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 nonwoven polypropylene (NWPP) in homemade masks due to NWPP’s inherent hydrophobicity, or water resistance. Thanks to community contributions, we were able to put reclaimed NWPP to the test […]

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 […]
