Simple Covid-19 Coffee Filter Mask

thingiverse

Simple mask design utilizing Coffee Filters as the main component. Alternative options include using other types of filter paper or materials according to preference. The pores in standard Coffee Filter paper measure potentially large at more than 20 microns. Two filters are used in this design, with the inner ring serving as a means to secure them in place by folding them back into the mask. Users are encouraged to bring their own filter paper and elastic for assembly. It is possible that the printed size of the mask will need to be scaled up or down to fit individual faces, given that measurements are provided in inches. If this design fails to provide adequate protection, it can still be repurposed as a pour-over device.
