Mask Filtration and Breathability: Key Findings from the UBC Study

MakerMask collaborated with the Energy and Aerosols Laboratory at the University of British Columbia (UBC) to explore filtration and breathability of nonwoven and woven fabrics for reusable masks before and after washing. This post summarizes the key findings. See the paper for details: https://doi.org/10.4209/aaqr.220044  Motivation Although mask mandates have been rescinded, washable masks remain widely […]

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 […]
