Air Disinfection

UVC solutions can help reduce viruses in air. Based on testing using a bacteriophage MS2 model system, Current predicts that 365DisInFx™ UVC technology will provide 99% inactivation with less than 6 hours of exposure for seasonal coronaviruses, including SARS-CoV-2, the virus that is known to cause COVID-19, when used as directed.1

Surface Disinfection

UVA solutions can help reduce bacteria and fungi on surfaces. Our in vitro testing with eight hours of exposure has shown significant reductions in common pathogens associated with hospital-acquired infections (HAIs), such as MRSA, Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Acinetobacter baumannii, Pseudomonas aeruginosa, Candida albicans and auris.2

Make an Informed Decision

  • UV radiation can pose a risk of personal injury. Overexposure can result in damage to eyes and bare skin. To reduce risk of overexposure, equipment must be installed in accordance with site planning and application recommendations.
  • UV solutions are intended for common high traffic spaces and not recommended for dwellings or home use.
  • Installation of the devices should be performed by qualified professionals as detailed in Current’s installation guide
  • To allow for occupancy, Current products comply with IEC 62471 Photobiological Safety for Lamps and Lamp Systems standard and American Conference of American Hygienists (ACGIH®) TLVs®
  • Current's UV products are meant to be used in conjunction with other protective measures like manual cleaning and the use of proper PPE. They are not a substitute for other measures.
  • Current products are not intended to be used as a medical devices.
  • When combining two or more UV solutions, whether from GE Current, a Daintree company and/or other manufacturers, please consult a trained product application representative to ensure the total irradiance (UV dose) does not exceed recommended human exposure limits. To the extent UV solutions are combined, it may affect the deactivation rates. To the extent UV solutions are combined, it may impact inactivation rates.

1. UVC Testing, Lab Results & Notes back to top

GE Current, a Daintree company, has completed in-situation testing of its 365DisInFx™ UVC disinfection technology LPU series devices utilizing the aerosolized virus, bacteriophage MS2.

This benchmark testing with the bacteriophage MS2 resulted in 88% inactivation of the aerosolized virus in a 10-by-10-by-8-foot room within 4 hours. Applying the test results to 24-hour continuous operation of the 365DisInFx™ LPU would result in 44% inactivation of bacteriophage MS2 in 2 hours.

Bacteriophage MS2 is a nonenveloped virus that is commonly used as a surrogate for viruses that are pathogenic to humans. It is particularly useful as a surrogate because published scientific testing and literature supports that bacteriophage MS2 is more resistant to UVC than certain enveloped viruses such as coronaviruses and influenza.

Based on photobiological science and mathematical modeling, Current anticipates equivalent or better results for seasonal coronaviruses and SARS-CoV-2. When properly installed and configured for the space, continuous operation of the 365DisInFx™ LPU should provide 50% inactivation in the first hour of exposure, 90% inactivation (1 log) in 3 hours or less of exposure, and 99% inactivation (2 log) in 6 hours or less of exposure. Current continues to conduct additional confirmatory testing.

 

2. UVA Testing, Lab Results & Notes back to top

365DisInFx™ UVA disinfection technology was tested using in-vitro methods as described in detail in Citations 1 & 2 below (Livingston, Kvam) which resulted in 99.7% reduction in MRSA on surfaces exposed to 3W/m2 of 365nm UVA over a single 8-hour period. Results of this testing demonstrated significant reduction over a similar exposure period of certain common pathogens including MRSA, Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Acinetobacter baumannii, Pseudomonas aeruginosa, Candida albicans and auris, associated with Hospital Acquired Infections (HAIs). Photobiological science and mathematical modeling enables us to calculate expected inactivation rates for 24-hour continuous operation of the 365DisInFx™ UVA technology.
