What are the main differences between a Microsalt Salounge and traditional salt rock caves?

The main difference between so-called rock caves and Microsalt dry salt aerosol solutions is the quality of the salt microclimate. Normal salt rock caves that are built above ground by mounting salt rock walls never contain air with a salt aerosol dosage that is sufficient to create durable benefits.
Another big difference is that Microsalt Salounges are actively dried with fresh air that is brought inside the room throughout the whole session. This guarantees not only high quality of air inside the room but also that the relative humidity is never higher than 40%. This creates big advantages for both air quality, aerosol quality as well as the lack of aggression of salt on its environment.
