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. Review: Higher capacity with great price. - Larger capacity RO membrane unit. Excellent replacement cartridge, excellent value. ## Features - 100 GPD RO membrane,Rejects impurities down to 0.0001 micron,Reduce Total Dissolved Minerals (TDS),Heavy metal,Arsenic,Lead,Mercury,Fluoride and more - High Quality - NSF/ANSI Standard 58 certificated.Polyamide film composite material,Brand:HIDROTEK - Universal Compatible-Standard size ( Membrane Dimensions: 11. 75" x 1. 75" ), Fits 1812/2012 residential RO membrane housings (2” Inner Diameter ) - Life Span-24 months or 35,000 Gallons pure water for most tap water (200-500 ppm),It depends on usage amount and feed water quality. - Friendly Design, Easy installation.

Excellent replacement cartridge, excellent value. ### ⭐⭐⭐⭐⭐ good filtration but a little slow *by M***F on April 3, 2024* my tap water is around 300ppm. I'm getting it down to 9ppm with these filters. I'm running two 100gpd membranes which is making about 140 gallons per day at my regulated 40psi of household pressure. I kinda wish i bought the 150gpd membranes so i could be closer to a true 200gpd. I'm sure if i hooked it up to my unregulated hose bib on the side of my house which is 80psi i would get that but last time i bought 150gpd membranes i had much higher ppm for my filtered water, so I'll stick with these for now. Biggest thing for me is they work and get me very close to 0ppm ## Frequently Bought Together - Geekpure Reverse Osmosis RO Membrane 100 GPD Water Filter Replacement-NSF Certificated (1) - Aquatic Life 10-Inch Sediment, Carbon Block and Mixed-Bed Color Changing Deionization Resin Filters, RODI Reverse Osmosis Deionization Water Filter Replacement Cartridges Kit --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/60518039-100-gpd-reverse-osmosis-membrane-water-filter-replacement-for-ro](https://www.desertcart.pl/products/60518039-100-gpd-reverse-osmosis-membrane-water-filter-replacement-for-ro) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-26*
