Efficacy Testing & Infinite Shield

Nittany Solutions Group hired a leading environmental testing firm to evaluate the reduction efficacy of our Infinite Shield interface against a variety of organisms. These pathogens are common sources of HAIs (Healthcare-Associated Infections) and food borne illnesses.

Evaluated Organisms:

Escherichia coli (E. coli)

Staphylococcus aureus (MRSA)

Enterococcus faecalis (VRE)

Clostridioides difficile (C. diff)

Candida auris (C. auris)

Klebsiella pneumoniae (CRKP)

Pseudomonas aeruginosa (P. aeruginosa)

Streptococcus pyogenes

Approach Method:

Evaluation was conducted at two different exposure times. The organism samples were exposed to the energized Infinite Shield interface for two seconds or six seconds. This was replicated three times.

Conclusion:

At the 2 second exposure time, the average organism percent reduction and log reduction ranged from a low of 99.987% and 4.06 log reduction (P. aeruginosa) to a high of >99.9994% and >5.58 log reduction (S. Aureus or MRSA).

At the 6 second exposure time, the average organism percent reduction and log reduction ranged from a low of 99.9983% and 4.76 log reduction (E. coli) to a high of >99.9999% and >5.94 log reduction (S. Aureus or MRSA).

Pathogen Reduction Efficacy Results

 
 

Why Logarithmic Reduction?

  • Logarithmic (log) reduction is the standard used for quantifying disinfection by the EPA.

  • When speaking in terms of pathogen inactivation, log reduction is incredibly important because these organisms are numbered in the millions.

  • Therefore, pathogen reduction is calculated using a logarithmic scale, which stands for a 10-fold reduction in microbe count.

  • For reference, as compared to 2-log, 3-log is 10x more effective, 4-log is 100x more effective, and 5-log is 1,000x more effective.

Competitive Comparison

Following our independently validated efficacy results, it’s important to contextualize the performance of the Infinite Shield. When benchmarked against existing surface disinfection products—especially those used for shoe sole disinfection—the advantages of our technology become decisively clear.

Unmatched UV-C Disinfection Efficacy

Below is a comparison of pathogen reduction results between our Infinite Shield technology and two leading competitors who have UV-C Shoe Sole disinfection equipment in the market.

Please note that competitor exposure times are 6 seconds and 8 seconds whereas our Infinite Shield exposure times are 2 and 6 seconds.

In a fraction of the exposure time, the Infinite Shield is significantly more effective in reducing harmful pathogens.

 

Relative Effectiveness

The Infinite Shield performs 1000x and greater pathogen reduction, in less time.

 

Why Infinite Shield Stands Apart

Engineered for Performance

The exceptional performance of Infinite Shield is the result of multiple core engineering advantages:

  • Dense UV-C LED Array: Hundreds of solid-state emitters deliver consistent, uniform light distribution across the disinfection surface.

  • Optimized Wavelength & Emission: Our emitters produce the most effective germicidal wavelength, activate instantly, and avoid the warm-up times and fragility associated with low-pressure mercury lamps.

  • Durability & Longevity: With a lifespan 8–10 times greater than mercury lamps, our LEDs are built for continuous, high-volume use without performance degradation.

Designed for Versatility

Unlike bulky or fixed-purpose systems, Infinite Shield’s design is:

  • Modular and Scalable: Our disinfection cell arrangement can be customized to different dimensions and geometries—whether flat, sloped, or multiple surfaces—allowing for seamless integration across various environments.

  • Compact: The small form factor supports use in space-constrained areas or embedded into existing equipment infrastructure.

  • Application-Agnostic: Whether for shoe sole ingress control, conveyor belts, tray disinfection, or work surface sanitation, Infinite Shield can be tailored to fit the operational need.

 

infinite shield - a Disruptive Technology

The world’s first UV-C surface disinfection system engineered with precision digital shielding

  • A patented, safety breakthrough, the Infinite Shield prevents direct user exposure to UV-C light through intelligent, localized control.

  • A dense array of UV-C LEDs and optical sensors is embedded in our disinfection interface, positioned beneath the shoe. The system precisely detects the shoe’s outline and activates only the LEDs directly beneath it—ensuring targeted disinfection while maintaining user safety.

  • Enables safe deployment in high-traffic areas

  • Maintains full disinfection efficacy without sacrificing safety
