Product Description - Fits the Showerwise Shower Filter System KDF-55 and Chlorgon Filter contains 50% more filtering material for a longer, more effective lifetime, typically lasting 12-18 months. You’ll enjoy softer skin, healthier scalp and shinier hair after a Showerwise shower. Why? Because chlorine, commonly used to disinfect tap water, can make your skin dry, sensitive, flaky and itchy. It irritates your eyes and makes your hair dry and unmanageable. Worse yet, chlorine and chlorine by-products aggravate symptoms for many asthma, allergy, sinus and emphysema sufferers. The Showerwise difference… You may be shocked to know that your body can absorb more chlorine in a 1-minute shower than from drinking 8 glasses of the same water. But you can relax… chlorine is reduced by 95% with Showerwise. Also reduced is iron, lead, mercury and hydrogen sulfide. Bacterial, fungal and mildew growth are effectively inhibited. Showerwise’s patented KDF-55 and Chlorgon filter material performs best in warm or hot water, unlike ordinary carbon filters that are effective in cold only.
