## 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, providing safe-clean drinking water.
- 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.
