The salt we use for our respiratory treatments is pure sodium chloride (NaCl): all moisture and other trace elements found in raw salt are removed. Pure NaCl is placed inside a Halogenerator that crushes the compound into micro particles. The particles are pushed into the salt room or into the glass covered salt bed until a predetermined concentration level is reached. Your most important job in the process is to simply breathe properly. Slow, deep and rhythmic breathing enables the salt to circulate more efficiently through your respiratory system.
