This or That: Kiosk Disinfecting Options

One of the many challenges we face today is the spreading of bacteria and infectious diseases. Contaminated touchpoints are everywhere. While medical facilities are especially prone to hosting pathogens – considering their primary function is: treating sick people – quick-service restaurants (QSRs) like McDonald’s , and even building lobbies with visitor kiosks present similar infection risks.

So, what should we do about it?

Well, the United States Environmental Protection Agency (EPA) published its benchmark for sanitization stating: “A device or solution must kill 99.9% of all pathogens on a visibly clean surface within 30 seconds for it to be considered sanitized.” Simply periodically wiping down the kiosk touch screen is not enough to satisfy the EPA disinfecting standard. So this leaves kiosk owners with two viable options to protect their users: either cover the touchscreen with a topical coating, or clean and sanitize it (and all the surrounding input devices) with UV-C light.

While technologies such as antimicrobial coatings or chemical wash solutions tend to be generally effective, they tend to become less effective over time, even if the coating is baked on. Typically, silver, copper or titanium oxides are used as a coating on the surface. As the surface is touched periodically over time, it can lose up to 30% of its antimicrobial ability. Chemical-based solutions tend to have higher operating costs associated with them and can have intermittent effectiveness based on environment. These treatments can be limited in functionality. Titanium oxide for example, requires light exposure to function, so depending on the ambient light source and strength, it’s possible that solution may not always work at full strength.

Which brings us to our next option…

A UV-C disinfecting solution meets the EPA requirements with “time to sanitation” ranging from 4.25 second for Shigella Flexneri – Dysentery to 19.25 seconds to kill Staphylococcus lacti. Here are some reasons the disinfecting UV-C blue light option outshines the other disinfecting options:

Effectiveness – We get it, you want something that works. Destroying 99.99% of microorganisms is a non-negotiable. And this solution does just that. Not only does it disinfect the touch screen, but also the surrounding equipment as well. Not an option with a chemical screen treatment.

Ingredients – Not all disinfecting solutions need to be chemical-heavy and pose a threat to the environment. A disinfecting option like a UV-C light is chemical-free and emits no by-products and is environmentally friendly..

Simplicity – This simple solution will work regardless of ambient light. After installation it works 24/7/365 with only a bulb replacement every 17,000+ hours, or about every other year.

Fast – The kiosk touchscreen and the surrounding equipment is germ-free in seconds! Every time, and after every use.

Proven – UV-C has been used in water purification systems since the 1930’s, in disaster remediation since the 1950’s and in hospitals to clean ER’s and OR’s for years. Now it is becoming the disinfectant of choice in public applications.

Affordable – Because a disinfecting light solution doesn’t require any input or extensive maintenance, organizations will benefit from the low operating cost of the technology. Connect the kiosk to power and you’re all set!

When considering disinfecting options, it’s clear which solution shines the brightest. A UV-C light solution works regardless of ambient light availability, has no harsh chemical residue, does not diminish effectiveness over time and offers proven, reliable results. It is the best option for kiosk touchscreen disinfecting.
