“Passive” Salt Room

A passive salt room uses large amounts of salt in the room but does not have a Halogenerator. Passive salt rooms attempt to simulate the environment of a true salt cave, and control the climate by regulating the airflow, humidity and temperature to allow for an allergen and pollutant free environment.



An atom or molecule with a net electric charge due to the loss or gain of one or more electrons. These molecules surround us. Negative ions are commonly produced in natural areas, such as ocean waves, waterfalls, and rainstorms. Positive ions are commonly formed by high winds, dust, humidity and pollution; also by electronic devices such as air conditioning systems, florescent lights, cell phones and computer equipment.



Term typically used to refer to a class of drugs that are designed to thin and aid in the clearance of mucus from the upper and lower airways, including the lungs, bronchi, and trachea. Dry Salt particles are labeled as having these properties.
