Airmid’s research contributes to the growing evidence base around innovative indoor air quality solutions
We were delighted to see research conducted by Airmid Healthgroup scientists presented at the 6th International Congress on Health Innovation (INOVATEC 2025), held in Brasília, Brazil from 21–23 November 2025.
Dr. Paula Jaramillo presented a poster titled “Synergistic Effects of Low-level UV and Hydrogen Peroxide in Reducing Airborne Influenza A (H1N1)”, based on work carried out during her time with Airmid. The research was presented in a personal capacity following her time with the organisation, while she was visiting Brazil.The study was carried out alongside fellow Airmid Healthgroup scientists Arlo Bowe, Oliver C. Dsa, and Dr. Angela Southey
Exploring New Approaches to Airborne Virus Reduction
The study investigated a combined air decontamination approach using low-level ultraviolet (UV) light and hydrogen peroxide (H₂O₂). While each method has limited antiviral impact individually, the research explored how, when used together, they can generate reactive oxygen species capable of accelerating the breakdown of airborne viral particles.
Using a controlled environmental chamber, the team aerosolised Influenza A (H1N1) and measured viral RNA concentrations over time. The results demonstrated a significant reduction in airborne virus levels when the combined UV–H₂O₂ system was in operation, compared to natural decay observed in control conditions.
Notably, the system achieved reductions of over 95% within 50–60 minutes across multiple test runs, with no harmful ozone generation detected during the process.
Supporting Innovation in Indoor Air Quality
This work contributes to the growing body of research exploring how combined technologies may enhance strategies for managing airborne contaminants in indoor environments. As the importance of indoor air quality continues to gain global attention, studies like this help inform future approaches to reducing exposure to infectious agents.
At Airmid, we remain committed to advancing scientific understanding in this area through rigorous testing and research.
Acknowledging Paula’s Contribution
We were very pleased to have Paula represent this work at INOVATEC 2025. During her time at Airmid, she made a valuable contribution to our research programmes, particularly in microbiology and aerobiology.
We would like to thank her for her work and dedication, and we wish her every success in the next stage of her career.
