The paper presents the evolution of the concentration level for four particle size groups of microaerosols (1.0, 2.5, 4.0 and 10.0 µm) in correlation with the microclimatic characteristics (temperature, humidity, lighting, pressure and concentration in CO2 and O2) in three active areas of the Targu Ocna Saltworks, currently used in treatments with solions (hydrated aerosols): in the vicinity of the walls of the old mining salt room, where there is a semi-wet static regime (SSR); in the transition area between the old rooms of exploitation with the semi-wet dynamic regime (DSR); and in the area of the waterfall and the marshy lake with the dynamic wet regime (DWR). The first and last halochamber are the ones recommended for cardio-respiratory, immuno-thyroid and osteo-muscular conditions, as well as in psycho-motor disorders. Based on questionnaires carried out over the course of a year, between 1 September 2021-31 August 2022, in two periods of stationing/treatment: a cold one (15 September 2021-15 December 2021) and a warm one (1 May 2022-30 July 2022), correlated with the data from the Salina medical office, achieved the profile of the improvement rate of the patients' ailments depending on the type of treatment (working regime in halochambers). These studies have allowed the optimization of the treatment conditions in the artificial surface halochambers in order to reduce the stationary period and optimize the treatment cycles.
