Reverses Osmosis Membranes

Upgrade or replace your reverse osmosis membrane to restore optimal filtration performance. These Vertex-compatible RO membranes efficiently remove dissolved solids, chlorine, and contaminants to deliver clean, great-tasting water.

Available Options:

• 50 GPD Reverse Osmosis (MA-4203) – Standard output membrane used in Vertex PWC-1000R, PWC-1500R, PWC-1800R, and similar 2-temperature coolers.
• 75 GPD Reverse Osmosis (MO-4239) – High-capacity encapsulated membrane used in larger models such as PWC-3500R.
• 100 GPD Reverse Osmosis (MA-4205) – Standard-output membrane used in Vertex PWC-7000.

Key Features:

• Produces 50, 75 or 100 gallons per day of purified water
• Reduces dissolved solids (TDS), chlorine, and taste/odor impurities
• High-rejection TFC membrane for long-term performance
• Easy replacement – fits Vertex and compatible RO systems
• Typical replacement interval: every 2–3 years (depending on water quality and usage)

Dimensions: Standard 2" × 12" housing size (encapsulated type for 75 GPD only; 50 and 100 GPD are standard bare elements, ~1.8" × 11.75")
