One of my children has very dry skin, so I’ve been looking for a way to remove chlorine from his bath/shower water to see if that helps. I filter chlorine out of our drinking water so why not filter it out of bathing water, since your body absorbs chlorine through your skin as well as through your GI tract? Shower filters are pricey but there are several bath balls available. We recently purchased one from Rainshow’r that contains a KDF formula made of 70% copper and 30% zinc. As chlorinated water flows through the bath ball, which you need to pull through the tub water for 5-8 minutes, the filaments cause the chlorine ions to combine with a metal ion to form harmless chloride. So while KDF is not a “filter,” it does change chlorine from an element into a compound.
The Rainshow’r maker also claims that their bath ball can break the bond between chlorine and ammonia in chloramines, allowing the chlorine to be converted to chloride. Chloramines form in your tap water when chlorine combines with nitrogen-containing compounds, such as the ammonia that is added by water treatment facilities to disinfect. Chloramine smell is most often associated with the smell at indoor pools.
Pulling the softball sized bath ball through the tub for 5-8 minutes isn’t terribly convenient, but I do believe it’s helping as I can no longer smell chlorine during my children’s baths. I’ve only been using it for a week so I don’t know if it will help with my son’s dry skin. But if it does work for the price, it’s a great deal!
