Pharmaceutical grade, drug-free, salt is put into machines called Halo Generators. These machines heat, grind, and then disperse tiny salt particles into an enclosed room. These salt particles enter the respiratory system and start to break down mucous and pollutant build-up. Breathing in this air rids the lungs of bacteria and toxins allowing your airways to expand to help ease your breathing. More oxygen entering the blood stream allows for more cell regeneration and overall wellness.
