This is the universal fit filter that instantly purifies shower water by removing chlorine, harmful chemicals, and impurities, leaving you feeling clean and refreshed after every shower. The filter contains a patented bacteriostatic media and crystal quartz that, unlike activated carbon, is effective in hot water and reduces chlorine, sediment, fungus, algae, and odors in shower water. Unlike lesser shower filters, it purifies for up to a year before needing replacement. Installs without any tools on almost any shower head. Durable rust-proof polypropylene with a chrome finish. Includes an aroma therapy diffuser ring for creating a spa-like experience while you shower.
