BARDA/NIOSH/NIST Phase 2 Finalist!

Flo Mask Pro was selected by BARDA, NIOSH, and NIST as an innovative mask, one of 10 finalists in the country. This recognition was given on March 2022, with the competition concluding later this year.

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.

Two filter options for all your needs.

Pro Filter

Utilizing next generation filtration technology, our Pro Filter line has been tested to filter over 99% of sub-micron particles for when you need the very best we offer.

Each Pro Filter is rated for up to 40 hours of use*.

Everyday Filter

Sometimes, breathability is just as important. Our Everyday Filter line offers nearly 3x the breathability, while still achieving 95-99% filtration efficiency, allowing you to go about your daily activities with confidence.

Each Everyday Filter is rated for up to 20 hours of use*.
