Founded in 2008, Synexis® LLC is a pioneer in the microbial reduction of occupied spaces. Using our patented technology, Synexis is the sole developer of the process by which naturally occurring oxygen and humidity are taken from the air to create Dry Hydrogen Peroxide (H2O2) or DHP™. Wherever air goes in an indoor facility, so too will DHP™ to help reduce the presence of viruses, bacteria, mold, odors, and insects.
The Synexis BioDefense System also underwent rigorous testing by Underwriters Laboratories (UL) and were certified to meet UL2998 for zero ozone emissions—working continuously without disruptions or changes in workflow. Synexis currently holds 16 US patents with 17 pending.[1] [2]

The Synexis® word mark is a registered trademark owned by Synexis LLC. Synexis® technology is classified as a pesticidal device and mitigates microbial load in the air and on surfaces. Synexis® does not claim to mitigate microbes on, or in humans, and does not claim to have an impact on patient outcomes. Synexis® is not intended to replace intermittent cleaning with EPA-approved disinfectants or as a substitute for the use of PPE as recommended in guidance set by local and state governments as part of their SARs-CoV-2 response.

Jim Lee, the Founder of Synexis, attended West Point where he studied Radiological, Chemical, and Biological Defense. After serving in the Army, Jim returned to West Point to the Chemistry Department, where he directed the academy’s largest academic course. During this time, Jim was charged with creating more robust means for biological detection, this proved to be inefficient and uneconomical. Jim then switched the approach by developing a prophylactic means for mitigating biological contaminants. This is how the Synexis technology known as Dry Hydrogen Peroxide was invented.

Synexis-made DHP™ is created from the ambient oxygen and humidity of an enclosed environment moving across a proprietary membrane within the device. The resulting DHP™ is then blown into the occupied space by a fan used to move air across the membrane. Since it’s a true gas, it flows unaided to every corner of the occupied space, reducing viruses, bacteria, mold, odors, and insects in the air, on surfaces, and the most hard-to-reach places. When Synexis technology is installed, it operates safely*, effectively, and continuously, requiring maintenance only once per quarter.

Yes. DHP™ is a form of gas whose molecule, Hydrogen Peroxide, is a natural component of human lungs. Plus, DHP™ occurs at levels well below OSHA’s standard.1 Synexis Devices also underwent rigorous testing by Underwriters Laboratories (UL) and were certified to meet UL2998 for zero ozone emissions.[3] [4]
