Can far-UVC protect a whole hospital ward?

Challenge

Hospital wards — especially a COVID ward — face relentless infection pressure across patient rooms and shared staff spaces.

Approach

UV222™ far-UVC running autonomously since 2021 across the COVID ward, staff rooms, and common areas.

Result

A ~70% reduction in surface bioburden — continuous protection with no change to the ward’s workflow.

The Challenge

Infection pressure across an active ward

A busy hospital ward is a web of shared spaces — patient rooms, staff rooms, and common areas — all under constant contamination pressure.

During the pandemic that pressure intensified on the COVID ward. Cleaning is essential, but it can’t run continuously across every room while the ward is in use.

The Approach

Continuous far-UVC, ward-wide

Kolding Hospital deployed UV222™ far-UVC across the COVID ward, staff rooms, and common areas.

The human-safe 222 nm light has run autonomously since 2021, continuously disinfecting air and surfaces in occupied rooms — without disrupting patients, staff, or routine.

The Result

~70% less surface bioburden

Surface bioburden across the ward fell by roughly 70%.

Sustained over years of autonomous operation, it adds a constant layer of infection prevention across the spaces where patients and staff spend their days.

“~70% less surface bioburden — autonomous protection across an active ward since 2021.”
