Bests & Worsts Reviews from Amazon

Although not stated on Amazon's site, the Woder website claims this filter will not affect flow rate. I had my doubts as to whether Woder had obtained a dispensation from the laws of physics, so I figured when I ordered there would be some reduction in flow. Prior to installing the unit, I placed a 12-cup mixing bowl in the sink and measured how long it took to fill it and consistently got 43 to 45 seconds. After installing the filter, the laws governing hydraulic flow indeed held and it took anywhere from 60 to 62 seconds to fill the mixing bowl. This to me is an acceptable and expected flow reduction for what I'm getting: safe water from my kitchen's cold water tap.
