Does Your City Use Chlorine or Chloramine to Treat Its Water?

Quick Summary:

More than half of big US cities don't use chlorine, in part because free chlorine in water is highly reactive and has a short half-life and can interact with other substances to create harmful compounds thought to be carcinogenic.

But there's at least one exception in the United States: The Weddell Duo inline shower filter is certified to remove chlorine from water systems treated with free chlorine.

The certification arm of the National Science Foundation, which has seen drastic and systematic cutbacks in recent months under DOGE, traditionally offers reliable testing standards for chlorine removal for water filters, certifying chlorine removal over thousands of gallons of water.
