How Ozone Air Purifiers Work

Ozone air purifiers, also known as ozone generators, are devices designed to cleanse the air by producing ozone gas (O3), which is a strong oxidant and has the ability to neutralize odors and eliminate airborne pathogens.

The working principle of these machines involves two primary methods to generate ozone: corona discharge and ultraviolet (UV) radiation. Below is a simplified breakdown of how these machines operate:

Corona Discharge Method:

  • Electric Arc: A high voltage arc mimics natural lightning, creating ozone.
  • Process: The electric arc passes through a gap filled with oxygen (O2), splitting the oxygen molecules into individual atoms.
  • Formation: These free oxygen atoms then attach to other oxygen molecules to form ozone (O3).

Ultraviolet Light Method:

  • UV Radiation: Utilizes UV light at a specific wavelength (typically 254 nanometers).
  • Splitting: The UV light breaks oxygen molecules into individual atoms.
  • Combination: Similar to corona discharge, the free atoms combine with oxygen molecules to produce ozone (O3).

When using an ozone generator, it is essential to understand the nature of ozone gas:

  • Strong Oxidant: Ozone has the power to react with contaminants.
  • Short-lived: Ozone naturally reverts back to oxygen after a while, often requiring the space to be ventilated post-usage.
  • Health Consideration: High concentrations of ozone can be harmful to health; hence, rooms should be evacuated during use.
