The halimeter is a reliable and precise tool for objectively measuring halitosis (bad breath).

The use of a halimeter (often based on gas chromatography or sulfide sensors) is indeed recognized in dental practice for quantifying the volatile sulfur compounds responsible for odors. Studies, notably systematic reviews published in journals such as the 'Journal of Breath Research', confirm that these devices offer an objective measurement superior to self-assessment or olfactory testing by an examiner, which remain subjective. However, it is important to note that this tool measures chemical concentration but does not determine the underlying cause (hygiene, bacteria, digestive, or ENT health). While the technical precision is validated, the exaggeration lies in the idea that such a device is necessary for daily use, when it is primarily a clinical instrument. In summary, the tool is scientifically valid for its intended use, but remains a professional diagnostic solution rather than a common personal wellness accessory.
