PNOĒ 2.0: Self-Serve Breath Testing Mask Launches Oct 1

Why This Matters
Removing the staffing requirement could push clinical-grade metabolic testing into mass-market fitness retail.
Massachusetts-based PNOĒ will launch its PNOĒ 2.0 metabolic testing mask on October 1, 2026. The updated device lets users self-administer an 8-minute breath test without trained staff, measuring 23 biomarkers including VO₂ max, resting metabolic rate, and metabolic flexibility.
PNOĒ, headquartered in Malden, Massachusetts with operations in Athens, Greece, is launching the PNOĒ 2.0 on October 1. The wearable mask analyzes oxygen consumption and CO₂ exhalation to produce personalized advice on diet, training, and longevity. The defining upgrade from its predecessor: no trained operator required. CEO Apostolos Atsalakis describes the process as simply putting on the mask, pressing a button, and breathing for eight minutes. That shift matters commercially. The current device's dependency on trained staff limits deployment to clinical or staffed settings. A self-serve model opens potential channels including unstaffed gyms and pharmacies. The underlying science — metabolic testing via breath gas analysis — has existed for over a century and remains the gold standard for VO₂ max measurement. Traditionally, the equipment was bulky, expensive, and confined to sports labs and hospitals, making it accessible mainly to elite athletes and executive health programs. PNOĒ, now 10 years old, claims to deliver equivalent accuracy in a portable form, capturing 23 biomarkers. These include resting metabolic rate and metabolic flexibility — metrics Atsalakis argues blood tests cannot provide. The launch comes as VO₂ max has surged in public awareness, driven by longevity research linking cardiorespiratory fitness to lower mortality rates.
