# Air ionization, positive ions

Sharp air cleaners has a technology called PlasmaCluster. They say that it produces negative ions $\ce{O-}$ and positive ions $\ce{H+}$ (the difference with classical ionization is that ionization produces only $\ce{O-}$, PlasmaCluster also produces $\ce{H+}$)

The air contains oxygen molecules so oxygen can be ionized. But the question is how H+ is created ? I know that the air is $5.5 \times 10 ^{-5}\%$ Hydrogen gas. Is this small quantity of hydrogen in the air ionized, or is water in the air is split via electrolysis, creating the $\ce{H+}$ ions?

The plasmacluster supposedly works by ionizing water molecules in the air into $\ce{H+}$ and either $\ce{O^2-}$ or $\ce{HO-}$ ions. These ions then, supposedly, actively attach themselves to and break down pollutants, neutralizing their charges by pulling them apart. After they achieve this, the ions come back together to reform water.
