We’re all trying to go the extra mile right now to stay safe and sanitary in the face of the global COVID-19 pandemic. These geology-inspired masks pass the 'candle test' (while wearing the mask, try to blow out a candle). The flame doesn't move, even without inserting an extra filter insert! However, you can add on a pair of PM2.5 filter to your order for an additional $2. Cover up with geo-printed face coverings and stay safe with a touch of science.
