(1) About mobility

An air ion moves according to the electric field because of its electronic properties. The velocity is proportional to the electronic field strength. The velocity per 1 (V/m) is defined as the mobility.

SI unit of velocity: (m/s)
SI unit of mobility: (m/s) / (V/m) = m²/Vs

In most cases, mobility is determined by the ratio between the amount of electronic charge the ion possesses and the mass of the ion.

Ions which have high/low mobility values are large/small ions respectively.

(2) Importance of mobility

Effects on the human body are closely connected with mobility of air ions. Small ions are more efficiently absorbed by the human body than the same amount of large ions because they have larger mobility values and diffusion coefficients.
