From hotels and resorts to movie theatres and country clubs, and even casinos and cruise ships all welcome guests from around the world. And sometimes these guests bring more than just their luggage. But cleaning crews may have limited time for a thorough scrubbing, and other methods like UV Light are toxic to guests. Luckily, Synexis is the perfect accouterment for any room.

Our DHP™ (Dry Hydrogen Peroxide) producing biodefense system continuously attacks microbes in the air and on surfaces. We fight viruses, bacteria, insects, and odors without ever making guests leave the lounge or kicking players off the casino floor.

Our impressive DHP 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), otherwise known as DHP.

The creation of this technology makes us pioneers in the area of microbial reduction. That’s right, pioneers. Here’s why.
Continuous Clean
DHP works continuously, (the 24/7/365 kind of continuously) to reduce the levels of microbes in the classroom, dormitory, or any indoor space students go—both in the air and on surfaces.
Naturally Safe
DHP is a form of gas whose molecule, Hydrogen Peroxide, is a natural component of human lungs. DHP occurs at levels well below OSHA’s standard1, and Underwriter Laboratories (UL) has declared our DHP BioDefense system to be non-ozone producing.
Commands the Room
DHP flows wherever air flows, throughout any indoor space—reducing the presence of microbes without anyone having to leave the room, unlike other methods.
Low Maintenance
Just turn it on and go about your day. DHP works behind the scenes with very little upkeep, no operating staff, and no disruption to anyone’s routine.

In the air and on surfaces: Where DHP flows.

Hotels & Motels
Manual cleaning has its merits, but a maid service is only as effective as its last scrub. From the drawers of a guest’s dresser to the buttons in the elevator, microbes are everywhere—and Synexis can cut them down both in the air and on surfaces.
Playing cards. Slot machines. Cups full of quarters. Guests may be feeling lucky, but so do the microbes crawling all over them. Synexis works to continuously attack viruses and bacteria through every hour of the night.
Cruise Ships
Cruise ships are small communities that create perfect hotspots for microbes in the air and on surfaces. But the continuous ebb and flow of DHP from Synexis will help keep microbes at bay.
All-inclusive vacations shouldn’t include the stressful presence of microbes, like viruses, mold, and odors. Good thing the continuous flow of DHP makes reducing microbes a breeze.
The Birch Ridge Inn

Cleanliness beyond what guests can see.

As a proud innkeeper, Bill Vines knows that guests are constantly arriving with their own viruses, bacteria, and, yes, odors too. But a clean space is critical for repeat guests, so Vines turned to Synexis.
