HydroLogic® Stealth-RO™ 150 & 350 Membrane Element - 350 GPD - 98%+ TDS Reduction Replacement Membrane

HydroLogic® Stealth-RO™ 150 & 350 Membrane Element - 98%+ TDS Reduction for Stealth-RO™ Systems

Keep your HydroLogic® Stealth-RO™ 150 or 300 running at peak performance with the genuine Stealth-RO™ 150 & 350 Membrane Element. Rated at 350 GPD and delivering 98%+ total dissolved solids (TDS) reduction — superior to the 94%+ reduction of many larger RO membranes — this OEM replacement membrane ensures your Stealth-RO™ system continues to deliver ultrapure water for precision hydroponics and controlled cultivation applications.

Key Features & Benefits

• 98%+ TDS reduction: Industry-leading 98%+ TDS reduction provides the highest purity starting water for nutrient solution preparation and growing applications.
• 350 GPD rated capacity: Provides the membrane throughput capacity for both Stealth-RO™ 150 and Stealth-RO™ 300 system configurations.
• Temperature-responsive output: At 77°F, the membrane delivers 100% of rated output. Output adjusts proportionally as water temperature changes seasonally.
• OEM fitment: Genuine HydroLogic® membrane designed for exact fitment and performance in Stealth-RO™ systems.

Who Should Use This

Essential replacement component for commercial growers, hydroponic operators, and precision cultivation facilities running Stealth-RO™ 150 or Stealth-RO™ 300 systems who want to maintain maximum TDS reduction and system output volume.

Compatibility

Compatible with Stealth-RO™ 150 and Stealth-RO™ 300 systems. Replace when product water volume decreases and/or ppm readings increase from baseline. Allow water to run for one hour before collecting for use after installation.

Frequently Asked Questions

Which systems is this membrane compatible with?

This membrane element is compatible with HydroLogic® Stealth-RO™ 150 and Stealth-RO™ 300 systems.

When should I replace the membrane?

Replace when product water output volume decreases and/or ppm readings increase from your system's normal operating baseline.

What TDS reduction does this membrane achieve?

This membrane achieves 98%+ TDS reduction — higher performance than many RO membranes rated at the standard 94% level.

How does water temperature affect output?

At 77°F the membrane delivers 100% of its rated output. Output decreases as water temperature drops and increases as temperature rises. Monitor output and ppm readings seasonally when source water temperature changes.
