The Synexis Biodefense System has been effective against every species of dry microbe on which it has been tested.

Dry Hydrogen Peroxide (DHP) is  generally effective against any organism that is susceptible to other forms of Hydrogen Peroxide.

List of Organisms Against which Dilute Hydrogen Peroxide (DHP) Technology is Reported to be Effective:


Feline Calicivirus (Norovirus substitute)
Influenza A (H1N1)
Escherichia coli bacteriophage MS2 (ATCC 15597-B1)

Additional Notes

In controlled, accredited lab testing DHP technology has demonstrated the ability to reduce 99.8% of H1N1 in one hour (sample size 1,120,000 viruses per square inch); 95.15% of MRSA in six hours (with soil load, sample size 100,000 bacteria per square inch, 99.53% without soil load); and 51% of C-Diff in 72 hours (sample size 3,780,000 bacteria per square inch, with soil load). 

In a specific maritime environment test, a client specifically asked for sampling to determine whether or not Salmonella and Listeria were present after testing, neither organism was detected.

DHP Technology has also been effective against a variety of fungi in multiple contaminated environments not identified by species.

Exclusion of an organism from this list does not imply inefficacy.  As we continue microbial testing, new results will be posted.  Please contact us with questions regarding specific microbes or testing.
