About this item
- High Efficient-100 GPD RO membrane,Rejects impurities down to 0.0001 micron,Removes Heavy Metal,Arsenic,Lead,Mercury,Fluoride and more 1000+ contaminants from source water
- Pack of 4 x 100 gpd Reverse Osmosis Membranes in the box
- High Quality - NSF/ANSI Standard 58 certificated.Polyamide film composite material,food grade and BPA free
- Universal Compatible-Standard size ( Membrane Dimensions: 11. 75" x 1. 75" ), Fits 1812/2012 residential RO membrane housings (2” Inner Diameter )
- Life Span-It depends on usage amount and feed water quality. Usually,24 months or 35,000 Gallons pure water for most tap water (200-500 ppm)
- Friendly Design, Easy installation. It is suitable for most Reverse Osmosis Water Filtration System.Please note to flush new membrane 30 minutes.DO NOT FREEZE
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
Life time :15-24 months as your feed water quality
Shelf life: 2 years in original sealed package.
1. DO NOT FREEZE.
2. Please keep flush new membrane 30 minutes. Because there is protection material in it. then, TDS of pure water will be down to right level.
3. 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.

Question: What is dimension of the Ro membrane?
Answer: It is standard size ( Membrane Dimensions: 11. 75" Overall Length, 1. 75" Diameter), and Fits all Standard 2" ID Membrane Housings.
Question:What is the life time?
Answer:Our suggestion is 24 months for most tap water (200-500 ppm).usually, you replace membrane depends on usage amount and feed water quality. if tap water is very good quality (200 ppm or less), you may replace the membrane per 36 months. if hard water area, someone replace membrane 6 months or 12 months. it is time to replace new one if flow rate is too less or membrane is cloged.
Question:Could i use it if my water Total Dissolved Solids is over 1000 ppm or very hard well water?
Answer: Yes, you can use it. even TDS reach 2000 ppm. but you should replace membrane every 12 months or more frequently .less 1000 ppm is our suggestion.
Question:Can this be used for brackish water(5000 ppm) or ocean water with high salinity(35000 ppm)?
Answer: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.
Question:What is in the box?
Answer: Just 4 x 100 GPD RO membranes. if you need membrane housing, wrench and flow restrictor ,please buy it separated.
Different temperature,different water pressure and feed water quality, the product water capacity and pure water quality is different.
That is reason we feel low pure water capacity in the winter, but higher in the summer.
Lab test condition : feed water pressure: 70 psi. work temperature: 77 F or 25 C. Nacl concentration: 250 ppm. recovery: 15%.
