As you all know, everyone is in a mad DIY mask rush right now as it has become an official recommendation. Some have been searching for the best materials, and some of them have been found to be great filters. However, these non-standard mask materials are also not tested and evaluated for use as a respirator, where inhalation is a major consideration. Even worse, it is typical for hazardous chemicals like formaldehyde to be used in these classes of textiles (e.g. non-woven) as a binder, yet disclosure of levels of formaldehyde are not required by default for textiles, and laws limiting those levels are based on intended use (shop towels for example wouldn't be strictly regulated).
I'm curious about peoples thoughts; how can best incorporate proper caution and safety evaluation into the national efforts worldwide to prevent harm? It seems to be a missing part of the grassroots emergency effort.
