PNOE launches new face mask for self-serve breath testing
PNOE is launching a redesigned breath-testing face mask, PNOĒ 2.0, on October 1. The device enables self-administered metabolic testing, eliminating the need for trained operators.

PNOE, a Malden, Massachusetts-based startup, will launch its redesigned breath-testing face mask, PNOĒ 2.0, on October 1. The new version allows users to perform metabolic tests themselves, akin to lab-grade analysis, without requiring trained personnel.
The previous PNOE device necessitated a trained operator, which limited its deployment. The self-serve capability could open avenues for its use in fitness centers and potentially pharmacies. Users can reportedly complete the test by wearing the mask, sitting down, and breathing for eight minutes.
The underlying science of metabolic testing, which analyzes respiratory gases to gauge energy production, has been established for over a century. It has long been considered the gold standard for measuring VO₂ max, a key indicator of cardiorespiratory fitness. However, these tests historically relied on large and expensive equipment.
The PNOĒ 2.0 aims to democratize this advanced analysis. The company, with operations in both the US and Greece, anticipates the new model will broaden access for individuals in the health and fitness sectors.
