During the COVID-19 pandemic, hospitals faced a shortage of face masks, and some turned to the public for help. The CDC recommended making homemade face masks to preserve the limited supply of medical-grade masks for healthcare workers. While homemade masks may not be as effective as surgical masks, they can still provide some protection against the virus. Some hospitals accepted donations of homemade masks, especially for patients without COVID-19 or in low-risk situations. However, the effectiveness of homemade masks varies depending on the materials and construction, and they are not considered PPE by the CDC. Overall, hospitals preferred donations of factory-made N95 respirator masks and other medical-grade equipment.

What You'll Learn
Hospitals' preferences for homemade masks
Homemade masks are not considered as effective as surgical masks or N95 respirator masks, which are preferred by hospitals. According to a study, doubling the layers of fabric in a homemade mask can increase filtration efficiency, but it also makes breathing more difficult. The best materials for homemade masks, according to Cambridge University, are old t-shirts or pillowcases, which can block 51-70% of viruses.
Some hospitals are requesting specific designs for homemade masks. For example, Vanderbilt University Medical Center in Tennessee wants two-sided cotton masks with or without elastic, while Atlantic Health System in New Jersey requests tightly woven cotton on one side and a softer fabric on the other.
It is important to note that homemade masks should be washed after each use with soap and hot water (at least 60 degrees Celsius). Overall, while some hospitals are accepting homemade masks, they are not the preferred option, and hospitals would ideally like factory-made N95, surgical masks, face shields, and gowns.

Homemade masks' effectiveness
The effectiveness of homemade masks in protecting against COVID-19 depends on the material used and how the masks are made and used. A Cambridge University study found that a 100% cotton T-shirt stops 51% of the virus, while a cotton mix T-shirt stops 70%. A tea towel stops 73% of the virus, compared to 89% for a surgical mask. The CDC says N95 masks filter out 95% of small particles, making them effective against COVID-19. However, experts say cloth masks don't guarantee protection against the coronavirus. Dwayne Schlund, the Director of Milwaukee Area Technical College's Respiratory Therapy Program, warns that if the holes in the weave are too large, the particle will pass through. He also cautions that cloth masks could become a breeding ground for infection if not properly cleaned and maintained.
Some hospitals are accepting homemade masks as a last resort for patients and healthcare workers with no chance of COVID-19 exposure, preserving N95 and surgical masks for higher-risk situations. Hospitals are also requesting specific designs, such as two-sided cotton masks or masks with a tightly woven cotton interior and a softer exterior.
The available evidence on the effectiveness of homemade masks is inconclusive. While fabric masks may reduce the transmission of larger respiratory droplets, there is little evidence regarding the transmission of small aerosolized particles exhaled by asymptomatic or presymptomatic individuals with COVID-19. It is essential to reinforce the importance of physical distancing and personal hygiene, such as hand-washing, regardless of mask use.

Homemade masks' use cases
Homemade masks have been used in a variety of settings during the COVID-19 pandemic.
Hospitals
Some hospitals have accepted donations of homemade masks, particularly during periods of extreme equipment shortages. These masks are generally used for patients and healthcare workers with no chance of COVID-19 exposure, preserving more protective equipment for high-risk situations. Hospitals may also use homemade masks as a last resort for patients without COVID-19. In some cases, healthcare providers use homemade masks as a cover for their N95 masks, allowing for quick changes between patients.
Doctors' Offices
Homemade masks can be used in doctors' offices, helping to relieve mask shortages and ensuring that N95 masks are available for critical situations.
Retirement Homes
Retirement homes have also used homemade masks, particularly for individuals who are sick or caring for someone who is sick.
General Public
The general public has used homemade masks when going outside during the pandemic. These masks can help decrease the spread of large particles when someone sneezes and may be useful in preventing the spread of the flu, cold, and other airborne illnesses. However, it is important to note that homemade masks do not provide the same level of protection as surgical masks, and individuals with COVID-19 symptoms should stay inside.

