UV-Clean unit demonstrated its ability to eliminate 99.99% of C. diff and MRSA

* Proximity-Systems-UV.jpgProximity Systems has released the results from recent NSF International testing that demonstrates the efficacy of the company's UV light disinfection unit, UV-Clean.

Emitting low-intensity ultraviolet C light, UV-Clean eliminates 99.99% of Methicillin-resistant Staphylococcus aureus (MRSA) and Clostridioides difficile (C. diff) endospores from keyboards.

"NSF International is a leading provider of public health & safety-based risk management solutions," says Proximity Systems' vice president of business development & senior care, Steve Reinecke.

"Its independent test of UV-Clean took place in an accredited, state-of-the-art lab with robust instrumentation and technologies and was conducted by highly experienced personnel. For those reasons, we're extremely confident in the results."

As part of the test, different keyboard keys were inoculated with C. diff and MRSA before being exposed to UVC light via the UV-Clean unit. Multiple exposure times were evaluated also. After post-swabbing and subsequent incubation, the following reductions were calculated and reported: There was a 91.1% reduction in C. diff after 10 minutes of UVC exposure; there was a 99.996% reduction in C. diff after 30 minutes of UVC exposure; there was a 99.996% reduction in MRSA after 10 minutes of UVC exposure; and there was a 99.998% reduction in MRSA after 15 minutes of UVC exposure.

Proximity Systems' CEO Jeremy Goza is excited about the successful testing.

"We are really pleased with how the testing was conducted and the results that were reported," he says. "These tests validated what we already knew about our product, that UV-Clean is effective at killing harmful pathogens found on high touch surfaces."

The clinical testing facilitated a common scenario at healthcare facilities across the world where infection-causing pathogens are transmitted by the hands of healthcare works from high touch surfaces like keyboards, workstations on wheels or portable medical equipment.

"Patients are at a higher risk to acquire a hospital acquired infection," says Steve Reinecke. "The NSF International testing proved Proximity's disinfection device UV-Clean is effective at eliminating bacteria, making it the right complement to existing cleaning and hand hygiene protocols."
