What are the best fabrics and materials for antiviral face masks? In the effort to slow the spread of Coronavirus, CDC now recommends that the general public should wear cloth face coverings. These are non-medical face masks made using materials such as fabric, cloth, and scarves. However, when it comes to making your mask, you might be wondering about the best fabrics and materials that you can use.

What are the best fabrics and materials for antiviral face masks? The best fabrics and materials that you can use for making antiviral face masks should be dense enough to capture viral particles, but breathable enough so that you can wear them comfortably. According to a studyOpens in a new tab. made by researchers at Cambridge University, the pillowcase and the 100% cotton t-shirt are among the best materials for making homemade cloth face covering.

Best Materials for DIY Antiviral Face Masks

According to the same study published by the researchers at the Cambridge University, the vacuum cleaner bag, dish towel, cotton blend t-shirt, 100% cotton t-shirt, pillowcase, silk, linen, and scarves are some of the best materials that you can useOpens in a new tab. when making DIY antiviral face masks. See to it that you balance the filtration and breathability of the face mask when choosing a material. For instance, vacuum bags are great for filtration but they make breathing difficult. Cotton t-shirts are breathable but they lack a high level of filtration.

Neal Langerman, a chemical safety expert said thatOpens in a new tab. the permeability of household materials can vary widely and in unpredictable ways, making it hard to determine which material is best for a homemade face mask. One factor to consider is how tightly a material is woven as well as the type of fibers used.

According to Yang WangOpens in a new tab., an aerosols researcher at the Missouri University of Science and Technology, “The difficulty is that different fabrics have different specifications, and there seem to be so many options on the market.”

In the post, we have shared tips on how you can create a face mask that will fit in your face and will not easily fall off by using rubber bands into it. We have provided different methods of making face masks with rubber bands that you can follow.

Consider the Ability of The Fabric to Block Viruses

Viruses are much smaller as compared to bacteria and those that measure less than one micron in size can escape most fabrics. According to Dr. Erum IlyasOpens in a new tab., a board-certified dermatologist and founder of the protective clothing line AmberNoon, various household materials have been studied to determine their ability to block viruses. Choosing the right material can determine the best chances of blocking viruses and also ensure comfort. A study of various household fabricsOpens in a new tab. to block the spread of influenza showed that cotton and polyester blends are the most effective out of all the household materials while maintaining breathability.

A study about the filtration performance of cloth masksOpens in a new tab. and common fabric materials against 20–1000 nm size particles states that “The use of fabric materials may provide only minimal levels of respiratory protection to a wearer against virus-size submicron aerosol particles (e.g., droplet nuclei). It is partly because fabric materials show only marginal filtration performance against virus-size particles when sealed around the edges. Face seal leakage will further decrease the respiratory protection offered by fabric materials.”

✅ Tweet – Effectiveness of Household Materials at Capturing Virus-Sized Particles

Dr. C Michael Gibson shared a tweet about how effective some household materials as compared to surgical masks. In the data that he has provided, it shows that the vacuum cleaning bag, dish towel, and t-shirt can capture the most particles.

We have also written an article about how to make a face mask with hair ties. In the article, we have gathered the different materials that are used to make ties for face masks. We have also shared tutorials and patterns on how to make face masks with hair ties. Check out the articles to learn the many ways to make face masks using various materials for hair ties.

Some Materials Are Better Than Others

When it comes to preventing particles from penetrating through the mask, some materials are better than others. This will have to depend on how tightly-woven the fabric is and whether it is a good and tight fit. A study done by the National Institute for Occupational Safety and Health (NIOSH)Opens in a new tab. in 2010 tested how well tiny particles can penetrate different materials like scarves, towels, cotton t-shirts, and sweatshirts. According to the study, sweatshirts offer slightly better protection as compared to t-shirts against the particles. They can block about 20-30% of particles as compared to 14% of the t-shirt. Hanes brand sweatshirts were found to be the most effective and can block 43-60% of particles.

Moreover, other factors like how often the materials are worn or washed can also influence their effectiveness. Take note that medical masks are designed to be single-use and disposed of after they may have come into contact with viruses and bacteria. Reusing the DIY face masks without washing it could reduce its effectiveness. According to the CDC guidelinesOpens in a new tab., cloth face masks should be routinely washed depending on the frequency of use. You can use a washing machine in properly washing a face covering.

Make sure that the face mask is secured around your face by using elastics as ear loops. Check out this post about the best elastic for face masks and find out the different kinds of elastic that you can use in making a mask. We have also shared tutorials on how to make a mask with elastics.

Two-Layered DIY Antiviral Face Masks Are Not Effective

When it comes to filtration effectiveness, is it better to double up two layers of fabric? A group of scientists tested virus-size particles against double-layer materialsOpens in a new tab. like a pillowcase, dish towel, and 100% cotton shirt fabrics. As a result, the double layers are not that effective. For instance, the double-layer pillowcase captured 1% more particles, while the double-layer shirt captured just 2% more particles. On the other hand, the double-layer dishcloth boosted performance by 14%, which makes it as effective as the surgical mask.

The result of the study states thatOpens in a new tab. the dish towel is the top-performing material. On the other hand, the researchers did not choose it as the best material for a DIY face mask. The reason for this is breathability. While the dishtowel captured the most particles, it is also the hardest to breathe through. With the two layers of a dish towel, it is twice as hard to breathe.

How Effective Are Baclavas or Scarves?

According to Rachel NobleOpens in a new tab., a public health microbiologist at UNC at Chapel Hill, “balaclavas and other warm-weather gear designed to cover your nose and mouth is unlikely to be suitable for preventing the spread of COVID-19. Because they’re designed to be as easy to breathe through as possible, they tend to be made of loose fabrics.” The best choice is a tightly-woven fabric or something that’s approximately the density of the weave of a bandana or a high-quality bedsheet.

Check out this post about how to make a face mask with hair ties for more tutorials and patterns. We have shared different methods to make a face mask using hair ties. It is a great alternative to use if you do not have rubber bands or elastics. Hair ties will serve as the ear loop that secures the mask on your face.

Conclusion

You need to choose the best fabrics and materials when making DIY antiviral face masks. Many choices are available. According to studies, some of the best materials include pillowcases and 100% cotton t-shirt. These materials provide high filtration and are also breathable. Vacuum cleaning bags and dish towels also provide high filtration against small particles, but they are hard to breathe through. Lastly, avoid scarves and baklavas that are made of loose fabrics because they provide less filtration against small particles. When choosing a material, it is ideal to choose one that offers high-filtration and is also comfortable to wear. Thank you for reading!
