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 […]

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 […]
