Nowadays research in this field  are continued, and mainly it is directed to  development of equipment for normalization of ionic composition of air and equipment for control of ionic composition of air. At  the same time researches in the field of development of  mathematical apparatus for modeling time and spatial changes of concentrations of air ions are not numerous. In the article authors proposed to use continuity equation for description of dynamics of spreading of air ions indoors. It’s transformed to linear differential equation of order 1 with usage of  simplification and transformation, and for it’s solution was used Bernoulli equation. Solution of equation shows that concentration of air ions increases with approaching  to source, that was  confirmed by experiment. Also in article is proposed to use diffusion coefficient for characterizing of spreading of air ions, it allows to get linear nonhomogenous equation of order 2. In general  results of solution of such equation correlate with experimental data satisfactorily ER -
