PNOĒ Launches Self-Serve Metabolic Testing Mask for Gyms and Wellness Centres

PNOĒ is preparing to launch a self-serve version of its metabolic testing system that lets users measure breathing-related fitness markers without a trained operator.

The Massachusetts-based company plans to launch PNOĒ 2.0 on October 1. Users can put on the mask, start the test, and breathe normally for about eight minutes while the device measures oxygen consumption and carbon dioxide output.

PNOĒ says the system analyses 23 biomarkers, including VO₂ max, resting metabolic rate and metabolic flexibility, then uses software to turn those measurements into recommendations related to training, nutrition and wellness.

Self-service could expand where PNOĒ is used

The company’s current device requires a trained operator, limiting deployment to locations with qualified staff. CEO and co-founder Apostolos Atsalakis said the self-service design could make metabolic testing practical in more gyms and potentially pharmacies.

The new device is smaller, uses fewer parts and was designed to be more reliable than its predecessor. Its electronics can also detach from the silicone mask and straps, allowing multiple people to share the hardware while keeping individual masks.

Metabolic testing has been used for decades to measure VO₂ max and other indicators of how the body produces energy. Still, traditional systems are typically expensive and concentrated in hospitals, sports laboratories and specialist facilities.

PNOĒ remains a wellness product, not a medical device

The U.S. Food and Drug Administration does not clear PNOĒ and does not provide medical recommendations. Atsalakis described it as a wellness tool rather than a diagnostic device.

The company believes its growing breath-data set could eventually help identify health problems, but Atsalakis said full diagnostic capabilities remain years away and would require regulatory approval.

PNOĒ sells its technology to businesses rather than directly to consumers. Customers include Equinox, Four Seasons, Red Bull, the NBA, Mount Sinai Health System and Restore Hyper Wellness.

Businesses pay subscriptions ranging from about $400 to more than $1,000 per month for hardware, software, training and marketing support. About 85% of PNOĒ’s business currently comes from the U.S.

The company has raised about $22 million, including a recently closed $11 million round, employs 110 people and says it has recently become profitable while growing more than 100% annually. PNOĒ plans to pursue a Series B financing round within the next six to 12 months.
