Chlorine, considered one of the most toxic chemicals found in nature, is universally used by the local municipal water supply to reduce and kill bacteria and viruses found in water systems. The chlorinated water from a hot shower or bath can irritate the skin and hair, cause cell deterioration, and offset ph balance. Toxic shower steam can also aggravate the respiratory system and the eyes. Our shower filters convert chlorine in shower and bath water into a harmless soluble chloride that washes out of the filter and is harmless to humans. In addition, they are easy-to-install - in the case of our bath balls it's as simple as placing it in the bath. By using bath and shower filters to reduce chlorine exposure, you will not only be healthier but your hair and skin will feel younger too!
