PC-ions can be generated by the discharge of plasma in a Plasma Cluster™ device. Plasma discharge can produce OH radicals from atmospheric hydrogen oxide to generate H3O+(H2O)n positive-cluster and O2−(H2O)n negative-cluster ions. It has been considered that charged PC-ions attach to the protein surface, hydroxyl radicals appear on it as a results of chemical interactions between the ions, and degrade it nonspecifically [17]. Neither NOx nor SOx are detectable during the production of PC-ions by plasma discharge (data not shown). There are several reports to show the degradation of protein and inactivation of virus by oxidation by ozone, it can be cogenerated with PC-ions by plasma discharge and other air-cleaning devices [18–20]. However, the amount of ozone cogenerated with PC-ions from our devices was negligible (less than 0.01 parts per million) and considered not to affect the protein degradation, significantly [17]. Therefore, we considered the degradation and impairment of IgE-binding capacity of the allergens were mediated by the generation of hydroxyl radicals produced by generation of PC-ions neither by generation of ozone.

This study was financially supported in part by the SHARP Corporation.

We tested device effectiveness using the same experiments from the Plasmacluster ioniser SHARP Co., Japan, the Nanoe generator Panasonic Co., Japan, and the Vion KING JIM Co., Japan, to test their advertising claims.
...
There was no significant difference in the number of colonies on plates exposed to devices compared to control, in the number for all devices, or in all bacteria tested in experiments in the 14.4 m3 chamber.
...
These results strongly suggest that the bactericidal effect seen only on the agar plate in narrow space was explained by ozone released in space as a by-product, not by special materials as advertising claimed. It is thus important to analyze the effect of special materials such as those done in this study and to suggest the involvement of ozone as the true cause, as have been done in this study, in evaluating bactericidal effect or viral inactivation as advertised by these companies.

The effect of ions on bacterial killing was compared with that of the ozone produced using an ion trap to remove the ions. The ionizer had the ability to kill the bacteria, and ion capture dramatically reduced its bactericidal effect, indicating that the ozone generated had little or no bactericidal effect under these conditions, and the ions produced were responsible for almost all the bacterial killing.
...
These results indicate that negative and positive ions generated by the ionizer are responsible for inducing oxidative stress and so reducing bacterial survival.
...
The ionizers (Plasmaster 2.5G) were supplied by LG Electric Company (Seoul, Korea).
...
The plasmaster 2.5G that we used generated about 35 ppb of ozone over 2 h in 100 L; however, in previous reports using ionizers ozone concentrations were reported to be from 100 ppb (8) to 2.3 ppm (3).

Aby ozón neprodukoval, tak musí mít pro pohyb vzduchu ventilátor.No a sebetišší ventilátor bude vždycky slyšet.

Léta jsem používal čističku vzduchu od Bioneru, s extra tichejma ventilátorama, pracíma filtrama, HEPA filtrama a ionizátorem.Vždycky po zapnutí byl ozón chvíli cejtit.Na nejtišší chod se s běžící čističkou dalo v místnosti v pohodě spát (monotónní tichej zvuk), ale při poslechu hudby to působilo, jako bych poslouchal kazeťák.Ten šum ventilátoru tam prostě slyšet je.Takže jsem to vypínal.

A v uzavřený místnosti se to používá pro to, že když je někdo silně alergickej na určitej druh pylu (trvá to třeba dva až tři tejdny), tak prostý vyvětrání mu moc neprospěje.A v noci se chce vyspat bez hepčíkání...
