The Types segment differentiates the market by device architecture and usage modality. Portable inhalers, characterized by battery operation and compact form factors, dominate the product mix, delivering roughly 55 % of unit volume due to their suitability for home and on‑the‑go consumers. Desktop units, equipped with higher‑capacity generators and integrated monitoring interfaces, account for about 25 % of sales, primarily serving clinical environments where continuous dosing is required. Wearable designs—lightweight masks or neck‑band generators—are emerging, contributing an estimated 15 % as athletes and tech‑savvy users seek hands‑free operation. Integrated systems that combine hydrogen generation with ancillary therapies (e.g., ozone, UV) hold a modest 5 % share, reflecting early‑stage adoption in specialized treatment centers. Each type’s market contribution aligns with functional requirements, price sensitivity, and regulatory pathways, providing a granular view of the overall market taxonomy.
