Back when we bought our Berkey water filter, we also got a chlorine shower filter. We weren't able to put it up right away, but with all my nesting and "to do" lists in preparation for the baby coming, it is finally up. Installation was easy enough. The only slight drawback is that we had a detachable hand held shower head and it didn't work with this filter. It was also a low flow shower head to conserve water, whereas this one is not. Otherwise the shower filter works great and we can tell a difference in the water. The chlorine smell is gone, and although it hasn't been up very long, I think it may be helping our skin not to be so dry.
I decided that we needed a chlorine shower filter after all of my research on water filtration. You can read the What's In My Water series part 1, part 2, and part 3 for more information. Chlorine is added to water in order to clean it, but is actually a toxic chemical. While I'm thankful for chlorine and its role in preventing diseases and providing clean water, I do think its worth removing the chlorine before drinking or showering with the water. You can receive 6 to 100 times more chlorine by breathing the air around a shower or bath than by drinking the water. Big Berkey Water Filters has an informative article here on their blog about chlorine.
The shower filter lasts about a year and removes or reduces chlorine, hydrogen sulfide, microorganisms, scale and water soluble heavy metals such as lead, mercury, and iron. It also kills bacteria and inhibits the growth of mold, algae, and fungi. In an enclosed area like a shower, the chlorine in water can vaporize and be inhaled. The shower filter works by converting chlorine into a water soluble chloride. The chloride behaves differently than chlorine in that it cannot evaporate or be absorbed by the skin. More is explained about the process here.
I highly recommend Big Berkey Water Filters - they have great customer service. The first shower filter that we received ended up leaking from the silver band once we put it up. After an email to Big Berkey Water Filters about the problem, I had a new shower filter shipped to me right away along with a postage paid label to return the old one.
