Remove chlorine, chloramines, VOC’s, THM’s, pesticides, sulfur, heavy metals, hydrogen sulfide (“rotten egg” odor), iron oxides (“rust water”), dirt, sediment and other odors while balancing pH & de-chlorinating! It works by filtering the water through stages of our ERA® 6500 and ERA® 9500 medias. The results? The healthiest, most refreshing bath experience in addition to smoother, softer skin and hair that is less dry. Your tub and shower area will be cleaner too! The unique drop-down filter design allows for a substantial amount of filtration media enabling more contact time with the water. More contact time means better filtration.
