The rapid spread of COVID‐19 has led to personal protective equipment (PPE) shortage worldwide 1,2. Recently, the adaptation of commercially available modified full‐faced snorkel masks (mFFSMs) has been proposed as an alternative of PPE shortage. mFFSMs were adapted and used by health care workers during the COVID‐19 crisis 3. An mFFSM is composed of an off‐the‐shelf snorkel mask, a custom adapter (three‐dimensional‐printed with a custom print file that sourced attributes from the designs found at Pneumask and OceanReef.), and a filter cartridge (Figure1‐a).
