A quick Google search will reveal a vast listing of videos that depict different ways that one might construct a Do-It-Yourself Mask for protection during the current pandemic. The quality of the designs varies widely and in almost all cases, no testing was conducted to evaluate the filtering efficiency of the proposed filter material or fit testing to evaluate the effectiveness of the seal around one’s facial orifices.
This page has been developed to share ideas related to Do-It-Yourself Masks in this time of growing urgent need. In the video below, EnMed Vice Dean, Dr. John C. Criscione describes how one might make a Do-It-Yourself mask. He offers information regarding different DIY options, including some widely available 3D Printable designs, and he describes some of the testing that should be pursued to evaluate these designs.
