Reverse Osmosis Membranes
The membrane is the heart of an RO system — the semipermeable element that actually rejects dissolved solids. We carry thin-film composite (TFC) residential and encapsulated membranes from Filmtec, Watts, PureT, Hydrotech and Omnipure, in the GPD ratings and form factors that fit standard and proprietary systems.
How to choose a membrane
Match GPD and size. Residential membranes are commonly 1812 form factor rated 50–100 GPD — match your system's rating.
TFC vs. encapsulated. Standard TFC elements drop into a membrane housing; encapsulated (PuROTwist-style) membranes include their own shell for tool-free swaps.
Proprietary fits. Rainsoft, Sears/Kenmore and other brands use specific membranes — buy the compatible listed for your unit.
Protect it. Chlorine destroys TFC membranes — always run carbon pre-filtration and change it on time.
Tell us your system or membrane part number and we'll match it. Start here.
