Case Study: DNO Purification at Massey Children’s Hospital

Massey Children’s Hospital cares for some of the most vulnerable patients in Lagos — infants and young children whose developing lungs are especially sensitive to airborne particulate matter, pathogens and volatile organic compounds. When the facilities team approached Healthy Air Technology Nigeria, their goal was clear: measurable, medical-grade air quality across critical care areas, backed by documentation they could trust.

We began with a free on-site air quality assessment. Our consultants profiled each space — measuring PM1.0, PM2.5, PM10, CO₂, CO, NO₂, SO₂, formaldehyde and VOCs — to understand exactly where pollutants were concentrating and why. The audit revealed elevated particulate levels in wards during peak visiting hours and inconsistent air exchange in enclosed treatment rooms.

Based on the findings, we designed a tailored deployment of D-Orbital Nano Oxide (DNO) purification units — the Oxford University-developed catalyst technology that neutralises pollutants at 99.99% efficacy rather than simply trapping them. Units were sized and positioned for each clinical area, from the ICU to general wards, ensuring continuous coverage without disrupting hospital workflows.

Every unit was paired with connected sensors streaming live data to a cloud dashboard, so the clinical and facilities teams can see air quality in real time and receive automated alerts if any pollutant spikes above threshold. A managed service agreement covers scheduled filter changes, sensor calibration, performance optimisation and 24/7 support — keeping the systems performing at their peak with zero effort from hospital staff.

The result: documented, sustained improvements in indoor air quality across critical care areas, a clear audit trail for compliance, and — most importantly — total peace of mind for clinical staff and the families who trust Massey with their children’s health.
