UV Effectiveness and Safety

The effectiveness of UV on inactivating or destroying microbes depends on the microorganism’s structure, size and resilience, in addition to the UV exposure parameters including duration of exposure, wavelength and intensity (see SCIENTIFIC SUPPORT).

UV-C (231-280nm) must be shielded from humans as it poses a carcinogenic safety risk. Continuous low doses of Far UV-C (200-230nm) have been studied and no human effects reported (see SCIENTIFIC SUPPORT).
