Purify-One provides industry-leading Ultraviolet (UV) Germicidal devices clinically
proven to disinfect and eliminate up to 99.9% of germs, bacteria, and viruses
The SCIENCE
Why UV Disinfecting?
Harmful germs and bacteria are everywhere. Now more than ever it’s important to ensure that the space around us is healthy and safe. Sterilizing hand gels, disinfectant sprays, and sanitizing wipes are not enough to ensure a healthy environment.
Many bacteria and viruses are heat, cold, and drug-resistant. They are not UV resistant!
Utilizing UV-C at 270-280 nanometers (nm) and UV-A at 380-405 nm, Purify-One devices damage the DNA and RNA in bacteria and viruses rendering them harmless.
With high powered, proprietary LED light technology, Purify-One UV devices allow you to disinfect up to 10x faster than most fluorescent UV devices and is 2x more powerful than other LED UV devices on the market.
What is UV Light?
Ultraviolet (UV) light is a component of the electromagnetic spectrum that falls in the region between visible light and X-Rays. This invisible radiation includes the wavelength range of 100 nm to 400 nm.
UV light can be further subdivided and categorized into four separate regions:
- 100 to 200 nm:
Far UV – these wavelengths only propagate in a vacuum - 200 to 280 nm:
UV-C – useful for disinfection and sensing - 280 nm to 315 nm:
UV-B – useful for disinfection, curing, tanning, and medical applications - 315 nm to 400 nm:
UV-A (or “near UV”) – useful for disinfection, medical applications, printing, curing, lithography, and sensing
Most Natural UV light is generated by the sun with about ten percent of sunlight being UV and only 3 to 4 percent penetrating the atmosphere to reach the ground. Of the UV radiation that reaches the earth, 95 percent is UV-A and five percent is UV-B.
No measurable UV-C from the sun reaches the earth’s surface.
Because of the spectral sensitivity of DNA, the UV-C region demonstrates significant germicidal properties.
The Research
As evident by multiple research studies and reports, when biological organisms are exposed to deep UV light in the range of 200nm to 300nm it is absorbed by DNA, RNA, and proteins.
How this affects bacteria and viruses:
- Absorption by proteins can lead to the rupture of cell walls and the death of the organism.
- Absorption by DNA or RNA (specifically by the thymine bases) is known to cause inactivation of the DNA or RNA double helix strands through the formation of thymine dimers. If enough of these dimers are created in DNA, the DNA replication process is disrupted and the cell cannot replicate.
It is widely accepted that It is not necessary to kill pathogens with UV light, but rather apply enough UV light to prevent the organism from replicating. The three main types of UV rays are UV-A, UV-B, and UV-C. Because UV-C rays have the shortest wavelength, and therefore highest energy.
UV-C has been proven to kill strands of coronavirus (below are notable research studies demonstrating the effectiveness of UV-C light on SARS and MERS).
