Replacement Water Filters

Reverse Osmosis systems offer a more advanced treatment process than carbon filtration only, or entry level pour-through pitchers. At the heart of the system is a reverse osmosis membrane which removes impurities as small as an atom! Additionally, your water passes through a series RO filters of sediment and carbon, eliminating any unwanted tastes and odors giving your water a polished fresh taste.

About your Reverse Osmosis Membrane:

TFC Membrane vs CTA Membrane
RO TFC membranes are recommended over the CTA reverse osmosis membranes due to their superior performance on water supplies with high pH, TDS & hardness. Additional benefits of TFC membranes include:

Greater Reduction of Contaminants	Longer Life
Better for Low Pressure Applications	More Water Production

Upgrading Reverse Osmosis Membranes to Higher Gallon Output:
If selecting a higher gallon membrane than your original system, you must also select a matching flow control. This is critical to insure adequate flushing and long term function of your system.

Reverse Osmosis Membrane Retrofitting CTA with TFC:
TFC Membranes require non-chlorinated water. To retrofit your CTA RO membrane with the TFC membrane on chlorinated water supplies, replace the Sediment Prefilter with the Carbon Block Prefilter RO filter to remove the chlorine. If your system has 2 prefilter housings, install this RO filter in the second housing after the sediment filter. On non-chlorinated water supplies, no change to the Prefilter is necessary.
