Urban Sun

World's first URBAN SUN cleans public spaces of the coronavirus for better human gatherings.

URBAN SUN is s a symbol of hope and shines a large circle of this far-UVC light into public spaces, sanitising those spaces of the coronavirus. It acts as an additional layer of protection to current government rules. URBAN SUN aims to inspire hope. It combats the negative impact of social isolation.

URBAN SUN is created by Roosegaarde’s team, along with external experts and scientists from the Netherlands, the US, Japan, and Italy. The URBAN SUN’s far-UVC light source is measured and calibrated by the Dutch National Metrology Institute VSL. URBAN SUN meets the International Commission on Non-Ionizing Radiation Protection (ICNIRP) safety standards.

The science is based on multiple peer-reviewed journal articles authored by scientists from Columbia University and Hiroshima University. The research shows that specific ultraviolet light (far-UVC) with the wavelength of 222nm can reduce the presence of viruses, including various strains of coronavirus up to 99.9%. Even though traditional 254nm UV light is harmful, this specific light of 222nm is considered safe for both people and animals.
