VirWall Keyboard Sanitizer KBS-1

Product Fact Sheet

Purpose of Product

To sanitize computer keyboards as a measure of preventing the spread of potentially pathogenic organisms

Reason for Development of Product

Jon Roberts and the KBS-1

Dr. John Roberts, inventor of the Keyboard Sanitizer, had never been as sick, as frequently, or for such long durations as when his son attended elementary school, a school with computer classrooms. In reading scientific journals to better understand how bacteria and viruses are transmitted, he learned that certain inanimate objects (i.e., computer keyboards) can become perfect homes for the growth of pathogenic microorganisms. Touching these objects transfers the bacteria from object (vector) to user, then from user to multiple objects as well as friends, classmates, co-workers and family. He notes that at the peak of the 2007-08 flu season, absenteeism in his office reached almost 50%. Dr. Roberts combined his skill as a photographic scientist, his engineering background and his familiarity with the electromagnetic spectrum to devise a solution. His efforts resulted in the development of the (product name) – a safe, simple and effective device to inactivate potential pathogens that lurk on keyboard surfaces and in the spaces between keys. “The germs I’m concerned about in an office or classroom on a day-to-day basis are the influenza virus, Norovirus, MRSA, and the common cold rhinovirus,” said Dr. Roberts. His KBS-1 can inactivate all of these microorganisms and more.

Principle of Action

Ultraviolet (UV) light causes molecular rearrangement of a microorganism’s DNA which prevents it from reproducing and therefore renders it microbiologically dead. The effectiveness of UV energy on microbial destruction is dependent upon intensity and time of exposure, and differs for each microorganism. The intensity of UV-C (short wavelength ultraviolet, 200 to 265 nanometers) light is measured in microwatts per square centimeter, and the time is measured in seconds; thus a dose is reported in units of micro-watt seconds per square centimeter. It has been determined that exposure of computer keyboards to the Keyboard Sanitizer for 45 seconds kills bacteria and inactivates viruses; two 30-second bursts will inactivate bacterial spores, as well.

Features and Benefits

  • UV lamp that emits 254 nm wavelengths at an intensity and for a duration demonstrated to kill bacteria and inactivate viruses
  • Designed to kill bacteria and inactivate viruses on upper and side surfaces of keyboards and in spaces between the keys
  • More reliable than disinfectant wipes, ethanol, or soap and water
    • The Keyboard Sanitizer delivers greater microbiological eradication at each use
    • The effectiveness of wipes, alcohol, or soap and water depends upon the thoroughness of each individual user, whereas the Keyboard Sanitizer delivers consistency of application and consistency of results.
  • Safety features include:
    • Shield to prevent fingers from touching UV lamp
    • Level sensors that shut the unit off automatically if it is not level, preventing its use as a “light wand” and making it impossible to look at the lamp during use.
  • Slot to accommodate laptop keyboard
  • Consistent, repeatable sanitizing cycles for consistent results. This is an advantage over wipes
  • Small footprint when stored on end
  • Two models available: one powered by wall outlet, one powered by rechargeable batteries
  • Negligible production of ozone (in contrast to UV lamps that emit shorter wavelengths)
  • Recently won the “Green” Yankee Inventor Expo award as an environmentally friendly alternative to liquid hand and surface disinfectants/wipes – which have been implicated in chemical pollution of water sources.
