LoginA novel indoor air purification technology using ions generated by discharge plasma hasbeen developed. With the application of AC voltage between electrodes, dischargeplasma has been occurred and positively charged ions and negatively charged ions havebeen generated at atmospheric pressure. The chemical compositions of the ions have beenclarified to H + (H2O)m and O2 (H2O)n by time-of-flight mass spectroscopy.Bacteriostatic and fungistatic effects of these ions have been investigated. All fourbacterial test strains used in this study have been inhibited in their re-growth capacity.The fungi have been inhibited in their germinating capacity with the use of thistechnology.
