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

Cellular disruption occurs. (/gold-standard-in-disinfection/).]