Homemade masks' designs
During the COVID-19 pandemic, shortages of approved respirators and face masks have led to a rise in the use of homemade masks. While homemade masks are not as effective as surgical masks, they are recommended by the CDC as a last resort when no other options are available.
There are many designs for homemade masks, and their effectiveness varies depending on the materials used and the construction. The efficacy of a mask in reducing the risk of infection is dependent on the behaviour of the wearer and those around them. However, the filtration efficiency of the mask, or its ability to filter particles, is often used as a quantifier of effectiveness.
A study by Cambridge University found that a 100% cotton T-shirt stopped 51% of viruses, while a cotton mix T-shirt stopped 70%. A tea towel stopped 73% of viruses, but it was difficult to breathe through. The study recommended using a T-shirt or pillowcase, which stopped 57% of viruses, as a suitable material for a homemade mask.
Another study used a dynamic-spread model to simulate the performance of different mask designs in various COVID-19 scenarios. It found that a 3-layer cotton-gauze-cotton mask with 44% filtration efficiency reduced the number of new infections by 30% in a New York State scenario and 60% in a Harris County, Texas scenario, compared to a cotton T-shirt with 8% filtration efficiency.
When making a homemade mask, it is important to use materials that are breathable and effective at filtering particles. Designs may vary, but some common materials used include cotton fabric, filter fabric, soft plastic sheets, sewing thread, elastic bands or tape, and bendable nose pieces. It is recommended to wash homemade masks with soap and hot water (at least 60 degrees Celsius) after each use.
Some hospitals have accepted donations of homemade masks, particularly for patients and healthcare workers with no chance of COVID-19 exposure. However, it is important to check with your local hospital to see if they are requesting homemade masks and if they have any specific design requirements. For example, Vanderbilt University Medical Center in Tennessee requests two-sided cotton masks with or without elastic, while Atlantic Health System in New Jersey asks for tightly woven cotton on one side and a softer fabric on the other.

Homemade masks' donation
Homemade masks can be donated to hospitals, doctors' offices, and retirement homes. They can help relieve the strain of a mask shortage and allow N95 masks to be used for COVID-19 and critical situations requiring PPE. Hospitals may use homemade masks for patients and health-care workers with no chance of COVID-19 exposure, preserving more protective equipment for higher-risk situations. For example, a patient with a non-COVID-19 cough could use a homemade mask to contain saliva droplets. Health-care workers in very low-risk situations could also use the masks in conjunction with a face shield or goggles.
The CDC recommends making homemade face masks to help protect and preserve the limited supply of medical face masks for the medical community. Hospitals are in need of factory-made N95, surgical masks, face shields, and gowns, so these should be donated if possible. However, if you do decide to make masks, check whether your local hospital is requesting a specific design. For example, in Tennessee, Vanderbilt University Medical Center wants two-sided cotton masks with or without elastic, while in New Jersey, Atlantic Health System requests tightly woven cotton on one side and a softer fabric on the other.
If you are making masks for donation, it is important to use appropriate materials and construction techniques to ensure the masks provide adequate protection. A study by Cambridge University found that a cotton T-shirt or pillowcase is a good material for a homemade mask, blocking 51-70% of viruses. A tea towel performed even better, blocking 73% of viruses, but it was difficult to breathe through. It is also important to ensure that the mask fits well around the nose and mouth to prevent infectious aerosols from passing through.
When making homemade masks for donation, it is also important to consider the comfort of the wearer. Double material can make breathing more difficult, so it is important to find the right balance between protection and breathability. It may be helpful to include flexible nose pieces or pipe cleaners in the design to improve the fit. It is also important to use elastic that is long enough to be comfortable, especially for men, as the elastic may not stretch as much as desired. Finally, be sure to provide instructions for using and caring for the masks, including washing and sterilizing before and after use.
