The membrane normally lasts about 2-3 years depending on your source water quality. - 400 GPD RO membrane with a high 97% stabilized salt rejection rate. Hundreds of impurities are reduced by over 99% through the 0.0001-micron TFC membrane layer, including heavy metals (fluoride, calcium, magnesium, lead, colloids, chromium, and nitrates), organic materials, and harmful minerals, including other soluble salts found in water resources. - MS Reverse Osmosis (RO) membranes are made from 100% food-grade Thin Film Composite (TFC) material for ultimate purification performance with high permeate flow, tested by an independent third-party to meet NSF/ANSI 58 standards - Tips: Recommend work pressure is 100 psi when using this product in a Maple Syrup reverse osmosis system. And we suggest heating and maintaining the raw sap at 104°F(40°C) to prevent clog on the membrane while keeping it under 113°F(45°C) to avoid damage to the membrane due to over-high temperature. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071SGLF18 | | Brand | Membrane Solutions | | Compatible Water Purifier Models | APEC Water Systems ROES-50, iSpring RCC7 | | Customer Reviews | 4.5 4.5 out of 5 stars (44) | | EU Spare Part Availability Duration | 2 Years | | Enclosure Material | ro membrane | | External Testing Certification | NSF | | Global Trade Identification Number | 00850071881868 | | Item Dimensions D x W x H | 7.6D x 7.6W x 30.5H Centimeters | | Item Weight | 454 g | | Manufacturer | ir | | Manufacturer Part Number | unknown | | Model number | ROULP-3012-400 | | Number of Items | 1 | | Number of Packs | 1 | | Product Benefits | Reduces over 99% of impurities and contaminants for clean and safe drinking water | | UPC | 850071881868 | | Unit Count | 1.0 Count | ## Product Details - **External Testing Certification:** NSF - **Item Weight:** 454 g - **Material:** ro membrane - **Product Benefits:** Reduces over 99% of impurities and contaminants for clean and safe drinking water - **Product Dimensions:** 7.6D x 7.6W x 30.5H Centimeters ## Images ![Membrane Solutions RO Membrane, 400 GPD Reverse Osmosis Membrane, 3.0"x12" Water Filter Replacement for Under Sink Home Drinking RO Water Purifier System - Image 1](https://m.media-amazon.com/images/I/51xGrsk-ZjL.jpg) ![Membrane Solutions RO Membrane, 400 GPD Reverse Osmosis Membrane, 3.0"x12" Water Filter Replacement for Under Sink Home Drinking RO Water Purifier System - Image 2](https://m.media-amazon.com/images/I/41O6KmwXgQL.jpg) ![Membrane Solutions RO Membrane, 400 GPD Reverse Osmosis Membrane, 3.0"x12" Water Filter Replacement for Under Sink Home Drinking RO Water Purifier System - Image 3](https://m.media-amazon.com/images/I/51RukIwMy0L.jpg) ![Membrane Solutions RO Membrane, 400 GPD Reverse Osmosis Membrane, 3.0"x12" Water Filter Replacement for Under Sink Home Drinking RO Water Purifier System - Image 4](https://m.media-amazon.com/images/I/51TX3OvzsJL.jpg) ![Membrane Solutions RO Membrane, 400 GPD Reverse Osmosis Membrane, 3.0"x12" Water Filter Replacement for Under Sink Home Drinking RO Water Purifier System - Image 5](https://m.media-amazon.com/images/I/515Pg93+SZL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Frequently Bought Together - Membrane Solutions RO Membrane, 400 GPD Reverse Osmosis Membrane, 3.0"x12" Water Filter Replacement for Under Sink Home Drinking RO Water Purifier System - Membrane Solutions 3012 RO Membrane Housing Kit, Universal for Semi Commercial 200/300/400 GPD Reverse Osmosis Water Filter Systems, RO Filter Housing Wrench Fittings Set - PUREPLUS 5 Micron 10" x 2.5" Whole House Sediment Home Water Filter Cartridge Replacement for Any 10 inch RO Unit, Culligan P5, Aqua-Pure AP110, Dupont WFPFC5002, CFS10, WHKF-G05, 4Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/399206536-membrane-solutions-ro-membrane-400-gpd-reverse-osmosis-membrane-3](https://www.desertcart.be/products/399206536-membrane-solutions-ro-membrane-400-gpd-reverse-osmosis-membrane-3) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-27*
