The Oxynator Shower Head Filter - Gaiam. It's ESSENTIAL to get a shower WITHOUT all the chlorine from the typical city water systems. This is designed to ionically remove 99% of chlorine AND vapors that accelerate ageing and damage skin, hair, lung tissue. PLUS it draws in oxygen and infuses it into the filtered water, rejuvenating skin cells, making hair silkier, and enriching the lungs with oxygenated, purified steam. Says it also pays for itself ($108) in water conservation.
