
Materials
Most often, cotton fabrics are used. Homemade masks can be made, for example, from worn T-shirts, bandanas, handkerchiefs, scarves, tube towels or towels. Scientists from Hong Kong invented a DIY mask from two types of tissue paper in February 2020.
According to a study by the Max Planck Institute for Chemistry, many materials commonly used in the household are suitable for the production of masks that can reduce the risk of infection with the coronavirus: in addition to various cotton fabrics, for example, paper towels from kitchen rolls or fleeces from vacuum cleaner bags. Subsequently, a major manufacturer of vacuum cleaner bags pointed out that the vacuum cleaner bags produced by the company were not designed for use as masks.
Makeshift masks differ from the legally regulated medical mouth-nose protective masks (standard: EN 14683:2019) and respirators, which are made of several layers of fabric as well as non-woven fabric that is shaped in a melt-blow process.
