SteraMist: how it works
How the SteraMist ionised hydrogen peroxide process disinfects and decontaminates a treated area, step by step.
Published 7 February 2024
In contrast to chlorine bleach, ammonia, benzene and volatile hydrogen peroxide disinfectants, the SteraMist ionised hydrogen peroxide (iHP) process uses the ionisation of a low concentration (7.8%) hydrogen peroxide (H2O2) solution to generate hydroxyl radicals (•OH), one of the most powerful oxidising agents in nature.
The hydroxyl radical is often described as reacting with pollutants, decomposing them, and affecting pathogenic viruses, bacteria, allergenic pollens and mould spores.
Step 1: Cold Plasma Arc
A low concentration (7.8%) hydrogen peroxide BIT solution passes through a cold plasma arc to convert it into ionised hydrogen peroxide (iHP).
Step 2: Dispersion
The ionised hydrogen peroxide is carried throughout the mist, moving like a gas through the treated area and reaching every surface.
Step 3: Contact
The ionised hydrogen peroxide affects micro-organisms through the oxidation of proteins, carbohydrates and lipids.
Step 4: Disruption
