Synexis' DHP Featured in AJIC in Long-Term Care Study

FOR IMMEDIATE RELEASE

Synexis Highlights New Findings on Dry Hydrogen Peroxide (DHP®) Technology’s Role in Reducing COVID-19 Transmission in Long-Term Care

Overland Park, Kan. – May 2, 2025 – Synexis LLC, a pioneer in continuous air and surface microbial reduction, announces publication of an independent peer-reviewed study indicating that its Dry Hydrogen Peroxide (DHP) technology may lower the risk of airborne disease transmission in healthcare settings. The findings, published in a recent article in the American Journal of Infection Control, highlight a long-term care facility’s experience deploying Synexis devices to enhance standard cleaning and disinfection practices.

The study observed a COVID-19 outbreak in three units of a long-term care facility. Two of the units—referred to as “Memory Lane” and “E-Unit”—had Synexis devices in place, while the third, “A-Unit,” did not. Despite comparable staffing, ventilation, and cleaning protocols, the two units with continuous DHP experienced substantially lower resident infection rates than the unit without the devices.

Key Findings at a Glance:

  • In A-Unit (without DHP), two-thirds of residents tested positive for COVID-19 (66.67% attack rate).
  • In Memory Lane (with DHP), no residents tested positive (0.00% attack rate) despite sharing staff with A-unit (0.00% attack rate).
  • In E-Unit (with DHP), only two residents tested positive (13.33% attack rate), and no additional cases occurred following those two infections.

Synexis’ patented DHP technology continuously reduces the presence of viruses, bacteria, mold, and volatile organic compounds (VOCs) in occupied spaces, providing a proactive approach to improving indoor air and surface quality.  This innovative solution operates 24/7, offering continuous microbial reduction in real-time, without requiring staff to operate or monitor devices.

 

Synexis technology has been evaluated in 13 healthcare-related peer-reviewed studies, with results consistently demonstrating efficacy across a range of healthcare settings and microbes.  While this study reports reduced transmission of COVID-19 in a long-term care facility, broader data demonstrates significant potential benefits for healthcare operations serving similarly vulnerable patients, residents, and staff.

“This study demonstrates the tremendous impact of adding Synexis DHP technology as a layer of protection in long-term care communities,” said Dennis Doyle, CEO, Synexis. “Staff shortages in healthcare, specifically long-term care, only further complicate infection prevention for patient populations, particularly those who may be vulnerable. Our continuous DHP technology provides continuous microbial reduction without creating additional burden for healthcare staff.”

Significance for Long-Term Care

Long-term care facilities have been particularly vulnerable to COVID-19 and other airborne respiratory illnesses. This study’s findings suggest that continuous operation of Synexis DHP devices can play a vital role in reducing environmental microbial burden, complementing existing infection and control protocols such as manual cleaning, masking, and vaccination efforts.

About Synexis

Since 2008, Synexis has been committed to continuously cleaning the air we breathe and the surfaces we touch. Synexis is an industry leader in touchless and continuous air and surface microbial reduction of occupied spaces. Our innovative Dry Hydrogen Peroxide (DHP®) fights viruses, bacteria, fungi (including molds), and VOCs. Our patented devices have undergone rigorous testing by Underwriters Laboratories (UL) and were certified to meet UL2998 for zero ozone emissions and can run 24/7 within occupied spaces.

 

Synexis devices provide DHP coverage to more than 40 million square feet of indoor spaces in a variety of industries such as Healthcare, Education, Sports & Recreation, Food Services, Food Safety, and many more. Synexis systems are regulated by the US Environmental Protection Agency and state governments. Synexis devices are produced in EPA-registered facilities and packaged and labeled in accordance with EPA regulations appearing at 40 CFR 152.500.
