Make a good shower even better by attaching the Culligan ISH-100 Inline Shower Filter to your showerhead. It attaches easily to the existing standard half-inch shower arm at one end and then to the existing showerhead at the other, without affecting the height or positioning of the showerhead. This bathroom shower filter filters out chlorine from the water, providing you with softer skin and hair due to reduced exposure to chlorine. Its bacteriostatic filtering system reduces the growth of bacteria and fungus in water. The cartridge change reminder sticker lets you know when there is a need to replace the filter. This chlorine shower filter is easy to install and doesn't require any tools.
