About this product

Replacement membrane for 50 Gallon per Day Revtex 1:1 Reverse Osmosis Membrane for GreenMachine RO Water Purifiers

The heart of the Vertex Green Machine is the reverse osmosis membrane. RO filtration technology removes on average 95% of the dissolved solids in your water. Dissolved solids are not removed by municipal water treatment. This is why RO purification is an important safety factor for the water you drink and the water you use in your cooking.

The Vertex GreenMachine uses the new Revtex 1:1 high-efficiency 50 GPD RO membrane to send less water to the drain. Only 1 gallon of water is wasted for each gallon of fresh water produced, significantly reducing the waste-water by up to 75% compared with standard RO membranes. This state-of-the-art membrane is manufactured using special membrane material along with an improved design to make a 50% recovery rate possible at a typical municipal water pressure of 40-100 psi.

**Replace membrane after 2-3 years.

Installation tips

  • Shut Off Water Supply: Turn off the feed water to the RO system.
  • Relieve System Pressure: Open the RO faucet to release pressure.
  • Access Membrane Housing: Locate and open the RO membrane housing.
  • Remove Old Membrane: Carefully pull out the used membrane using pliers if needed.
  • Install New Membrane: Insert the MAD-4230 membrane fully into the housing, ensuring proper seating and orientation.
  • Reassemble Housing: Reinstall and hand-tighten the membrane housing cap.
  • Restore Water Supply: Turn water back on and check for leaks.
  • Flush the System: Flush the system according to manufacturer instructions before drinking water is used.

Frequently asked questions

Will this fit my system?
Yes, if you have a GreenMachine PT‑4GR (4‑Stage) or PT‑5GR (5‑Stage). It is the specified Revtex 1:1, 50 GPD membrane for these models.

How often should I replace it?
About every 2 years, depending on water quality and use.

Why Revtex vs. a standard 50 GPD membrane?
Revtex is engineered for 1:1 water use, sending far less to drain while maintaining output, ideal for cutting water waste.

Do I need new pre-filters too?
Yes, good prefilters protect the membrane. Pair this with the PT‑5G or PT‑4G annual filter kit.

Is there a special wrench for 50 GPD Revtex 1:1 RO Membrane?
There is no special wrench for the membrane housings. It just unscrews. The housing-removal wrench from the kit does not fit the smaller RO membrane housing cap used with the Revtex 50 GPD element (MAD-4230). Please open the membrane housing cap by hand.

How much water can this membrane produce?
It is rated to produce up to 50 gallons of purified water per day under standard operating conditions.
