AIR Limited said a newly published, peer-reviewed study found significantly lower levels of indoor air pollutants from its OOKA electronic waterpipe and from e-cigarettes compared with conventional hookah and combustible cigarette use. The research, published in December 2025 in Contributions to Tobacco & Nicotine Research, was authored by cardiovascular researcher Dr. Ian M. Fearon and based on testing commissioned by AIR and conducted by Al Futtaim Element Materials Technology Dubai LLC in an unventilated facility.
According to the study, conventional charcoal-heated waterpipes and cigarettes generated the highest increases in carbon monoxide, formaldehyde, particulate matter (PM10 and PM2.5), and other toxicants. By contrast, AIR’s OOKA device, which does not use charcoal, produced negligible carbon monoxide and roughly 40% lower particulate matter than conventional hookah in single-user scenarios, while e-cigarettes produced the lowest particulate levels overall. In multi-occupant scenarios, elevated volatile organic compounds and polycyclic aromatic hydrocarbons were observed primarily during cigarette smoking.
AIR CEO Stuart Brazier said the findings support the view that electronic delivery systems may reduce secondhand exposure risks in indoor environments while maintaining social smoking traditions. The study comes as AIR prepares for a proposed business combination with Cantor Equity Partners III, which would take the company public on Nasdaq under the ticker “AIIR” in the first half of 2026, pending regulatory approvals.
