If the water from your reverse osmosis (RO) system flows slowly or doesn’t taste as fresh as usual, it may be time to replace the filter cartridges in your water filtration system. We offer replacement filters and cartridges for reverse osmosis systems from trusted manufacturers, including Water Factory SQC and PRO models, GE SmartWater System, Pentek, and Watts Premier. Browse our selection of replacement pre- and post-filters, contaminant reduction filters, water filter kits, and other replacement parts needed to keep your RO system running at optimal performance.
About the Reverse Osmosis Membrane
Thin Film Composite Membrane vs. Cellulose Tri-Acetate Membrane
RO TFC membranes are much more effective than CTA reverse osmosis membranes due to their superior performance on water supplies with high pH, TDS, and hardness. Additional benefits of TFC membranes include:
Greater reduction of contaminants
- • Longer membrane life
- • Better for low pressure applications
- • More water production
If purchasing a higher capacity membrane for an RO system, you must also select a matching flow control. This will insure adequate flushing and the long term functioning of the reverse osmosis system.
Reverse Osmosis Membrane Retrofitting CTA with TFC
TFC membranes require non-chlorinated water. All municipal water supplies use chlorine or chloramine as a disinfectant. If retrofitting a system that originally used a CTA RO membrane, make sure to replace the sediment prefilter with a carbon block RO prefilter to remove the chlorine. If the RO system has two prefilter housings, install the carbon block RO prefilter in the second housing after the first sediment filter. On non-chlorinated water supplies, no change to the prefilter is necessary.
