the Second Shower Head Filter

Replacement filter cartridge for THE SECOND SHOWERHEAD — NSF/ANSI 177 certified Vitamin C shower filter that removes 99.9% of chlorine and chloramine with consistent performance through the entire 60-day filter life. Each cartridge infuses Vitamins E, B3 (Niacinamide), B5 (Panthenol), and B7 (Biotin) into your shower water for skin moisture, barrier support, and hair strengthening benefits. Sediment micron filtration captures rust, heavy metals, and particulate matter — pull out a used filter and the brown discoloration is visible proof of what was in your water. The Truth Window shows filtration progress in real time so you never have to guess when to replace. Swap in under 30 seconds with no tools required. Hard water areas may need replacement every 30-45 days. Compatible with all Second Shower Head colors. Subscribe for automatic delivery and never run out.
