GrowoniX GXM-150-HR High Rejection RO Membrane
The GrowoniX GXM-150-HR is a custom-rolled, cold-water RO membrane in a 2" x 12" element. This High Rejection version delivers 97% rejection at a 2:1 ratio and flows about 6 gallons per hour of pure water. It is rated for 150 GPD and built from polyamide thin-film composite. It runs cold, from 50°F to 113°F. Rejection is the priority here, not raw flow.
Chlorine-Free Feed and Compatible EX/GX Systems
It fits the EX200, EX400, EX400-T, GX150, GX200, GX300, and GX400 systems. Chlorine capacity is 0 ppm, so always run dechlorinated feed water through a carbon stage first. Chlorine destroys thin-film membranes fast. Choose HR when you want the lowest TDS output and can accept a slower fill. Swap it once rejection drops off its baseline.
Key Features
- High Rejection Element: 97% rejection at a 2:1 ratio for ultra-low TDS output.
- 150 GPD / 6 GPH: Pure-water output sized for compact RO systems.
- 2" x 12" Thin-Film Composite: Polyamide element, custom rolled.
- 0 ppm Chlorine Tolerance: Requires dechlorinated feed, so run a carbon stage ahead of it.
- 50-113°F Operating Range: Cold-water-capable design.
- Wide System Fit: EX200, EX400, EX400-T, and GX150-GX400.
