Built with thin-film composite (TFC) membrane technology, this 50 gallon-per-day membrane delivers excellent contaminant rejection for cleaner, healthier drinking water. It’s a reliable drop-in solution for systems that require a 50 GPD membrane — restoring your system’s efficiency and purification performance.
Key Features
- Thin-Film Composite (TFC) Membrane – Advanced membrane technology for effective reduction of dissolved solids, heavy metals, and a wide range of contaminants.
- Rated 50 GPD Output – Produces up to 50 gallons of purified water per day under typical residential conditions (actual output varies with feed pressure and temperature).
- High Rejection Performance – TFC membranes deliver strong salt and impurity reduction for better tasting, lower-TDS drinking water.
- Standard Drop-In Design – Designed as a direct replacement membrane element for compatible housings — no special tools required for installation.

Applications
- Under-sink drinking water purification
- Whole-house point-of-use RO systems
- Replacement membrane in older Culligan RO units
- Restoration of production capacity for low-yield RO systems
Maintenance & Replacement
- Replace every 24 months (typical residential use), depending on water quality and feed conditions.
- Always pre-filter your water with sediment and carbon filters upstream to protect the RO membrane and prolong its life.
- Flush the membrane after installation to remove manufacturing preservatives and stabilize performance.
Why It Matters
The RO membrane is the heart of your reverse osmosis system — it performs the core purification work by separating dissolved contaminants from water. Over time, membranes can foul or lose efficiency, resulting in reduced water quality and slower production. Installing a quality replacement like the Culligan TFM-50-A 50 GPD membrane restores system performance and helps ensure you’re getting consistently clean, great-tasting water.
