Finding and Selecting Polypropylene for Washable Masks

In this post we discuss how we think about selecting spunbond nonwoven polypropylene (NWPP) fabrics for washable masks, where we have found spunbond NWPP, and why we’ve chosen Smart-Fab® Double-Thick for our next round of testing. Our Mission Our mission is to share information with the public about the best emerging mask science to help […]

Constructing Masks for Singers

Dr. Jocelyn Songer In this guest blog post, Joan Fearnley, a soprano, a choir director, and the creator of the open source “Singer’s Mask” pattern/design, teams up with MakerMask to discuss some of the science and special considerations for masks for singers. The five sections of this post answer key questions about masks for singers: […]

Research Highlights: NWPP Filtration Efficiency from Long et al 2020

This post is the first in a series of “Research Highlights” where we discuss select data and research from the literature in the context of community mask making efforts. In this post, we take a look at the filtration and breathability data for nonwoven polypropylene (NWPP) mask materials presented in: Long KD, Woodburn EV, Berg […]

Fluid Resistance: Mask Material Test Results

New test results show that upcycled spunbond nonwoven polypropylene (NWPP) mask materials can provide high-level (ASTM Level 2) fluid resistance. MakerMask has supported the use of spunbond NWPP in homemade mask designs because of its unique combination of breathability and hydrophobicity, or water resistance. Thanks to community contributions, we were able to put the fluid […]

5 Key Considerations For Window Masks

One of the challenges with face masks is that they often cover key facial features and expressions that are important for communicating speech and emotions. For many people, this means missing out on smiles, and having a little bit more trouble understanding other people in noisy environments. For people that are deaf, hard of hearing, […]

Homemade Mask Summit: Masks Unmasked

In June 2020, the team coordinating the Homemade Mask Virtual Summit at Tulane University interviewed Dr. Songer about the science behind masks and invited Dr. Songer to give the Keynote Address for the summit. This post contains the audio and transcripts of Dr. Songer’s Keynote Speech: “Masks Unmasked: A Look at the Science Behind Fabric […]

Masks for the Blind During the COVID-19 Pandemic

In this post, we hear from Matt White, who shares with use some of his experience and observations about masks for the blind. This is part of a series of guest blog posts where we get a chance to hear voices and perspectives about making masks more accessible. With government agencies around the country and […]

WHO Guidance on Face Masks Changes

Surprising New Guidance from the WHO The WHO guidance on face masks for COVID-19 has changed to include the recommendation that the general public use fabric masks in public settings where physical distancing can’t be achieved and provides specific guidance on mask layers and materials. According to the World Health Organization (WHO), the ideal fabric […]

Fabric Face Masks: Cleaning and Disinfection

Reusable fabric masks should be cleaned and/or disinfected before each use to reduce risks associated with COVID-19 AND other potentially infectious microorganisms (e.g. bacteria, viruses, and fungi). Although the general principles of mask cleaning and disinfection are the same for most fabric masks, details will vary depending on specific mask designs, features, and materials. These […]

A Breathable Combination: An N95 plus a NWPP Mask Cover

As a result of the COVID-19 pandemic, there are global shortages of N95 respirators resulting in large scale adoption of procedures and policies for the extended use and re-use of N95 respirators. In this post we do a deeper dive into the quantitative breathability data for the MakerMask: Cover, a breathable N95 mask cover. The […]
