GrowoniX High Flow Cold Water Replacement Membrane GXM200HF

GrowoniX High Flow Cold Water RO Membrane for 200 GPD

The GrowoniX high flow cold water RO membrane is a custom-rolled element that produces 200 GPD at a 2:1 ratio. It holds a consistent 97% rejection and flows about 8 gallons of pure RO water per hour. The element runs on as little as 20 PSI of incoming pressure, with a maximum feed of 80 PSI. That low-pressure design is the reason it keeps moving water when standard membranes stall. GrowoniX brought the high flow membrane to the industry first.

Built to Keep Water Flowing When It Turns Cold

Cold water is the quiet killer of RO output. Between 77 and 50 degrees, production can drop by half, because cold water is denser and harder to push through the membrane. This element is tuned for exactly that. You trade a little rejection for a much higher flow rate and steadier output through winter. The 2:1 waste-to-pure ratio also cuts wastewater against standard systems. It fits GrowoniX EX100/200/400 and GX150/200/300/400 systems, plus most other brands of RO filters.

Key Features

• 200 GPD output: Single custom-rolled high flow element producing 200 gallons per day at a 2:1 ratio.
• 97% rejection: Consistent total-dissolved-solids rejection brings your ppm down.
• 8 GPH flow: Delivers roughly 8 gallons of pure RO water per hour.
• Low-pressure operation: Runs on as little as 20 PSI incoming, with an 80 PSI maximum feed.
• Cold-water tuned: Holds flow through winter when cold, dense water normally slows production.
• 2:1 waste ratio: Cuts wastewater compared with standard RO systems.
• Wide compatibility: Fits GrowoniX EX100/200/400 and GX150/200/300/400, plus most other brands of RO filters.
