Sale price$114.99

Replacement RO Membrane for Excalibur Superior Series RO Systems

The RO Membrane 75 GPD (RO TFC75) is a genuine Filmtec thin-film composite replacement membrane for Excalibur Superior Series RO systems. Rated at 75 gallons per day, it restores your system's full purification capacity — removing up to 99% of dissolved contaminants from your drinking water.

What the RO Membrane Does

The RO membrane is the most critical component of your reverse osmosis system. It's a semi-permeable thin-film composite membrane that forces water through microscopic pores, blocking dissolved contaminants including lead, arsenic, nitrates, fluoride, chlorine byproducts, and total dissolved solids (TDS). Over time, the membrane loses efficiency and must be replaced to maintain water quality and flow rate.

Who It's For

This membrane is for owners of Excalibur Superior Series RO systems using a 2" x 10" membrane housing. If you've noticed a rise in your filtered water's TDS readings, a drop in flow rate, or a change in taste, it's likely time for a membrane replacement.

Specifications

  • Model: RO TFC75
  • Type: Thin-Film Composite (TFC) Filmtec
  • Capacity: 75 GPD (gallons per day)
  • Size: 2" x 10"
  • Compatible System: Excalibur Superior Series RO

When to Replace

Replace your RO membrane every 2–3 years, or sooner if you notice a significant increase in TDS readings, reduced water flow, or a change in taste. Using a TDS meter to monitor your filtered water is the best way to know when replacement is due.

Why Filmtec?

Filmtec membranes (manufactured by DuPont) are the industry standard for residential RO systems — known for consistent performance, high rejection rates, and long service life. This is the same membrane technology used in the original Excalibur system.

Installation

The membrane installs into the 2" x 10" membrane housing of your Excalibur Superior Series RO system. Flush the new membrane for several minutes before use to clear any preservative solution. For guidance, visit our System Guide or contact us for support.
