Viruses and bacteria cower in the face of DHP™(Dry Hydrogen Peroxide).

No matter which industry you’re in, viruses and bacteria can exist undetected in the air and on surfaces for hours. Synexis DHP, our patented technology, was designed to safely, continuously, and effectively flow throughout indoor, occupied spaces to fight pathogens in the air and on surfaces.1


Coronavirus (MS2 Surrogate): >95% in-air reduction after 60 minutes2
Influenza Type A: 99.8% reduction after the first 60 minutes
Norovirus (feline calicivirus surrogate): 99.5% reduction after 2 hours


Clostridium Difficile: 51% reduction after the first 72 hours
Escherichia Coli (E. Coli): 99.99% reduction after the first 4 hours
Enterococcus Faecalis: 98.37% reduction after the first 6 hours
Listeria Monocytogenes: 97.36% reduction after the first 3 hours
Methicillin-resistant Staphylococcus Aureus (MRSA): 99.15% reduction after the first 6 hours
Pseudomonas Aeruginosa: 82% reduction after the first 3 hours
Salmonella Enterica: 99.13% reduction after the first 6 hours


Molds, fungi, and yeast are just simply allergic to Synexis.

Locker rooms, dorm rooms, weight rooms, hotel rooms, classrooms, whichever the kind, you’ll want Synexis to have your back. We use our patented DHP to weaponize naturally occurring oxygen and humidity to help reduce the presence of mold, fungi, and yeast.


Vegetative Aspergillus Niger (A. Niger): 86% reduction after the first 6 hours
Candida Auris: 6.58 log reduction after the first 48 hours


It really stinks for these odors and insects that Synexis is so effective.

From the nose-hair-burning chemical odors of industrial cleaners used in hospitals and schools to the plethora of pesky insects that inhabit poultry plants and restaurants, Synexis DHP flows through indoor spaces attacking these microbes in the air, on surfaces, and in hard-to-reach areas without interrupting your employees’ workflow.

Published Studies

Clinical Study Published in American Journal of Infection Control: Evaluation of DHP in Reducing Microbial Bioburden in a Healthcare Facility⁴

Sunrise Hospital, a 762-bed acute care facility in Las Vegas, NV, conducted a study evaluating the efficacy of DHP Technology on microbial air and surface contamination as an adjunct to routine cleaning and disinfection. Published in AJIC, the powerful results tell the tale all themselves.

DHP demonstrated a statistically significant 96.5% reduction in the average number of bacteria collected in all surface environmental samples after one day (p < .001). The greatest reduction was seen on soft surfaces (like notoriously hard-to-clean privacy curtains) where DHP demonstrated a 99.5% reduction after one day. Explore more results from this extensive study below.

Effectiveness of DHP on Reducing Environmental Microbial Bioburden Risk in a Pediatric Oncology Intensive Care Unit

By analyzing surface samples from rooms in the intensive care unit before and after DHP was deployed, this study demonstrates that the overall mean surface microbial burden was significantly reduced.

Simply put, DHP was proven effective and improved the quality of environmental cleaning. Read more about the results.

DHP Technology for Reduction of Microbial Colonization in the Hospital Setting

In this study, DHP was incorporated into a community hospital’s 34-bed Cardiovascular/Telemetry unit’s existing HVAC system. The study was designed to answer the question: Does DHP reduce microbial contamination in the hospital unit?

The results showed a significant reduction in microbes over seven days. Dig into the details below.

Clinical Study Published in American Journal of Infection Control: An Effective and Automated Approach for Reducing Infection Risk From Contaminated Privacy Curtains⁵

Privacy curtains are widely used in hospitals and healthcare spaces. Frequently touched by both providers and patients, they easily become contaminated—and are only as clean as the last time they were manually cleaned. Plus, they’re generally only changed out twice a year 

A study in AJIC describes the successful reduction of curtain contamination in five different units using continuous DHP technology. Results showed that the microbial load was reduced by 99.47% on Day 1. Read more about how the statistically significant reductions were maintained throughout the 28-day study.

Infection Specialists and Pharmacists Share Responsibility for Ensuring Patient Safety⁶

The United States Pharmacopeia (USP) has identified collaboration between infection preventionists and pharmacists as a necessary component of successful compliance with USP General Chapter <797>, the foundation of which is to prevent patient harm from microbial contamination.

Dramatic advancements in environmental technologies have helped mitigate the inadequacy of manual cleaning and disinfection. A case report from an inpatient hospital in Indiana determined that DHP technology continuously helps address active shedding and contamination in real time without disrupting pharmacy workflow, enabling successful compliance with USP <797>. Read about how they overcame their challenges with DHP technology below.

White Papers

Bipolar Ionization: Understanding the Difference Between Theory and Practice

Indoor air quality has increasingly become a priority for everyone from homeowners to facility operators. Ionization technology represents one of the major categories for air cleaners, but concerns over its safety and efficacy have led to cautionary warnings.

However, a basic understanding of the fundamental process is often critical to understanding whether the theory behind indoor air quality improvement and ionization will lead to the desired result. Dive into this breakdown of air ionization technologies to explore the differences between theory and reality.

Ultraviolet Germicidal Irradiation for HVAC Systems

Ultraviolet germicidal irradiation (UVGI) has been used in HVAC systems in an attempt to reduce airborne microbial contamination. This white paper examines the efficacy of UVGI and the number of factors that efficacy may be dependent on.

By comparing how DHP may also respond to those dependincies, the results show that because DHP is a near ideal gas, it is not impeded by shadowing, shielding, reflectivity, or other similar parameters.

A Taxonomy of Air-Cleaning Technologies Featuring Synexis

Solutions for occupied spaces are limited based on potential toxicity or harm to humans, such as UV power. Synexis and Dry Hydrogen Peroxide is the ideal solution as it continuously attacks microbes, flowing through any indoor space without anyone ever needing to leave the room.

In an independent laboratory test, Synexis DHP showed significant reduction of MS2 (surrogate for the SARS-CoV-2) at various time periods, both in the air and on surfaces.
