CS-1 Reverse Osmosis
Compatible Replacement Water Filters
Nimbus RO Membranes differ from Standard RO Membranes in that they have the Feed Water and Waste Water connections switched.
Standard RO Membranes have the end with a single port as the inlet feed water. On the end with two ports the center port is the permeate (product) water. The offset port is the brine (waste).
