The Science

Learn about the science behind our germ-killing LED lights.

The Science


Vital Vio’s precise spectrum of light, created with our patented LED technology, initiates a photo-activation of porphyrin molecules found in microorganisms. This photo-activation leads to the production of Reactive Oxygen Species (ROS). In high doses, ROS cause irreparable damage to the cellular structure, which leads to bacterial cell death.

Bacteria Cell

Dead Cell

Vital Vio light shines on the bacterial cell and (photo)activates molecules within the cell.

Reactive Oxygen Species are produced in excess.

Build-up of Reactive Oxygen species is toxic and causes cellular damage.

The damage caused by the Reactive Oxygen species results in the death of the bacterial cell, rendering it harmless.

Vital Vio Delivers Continuous Protection in Two Powerful Modes.

Work, Live and Be Protected in Vital Vio White Light Mode

  • White Light
  • Antibacterial White Light

Turn It up with Eco-Mode

  • Kills bacteria with 2X dosage, but certified for use around people, pets and plants
  • Perfect for downtime or overnight cleaning
White Light Disinfection™

Vital Vio’s technology cleans every area of a room at all times, just at different rates based on distance. Laboratory and controlled room experiments show up to a 90% bacteria reduction in a treated environment for one day. In an actively used facility, statistically significant reductions can occur in a matter of weeks.



Chances are that your current cleaning solution allows for intervals of high bacteria growth; we call this intermittent cleaning. By installing our system you are able to continuously control bacteria to a decreased level.


Vital Vio has conducted several years of clinical research and continues to be committed to ongoing research. We have conducted microbiology tests in high-risk clinical environments and an expanding range of other settings. Case studies are available on request.
