Geekpure Reverse Osmosis RO Membrane 75 GPD - NSF Certified Water Filter Replacement Pack 2

Reverse Osmosis Filtration: Why Choose Hidrotek?

Hidrotek's high-efficiency reverse osmosis (RO) membranes reject impurities down to 0.0001 microns, providing superior water purity. With a high permeated flow and stable salt rejection, these NSF/ANSI Standard 58 certified filters can remove up to 98% of contaminants (minimum 96% rejection) from the source water, including heavy metals, fluoride, calcium, magnesium, lead, colloids, chromium, and nitrates.

The Hidrotek RO membranes come in a universal standard size (11.75" length, 1.75" diameter) that fits most residential RO and water filtration systems with 2" ID housings. This ensures a simple, hassle-free installation process.

Operation Specifications: - Feed Water Pressure: 35 - 100 PSI - Temperature: 40 - 110°F / 5 - 45°C - pH: 3.0 - 11.0 - Maximum TDS: 1000 mg/L - Turbidity: < 1.0 NTU - Maximum SDI: < 4.0 - Hardness: < 5 GPG - Iron: < 0.1

Lifetime and Shelf Life: - Operational Lifetime: 15 - 24 months, depending on feed water quality - Shelf Life: 2 years in original sealed package

Important Notes: 1. Do not freeze the membranes. 2. Flush new membranes for 30 minutes to remove any protective materials. 3. If the feed water is chlorinated, use a carbon/sediment pre-filter to protect the membrane. High hardness water may require a water softener before the RO unit.

Wastewater Ratio: 1:2 (1 gallon of pure water produced for every 2 gallons of wastewater)

Q&A: Q: What are the dimensions of the RO membrane? A: The membrane dimensions are 11.75" overall length and 1.75" diameter, fitting standard 2" ID membrane housings.

Q: What is the membrane's lifetime? A: For most tap water (200-500 ppm TDS), the recommended lifetime is 24 months. The actual replacement frequency depends on usage and feed water quality. In high-TDS or hard water areas, the membrane may need to be replaced every 6-12 months.

Q: Can this RO membrane handle water with TDS over 1000 ppm or very hard well water? A: Yes, the Hidrotek RO membrane can handle TDS up to 2000 ppm, but the membrane may need to be replaced more frequently (every 12 months or sooner) in such conditions.

Q: Can this RO membrane be used for brackish water (5000 ppm) or seawater (35,000 ppm)? A: No, this RO membrane is designed for residential tap water use only. For industrial or brackish/seawater applications, please contact Geekpure for specialized RO membrane options.
