Membrane Solutions 100 GPD RO Membrane – 11.75 x 1.75-inch Replacement

Overview

The Membrane Solutions 100 GPD RO Membrane is a compact, undersink-ready element engineered for reliable home water purification. At 11.75 x 1.75 inches, it fits standard RO housings and pairs with many existing filtration systems to deliver steady performance without taking up extra space.

Why this membrane stands out

• 100% food-grade Thin Film Composite (TFC) material for safe, high-quality filtration.
• High permeate flow paired with strong impurity rejection for clearer water.
• 0.0001-micron filtration contributes to substantial reduction of dissolved solids in everyday use.

In real-world terms, this membrane blends efficiency with reliability. The combination of a compact size, robust rejection, and a broad compatibility range makes it a versatile upgrade for many undersink systems.

Specifications and compatibility

• Universal 11.75 x 1.75-inch size designed to fit standard 1812/2012 RO housings with 2-inch internal diameter.
• Compatibility includes popular membrane formats such as Dow Filmtec TW30-1812-100 and AXEON TF-1812-100 among others.
• Shipped dry in an original sealed package, ready for long-term storage until installation.

Longevity and care

• Typical life expectancy ranges from 24 to 36 months depending on feedwater quality, temperature, and pressure.
• Follow proper storage and handling, and install in a clean, properly pressurized system to maximize life.

Practical tips for best results

• For Maple Syrup reverse osmosis applications, a working pressure of around 100 psi is recommended.
• Keep raw sap temperature around 104°F (40°C) to minimize clogging, and avoid exceeding 113°F (45°C) to prevent membrane damage.

Whether you are upgrading an existing system or building a new undersink filtration setup, this membrane offers a balanced mix of flow, filtration quality, and compatibility. It presents a practical option for those seeking higher clarity and lower dissolved solids in daily water use, without overpromising performance. Consider it as a capable component in a broader filtration plan to meet your clean-water goals.
