Founded in 2008 by Jim Lee, a former U.S. Army officer and chemical engineer (West Point alum). His vision: employ advanced antimicrobial methods in indoor spaces based on Dry Hydrogen Peroxide (DHP™) development through his earlier startup, Lee Antimicrobial. Synexis LLC emerged as the sole developer and patent-holder of continuous DHP generation in occupied environments.
Dry Hydrogen Peroxide (DHP™) is generated from ambient humidity and oxygen, dispersed as a true gas that spreads throughout indoor spaces, reducing viruses, bacteria, mold, VOCs, and even insects. It’s fully certified for zero ozone emissions (UL‑2998, CARB) and EPA‑regulated.
Earlier lab validation in 2021 showed DHP reduces active SARS‑CoV‑2 viral load in larger rooms—significantly cutting surface contamination within two hours. Clinical deployments followed: a pediatric oncology hospital in Guatemala saw a 44% reduction in hospital-acquired infections (HAIs) and a 61% lower odds of contracting HAIs, especially C. difficile, when DHP was used in the PICU.
A May 2025 peer-reviewed AJIC study from a long-term care facility showed two units with Synexis DHP devices had 0% and 13.3% COVID-19 attack rates, versus 66.7% in a control unit—despite shared staffing and identical cleaning protocols.May 2023 findings demonstrated DHP reduced Candida auris (a multidrug-resistant fungus) surface contamination from 70% to just ~17% in patient rooms, a statistically significant drop.
In September 2024, Synexis partnered with Diversey (a Solenis company) to distribute its DHP devices broadly within the healthcare sector across North America—bolstering access and delivery scalability. The technology has been installed in numerous real-world settings: K‑12 school districts in Kansas, university campuses, sports venues, food service operations, the NJ PGA corporate HQ, and more. Many organizations chose Synexis to mitigate microbial risk while keeping spaces occupied.
Synexis products now cover over 50 million square feet of indoor space across diverse sectors including healthcare, education, hospitality, sports, and food services. Holds at least 16 U.S. patents plus 17 pending, and data is backed by 7+ peer-reviewed studies, showing repeated efficacy in reducing HAIs, COVID-19 transmission, Candida auris contamination, and VOC or mold presence.
