Wellness and aromatherapy products aren't required to undergo the kind of chemical analysis that medical devices undergo. We commissioned one anyway, because "natural" is not a synonym for "tested," and we wanted hard numbers — for ourselves, for our customers, and for retail partners who needed to see them.
In early 2026, an independent research institute in the Netherlands ran a compositional analysis of Lio Minty Magic under controlled laboratory conditions. The procedure simulated four days of normal use, captured the full inhaled airflow, and identified every chemical compound present using gas chromatography–mass spectrometry (GC-MS). The protocol was run in triplicate.
The compounds identified were then measured against published European exposure thresholds — the same reference values used by occupational health regulators across the EU.
Every threshold cited below is a publicly available European regulatory reference. Nothing here is internal Lio data.
We're transparent about what this work covered. The analysis measured the chemical composition of what comes out of a Lio core under normal use, and compared it against published European exposure thresholds. It did not assess long-term health outcomes, and it does not — and cannot — declare Lio "safe" in absolute terms. No single piece of chemical analysis can answer that question for any inhaled product, including the air in most cities.
What it does say: under controlled laboratory measurement, the compounds we deliver fall well below the thresholds European regulators use to assess inhalation safety in occupational settings — which are themselves conservative by design.
Lio is a wellness and aromatherapy product, not a medical device. We make no medical claims. If you have a respiratory condition, are pregnant or nursing, or are unsure whether Lio is right for you, consult a physician before using it.
Lio is a wellness and aromatherapy device. Statements on this page have not been evaluated by any medical regulatory authority. Lio is not intended to diagnose, treat, cure, or prevent any disease, and is not a medical or smoking cessation device. The studies referenced on these pages describe the broader body of research on sensorimotor and olfactory craving science, and do not constitute clinical evidence regarding Lio specifically. Independent laboratory analysis referenced on these pages measured chemical composition against published European exposure thresholds and does not constitute a clinical safety determination.
