Results from a study published in the Journal of Ecotoxicology and Environmental Safety in May have indicated that masks pose significant risks to wearers due to toxins emitted by the tight-fitting face coverings.
“Based on our findings, we suggest that prior to wearing a KF94 mask, each product should be opened and not worn for at least 30 min, thereby reducing total VOC concentrations to levels that will not impair human health,” the authors concluded.
