The Cleanse Spa is a professional detoxification system which helps with total body purification. Ions are atoms or molecules that in most cases carry either a positive or negative charge. When the machine is turned on ions are created in the water. When the unit is set to positive, the current is directed to the positive pole, which produces more negative ions in the water. Therefore, a positive polarity generates a negative ion flow which, raises blood pH from acidic toward alkaline in scientific studies. When the detox unit is set to negative, the current is directed to the negative pole, and the opposite occurs, which results in more positive ions in the water. Therefore, negative polarity generates a positive ion flow which lowers blood pH from alkaline toward acidic.
