The article contains specific instructions on how to construct a handmade mask, which was tested against an aerosol challenge with some measurable benefit. The authors of this brief study admit that there are problems with the masks' overall efficacy and risk of improper construction or use. Since cottage industries for masks may arise during a pandemic, it is crucial to list possible effective alternatives and limitations in their use. One reviewer suggested that if people will be inclined to use any protection they can acquire during a pandemic, it may be good practice to test possible alternatives prior to a health emergency. This practice may represent an alternative to using respirators or surgical masks that may be in short supply during a pandemic, and it may stimulate exploration of other PPE possibilities.
