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® Cinq showerhead replacement filter uses Aquifer® filter technology and works with Cinq filtered showerheads. The Aquifer five-stage filtration system works hard to effectively reduce harsh chemicals that can strip your skin and hair. This replacement filter reduces odor and scale buildup in your shower, too.
