What is UV-C

Shorter the UV wavelength the better

Most natural Ultraviolet (UV) light is generated by the sun with only 3%- 4% penetrating the earth’s atmosphere to reach the ground. Of the UV light that reaches the earth, 95% is UV-A and 5% is UV-B. No measurable UV-C from the sun reaches the earth’s surface as the atmosphere blocks UV-C light. When it comes to disinfecting pathogens UV-C light is the most effective at doing so. UV-C light refers to a specific section of the Ultraviolet spectrum which has the shortest wavelength (100nm-280nm). At Hunter UV we produce UV-C light at 253.7nm. UV-C light at this wavelength has a unique ability to denature and disinfect pathogens due to its shorter wavelength and pathogens having no natural protection to its effects.

how UV-C kills pathogens 

Destroying Pathogens at their core

When biological organisms, such as viruses, bacteria, spores and fungi, are exposed to UV-C light their DNA, RNA, and proteins absorb the energy. Absorption by proteins leads to rupturing of the cell walls and the death of the organism. Absorption by DNA or RNA causes inactivation of the DNA or RNA double helix strands through the formation of thymine dimers. When enough of these dimers are created in the DNA or RNA, the replication process is disrupted, and the cell can no longer replicate. This renders the organism non-infectious and not a threat to human health.

UV-C DOSage 

stronger and longer the Does, The better

UV light dosage refers to the amount of UV radiation an organism is exposed to. Each organism has its own dosage requirement to achieve a level of disinfection. This is often shown as (x)mJ/cm2. The variables within the environment to achieve a specific UV light dosage are the intensity of UV radiation, exposure time and the distance from the UV-C source. A number of biological studies have produced widely accepted typical UV dose requirements for most common target microbes.

Log Reduction-3


Higher the log less of the pathogen

Disinfection is measured by Log Reduction. Log Reduction is a simple mathematical term used to express the relative number of live microbes eliminated by disinfection. These are often expressed from Log 1 (90%) to Log 6 (99.9999%) and show the level of disinfection achieved. The higher the log the less of the pathogen remains.

Backed By Scientific Data And Research 

The T-1000 is backed by independently conducted research and studies showcasing its ability to disinfect pathogens and to lower HCAI’s. This data shows healthcare facilities increase operational performance, lower costs and prevent patient infections.
