Synexis is the first company to create and patent Dry Hydrogen Peroxide (DHP), the true gas form of hydrogen peroxide.

Made from naturally occurring elements already in the air, DHP is designed to safely and effectively break down pathogens—flowing freely and continuously through indoor spaces to reduce the presence of microbes in the air and on surfaces, with no reliance on the exchange of air.  

The breakdown: DHP & microbes.

Our DHP molecule has a structure similar to a water molecule. Since all microbes (like viruses and bacteria) require water to live, they meet our DHP molecule in the air and on surfaces and attach themselves.

Once attached, DHP breaks down the microbe’s outer cell membrane leading to its destruction. So long microbe!

Is DHP safe?

Short answer: Yes. But we know the details matter. Let’s break down the finer points.

Synexis’ DHP technology does not emit ozone.

DHP is manufactured at an EPA registered establishment in accordance with the Agency’s requirement for devices. Synexis devices also underwent rigorous testing by Underwriters Laboratories (UL) and were certified to meet UL2998 for zero ozone emissions.

To achieve this certification, products must demonstrate that they emit less than the maximum ozone concentration limit of 0.005 ppm (5ppb), which is below the quantifiable level for ozone testing. Synexis proudly passed this test.

Outperformed OSHA safety standard1.

DHP is deployed at less than 20 parts per billion, which produces extremely effective microbial reduction at incredibly safe levels of H202. Basically, a single Synexis unit would have to run non-stop for 2.5 years to reach the same concentration of 1 droplet of a 3% aqueous solution of H202, which is the Hydrogen Peroxide you know as a brown bottle inside your medicine cabinet. At these levels, DHP concentrations fall far below acceptable safety limits for human exposure established by OSHA.

Attacks microbes while you work.

DHP was designed specifically to allow people to safely remain inside the same room where the technology is breaking down microbes. DHP will continuously attack microbes while everyone in the space goes about their day, no disruption needed. Hydrogen Peroxide already exists inside human lungs. And the DHP from Synexis flows at levels well below those naturally maintained inside the lungs.

Attacking microbes in the air and on surfaces.

Microbes like viruses, bacteria, mold, and chemical odors pose the biggest health risks and can be passed along in the air and on surfaces, potentially creating an endless and dangerous cycle. But DHP reduces microbes in even the hardest-to-reach areas.

Not every cleaning method can conquer microbes both in the air and on surfaces. Manual cleaning often misses microbes in the air, and still, the surfaces are only as clean as the last scrub. Methods like UV Light and Hydrogen Peroxide Vapor may address both but are toxic upon direct exposure to people. DHP doesn’t have these challenges.

Numbers tell the tale.

Synexis doesn’t discriminate. It attacks and breaks down every species and type of microbe on which it’s been tested. As a data-driven company, we use both 3rd-party and real-world testing, in the size of real-life environments, to optimize a pioneering microbial reduction approach that produces cleaner and productive environments for our clients.
