## Description

Operation Specification: FEED WATER PRESSURE :35 - 100 PSI TEMPERATE: 40 - 110°F/5-45°C PH :3.0 -11.0 MAX TDS 1000 MG/L TURBIDITY <1.0 NTU MAX SDI <4.0 HARDNESS <5 GPG IRON <0.1 Life time :15-24months as your feed water quality Shelf life: 3years in original sealed package. More valuable information: ✪What is dimension of the Geekpure 75GPD Ro membrane? It is standard size ( Membrane Dimensions: 11. 75" Overall Length, 1. 75" Diameter), and Fits all Standard 2" ID Membrane Housings. ✪What is the life time? Our suggestion is 24 months for most tap water (200-500ppm).usually, you replace membrane depends on usage amount and feed water quality. if tap water is very good quality (200ppm or less), you may replace the membrane per 36months. if hard water area, someone replace membrane 6months or 12months. it is time to replace if flow rate is too less or membrane is cloged. ✪Could i use it if my water Total Dissolved Solids is over 1000 ppm or well water? Yes, you can use it. even TDS reach 2000 ppm. but you should replace membrane every 12 months or more frequently.1000ppm is our suggestion. ✪Can this be used for brackish water(5000ppm) or ocean water with high salinity(35000ppm)? No. it is just designed for residential tap water use. if you need Ro membrane for brackish water or ocean water and industrial use, Geekpure can provide too, please send email to us. ✪ What is in the box? Just 2 x 100 GPD RO membrane in the box. membrane housing, wrench and flow restrictor need to be bought separated. Note: 1. DO NOT FREEZE. 2. If you have chlorinated water, we recommend you use a Carbon/Sediment Pre-Filter. The residual chlorine in municipal or city water will destroy the membrane. if hardness is too high, we recommend you install water softener before Ro unit.

Review: Fantastic RO Membranes. Used a few different makes over the years but these perform well and give a consistent high quality permeate water output. I live in a hard water area and these membranes work their socks off to give a permeate output of around 6ppm.
Review: I switched to these membranes a while back. I use them at work with DI after the RO system. Most importantly they always reject at least at 99%. I use the 100 gpd. With a permeate pump it will perform better and make water faster by about 80% when used on a drinking water system. I consistently see the tds at 1 or 2 ppm out of the membrane. Not the case with a lot of other membranes.These hold at 99% for a long time like a year or longer. Really depends on the incoming tap water temperature. tds, pressure and a water softener really helps RO systems run really pure. Then for drinking I use a mineral cartridge to add back in higher ph, Calcium and magnesium. So it will go from 1 or 2ppm to around 40ppm after the mineral cartridge. My customers tell me I turn them into water snobs..That’s how much they like the water including myself.
