3D Printed frames to enable reuse and improve the fit of N95 and KN95 respirators.

ABSTRACT:

Background

In response to supply shortages during the COVID-19 pandemic, N95 filtering facepiece respirators (FFRs or "masks"), which are typically single-use devices in healthcare settings, are routinely being used for prolonged periods and in some cases decontaminated under "reuse" and "extended use" policies. However, the reusability of N95 masks is often limited by degradation or breakage of elastic head bands and issues with mask fit after repeated use. The purpose of this study was to develop a frame for N95 masks, using readily available materials and 3D printing, which could replace defective or broken bands and improve fit.

Results

An iterative design process yielded a mask frame consisting of two 3D-printed side pieces, malleable wire links that users press against
