Review on ISpring AFR450 Flow Restrictor Limit by George Saunier

Revainrating 5 out of 5

This is normal, although other manufacturers claim higher flow rates for 75GPD membranes

Not much to say about this. It works. However, after reading a bit, I found out that other manufacturers recommend 550 for a 75GPD reverse osmosis membrane. It seems normal if you have hard water like we do.

Pros
  • Inspires confidence
Cons
  • Out of fashion
