At Kohler, we design our products to give you the right mix of functionality and style to bring comfort to your daily routines. The KOHLER® Aquifer shower filter works with most showerheads to reduce chlorine and odor in your water, while controlling scale, and to keep your shower clean and smelling fresh. The Aquifer showerhead filter finds the delicate balance of keeping the good while reducing harsh chemicals in water to help leave your skin healthy.
