Breathable Masks: Testing Results

Key result: Quantitative testing shows that fabric masks constructed from spunbond nonwoven polypropylene (NWPP) and/or quilting cotton are breathable and can satisfy NIOSH criteria for breathability. Introduction: Breathable Masks Breathing isn’t optional, and as COVID continues and mask wearing becomes commonplace, we are becoming more aware of the air around us and every breath we […]

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 […]

This post contains the audio and transcripts of Dr. Songer’s Keynote Speech: “Masks Unmasked: A Look at the Science Behind Fabric […]

3 Easy DIY Mask Tests

In an ideal world, the safety and efficacy of all of the fabrics and materials used in handmade masks for COVID-19 would be tested using the same standards and facilities used by researchers and large manufacturers. Unfortunately, very few people have access to these resources. In this post we provide instructions for three easy DIY […]

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 […]

The Big Four: Criteria for Fabric Mask Materials for COVID

Ésta immersión profunda mira al criterio “Cuatro Grande” evaluado en evaluaciones preliminarias de materiales de máscaras comunitarias: cáracteristicas de los materiales, respirabilidad, repelencia al agua, y opcións para disinfección. Más especificamente, enfocamos en polipropileno no tejido (PPNT), que está usado comunmente para máscaras comerciales. A pesar de que PPNT ideal de grado médico no está disponible para uso comunitario, PPNT está disponible comunmente en diferentes pesos y grados para otros usos del hogar y/o otros propósitos comerciales, como bolsas reusables de compras. Aquí tomamos una mirada más profunda a los 4 criterio peliminares considerado cuando evaluando fuentes potenciales de PPNT.
