Did you know that your body absorbs more chlorine during a shower than by drinking the same amount of water. Chlorine has been connected to a number of health problems. Chlorine can also dry out hair and skin. Our all-in-one showerheads and filters save water (2.5 gpm) and filter out iron oxides (rust) hydrogen sulfide (sulfur smell) and scale, in addition to 99% of the chlorine. Parts can be recycled and / or composted. Cartridges should be replaced approximately every 6 months.
