A recent study by the U.S. Geological Survey revealed that nearly half of tap water in the U.S. contains PFAs, or "forever chemicals," which are known to be harmful to health. These chemicals were detected in 45% of faucets tested across the country, including both private wells and public water sources. With the Barrage Filtered Showerhead, you can reduce your exposure to these contaminants. This showerhead is designed to filter out PFAs, chlorine, and other harmful substances, providing you with cleaner, safer water.
