OFF
Do yourself a favor and read about why taking a shower with chlorinated water is unhealthy. Hint, it has to do with more than your skin... (it's breathing in the vapor/steam). This filter works quite well since it effectively removes chlorine and doesn't seem to reduce the water flow by a noticeable amount. OK, the real answer is that I don't notice any reduction in flow rate at all but I have excellent pressure in my home. I have recommended this to several female friends of mine who have all said that their hair and skin seem softer after having installed the filter. Good luck and I hope this information helps you make a well-informed decision.
