Ionized Hydrogen Peroxide (iHP™)
Superior Life Sciences Disinfection & Decontamination
Maintaining an environment that is comfortable and free of contagions is essential to produce the most accurate research findings for our world in the life sciences realm, especially for those scientists working in biosafety laboratories who routinely handle the most lethal microorganisms known to science. Utilizing a decontaminant that is effective against pathogens and won’t harm sensitive laboratory equipment is essential to maintaining a productive work environment for these environments.
SteraMist, powered by Binary Ionization Technology (BIT), offers your life sciences facility superior material compatibility and boasts significant efficacy compared to other decontamination options, capable of eliminating all contamination challenges within critical environments faster than any competitors on the market and without the production of byproducts.
iHP™ Technology Explained
Step 1
7.8% Hydrogen Peroxide Bit™ Solution converts to iHP™ after passing through a cold plasma arc.

Step 2
iHP™ is carried thought the mist, moving like a gas throughout the treated area.

Step 3
iHP™ damages pathogenic organisms through oxidation of proteins, carbohydrates and lipids.

Step 4
iHP™ cellular disruption and/or dysfunctions occur and allows for disinfection and decontamination in the targeted area.
A. Electrodes
B. Nozzle
C. Atmospheric Cold Plasma Arc
D. ionized Hydrogen Peroxide (iHP™)
The atmospheric cold plasma arc converts the H2O2 molecules into iHP™. As one of the most powerful oxidizing agents in nature, the iHP™ kills the pathogens achieving high efficacy and leaves behind only oxygen and humidity in treated spaces.
iHP™ Technology Efficacy
Independent testing had proven six-log (99.9999%) efficacy against the gold standard for sterilization, Geobacillus stearothermophilus and Bacillus atrophaeus – a notoriously difficult to kill spore.
With this development, further EPA testing had placed it on the following Lists:
LIST G: Norovirus
LIST H: MRSA
LIST K: C. difficile spores
LIST L: Ebola
LIST M: H1N1
LIST N: Emerging Pathogens, Including SARS-CoV-2 Coronavirus
iHP™ Features Efficacy Against:
- Pseudomonas
- H1N1 (Influenza A Virus)
- Salmonella
- C. diff (Clostridium difficile) Spores
- Geobacillus Stearothermophilus Spores
- Staphylococcus
- Norovirus
- Mold & Mildew

iHP™ Technology History
Ionized Hydrogen Peroxide (iHP™) was developed as a direct response to weaponized anthrax attacks As an invention funded by a grant provided by the U.S. Defense Advanced Research Projects Agency (DARPA).
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the US military.
Complete Room Fogging Decontamination System
lonized Hydrogen Peroxide can achieve 6-log organism reduction on:
Bactericide
Virucide
- Application time: taking only 5 seconds per square foot to apply.
- Contact time to disinfect: 7-minute.
- Does not damage equipment so rooms do not need to be emptied. Even highly technical equipment can be left out.

iHP Competitive Advantage Analysis
VHP vs iHP
STERAMIST® iHP™ | vs | CHLORINE DIOXIDE |
---|---|---|
APPLICATION | ||
ionized Hydrogen Peroxide (iHP™) can be applied to every surface, including sensitive electronics. | May cause progressive damage to room surfaces and equipment not protected from fumigation. | |
UV INTERACTION | ||
SteraMist® iHP™ is unaffected by the presence of UV lights. | Requires shutoff of lights, as chlorine dioxide breaks down in the presence of UV rays. | |
OPERATION | ||
Does not require room preconditioning, and point-and-spray application requires no rinsing or wiping. | Five Stage Operation: Preconditioning, Conditioning, Charging, Controlled Air, and Aeration. | |
ODOR | ||
SteraMist® iHP™ leaves no odor. | Smell of chlorine remains after treatment. | |
STARTUP & PLACEMENT | ||
