220-bed regional hospital
A 220-bed acute-care hospital retrofitted 340 patient-facing fixtures to run continuous UV-C air purification during occupied hours.

The challenge
Between HVAC cycles, air in patient rooms, corridors, and waiting areas stagnated for 20–40 minutes at a time. Existing HEPA carts were disruptive, noisy, and only deployed reactively after known exposures.
The solution
SafeAirUV™ 2×4 troffers replaced existing LED panels across patient rooms, nurse stations, and corridors. Fixtures were installed department-by-department across four weekends with zero unit closures.
Outcomes
- Independent 90-day CFU sampling in patient rooms showed a 71% reduction in airborne bacterial counts vs. pre-install baseline.
- Sustained 6.2 air changes per hour in patient rooms, exceeding CDC's 6 ACH target for airborne isolation.
- Facilities team eliminated 60% of previously scheduled portable HEPA deployments.
- Zero UV-related patient or staff safety incidents in the first 12 months of operation.
“We finally have a disinfection layer that runs during patient hours — not just overnight. It's part of the building now, not a cart someone has to remember to wheel in.”
