Flo Mask Pro
BARDA/NIOSH/NIST 2021 Phase 1 Winner & 2022 Phase 2 Runner Up!
Flo Mask Pro was selected by BARDA, NIOSH, and NIST as an innovative mask, winning Phase 1 of the mask competition and coming in 2nd place for Phase 2.
Inclusive design with two sizes.
Size 1: Low/Med Nose Bridge
A lower nose bridge is common for those of Asian, Pacific Islander, and African descent. We've developed a size with a more shallow nose curvature to ensure a perfect fit.
Size 2: Med/High Nose Bridge
A higher nose bridge is common for those of European and Hispanic descent. Our larger size has a more generous curvature for those with a taller bridge.

A proper fit.
A unique shape for 90%+ of adults
Our mask dimensions are sized to fit over 90% of the world's adult population. Please verify your nose bridge (starting just below the bony part) to chin (center) distance is at least 3 inches.
The ~10% outliers
Flo Mask Pro may be challenged to fit those with: Roman shaped nose bridges, sharp/narrow nose bridges, narrow face, or small face size (short nose to chin). Note we do not allow returns as we do not sell used items, so please check your measurements prior to ordering.
