How It Works

Our sun is roughly 94 million miles from our planet.  The UV rays emitted by the sun take roughly 8 minutes to get to our planet’s surface, where even at a distance of 94 million miles, they can partially disinfect surfaces.  

The virus that causes Covid-19, for example, can be destroyed by outdoor UV light from the sun in just a matter of minutes, with proper exposure. This is astonishing considering the distance involved, but is a testament to the tremendous efficacy of the powerful UV spectrum for pathogen control.  We are also well aware of the tremendous skin damage caused by exposure to the sun’s UV rays. 

While we are not able to bring the sun indoors into your business, we can replicate the sun’s powerful UV spectrum indoors, with highly-advanced xenon lighting fixtures that utilize UV A, B and C spectrum to effectively neutralize pathogens (viruses, germs, bacteria and mold), on surfaces and in the air.

How Does UV Light Kill Germs?

Over 140 years ago Downes & Blunt discovered the antibacterial effects of sunlight. They determined that shorter wavelengths of the solar spectrum were more effective at neutralizing bacteria. It is now widely known that there are substantial germicidal and anti-bacterial effects from UV-C, UV-B, and UV-A light spectrums.

Germ-killing Light Targets the DNA & RNA of Microbes

DNA & RNA is the genetic material that makes up all living organisms, controlling their growth, development, functioning and reproduction. UV light produces electromagnetic energy that can destroy the ability of microorganisms to reproduce by causing photo-chemical reactions in nucleic acids (DNA & RNA). The ultraviolet energy triggers the formation of specific thymine or cytosine dimers in DNA and uracil dimers in RNA, which causes inactivation of microbes by causing mutations and/or cell death and failure to reproduce.

Germ-killing Light Targets the DNA & RNA of Microbes

Puro’s Helo and Sentry product lines, powered by Violet Defense technology, represent a significant breakthrough in germicidal protection for the world. The Puro™ solution uses a powerful, broad-spectrum light, including germicidal UV-C, UV-B and anti-bacterial UV-A to optimize their germ-killing efficiency.

UV-C is most traditionally referred to as germicidal UV with the ability to kill bacteria, viruses, mold, and fungus.

UV-A and UV-B light causes oxidation proteins and lipids causing cell death.

Broad band UV lamps have also been shown to inhibit photo-reactivation, the process that can result in self-repair of damaged microbes.
