It consistently boosts sugar concentration, cutting boil time and fuel use. Even when pushed toward its upper performance limits, it continues to run reliably without major drop-off when the system is set up properly. The membrane cleans up very well and has held performance over multiple seasons with proper flushing and storage—definitely adds to its value. Customer service is also excellent. They were responsive and helpful with setup questions, which is a big plus when adapting this for sap instead of standard water use. Bottom line: Great performance, easy to maintain, long-lasting, and well-supported. I’d buy it again. Review: RO membrain - works well with my maple sugar setup. ## Features - Membrane Solutions ROULP-3012-400 reverse osmosis membrane for home drinking water treatment or maple syrup filter systems are among the most reliable and consistent elements in the industry. - With the industry-standard 12" x 3" size, this high capacity RO element fits most standard 3012 RO housing for the light commercial reverse osmosis water systems. - Our membrane elements are shipped dry in an original sealed package for convenient handling and long shelf-life. 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 | | Best Sellers Rank | #113,708 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #1,041 in Water Purifier Accessories | | Brand | Membrane Solutions | | Compatible Water Purifier Models | APEC Water Systems ROES-50, iSpring RCC7 | | Country of Origin | USA | | Customer Reviews | 4.7 out of 5 stars 42 Reviews | | 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 | | Material | ro membrane | | Model number | ROULP-3012-400 | | Number of Items | 1 | | 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 | | 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/81u6kiVxd0L.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/71+QqNDgrOL.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/71OaiITxFsL.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/71ilWg9r4-L.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable, durable, and great support for maple sap concentration *by B***S on 1 May 2026* I use the Membrane Solutions 400 GPD RO membrane for concentrating maple sap, and it’s been a strong performer.
