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!

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.
