An apparatus for purifying air comprising two electrodes having a dielectric material such as glass extending therebetween. The dielectric material is air permeable, for example in the form of a bed of discrete particles such as glass beads. The electrodes are also air permeable, allowing the air to flow through the electrodes and dielectri c. Ozone is generated by discharge at points of contact of the dielectric particles. Airflow through the devise is improved, allowing greater cooling, and higher volumes of airflow but at lower concentrations of ozone production than with prior art devices, thus reducin g toxicity.
