150 GPD RO Membrane 12 x 2 in Replacement - High Purity Water

In this review the Membrane Solutions 150 GPD RO membrane is evaluated for home undersink reverse osmosis systems and maple syrup ro units. The bottom line: this 12 x 2 in Thin Film Composite element is for homeowners and small-scale syrup producers who want a high-flow, food-grade membrane that cuts hundreds of impurities and noticeably improves taste. It stands out because it combines a 150 GPD flow rate with a claimed 97% stabilized salt rejection and NSF/ANSI 58 testing, which makes it an easy direct replacement for many standard 1812/2012 housings.

Key Features

• 100% food-grade TFC: The Thin Film Composite material provides durable, safe filtration suitable for drinking water and food-contact applications.
• 150 GPD flow: The 150 gallons per day capacity gives steady permeate flow for typical undersink systems and light commercial uses like maple syrup concentration.
• High contaminant reduction: A 0.0001-micron membrane layer reduces hundreds of impurities by over 99%, improving water clarity and taste.
• 97% stabilized salt rejection: The high salt rejection rate helps lower total dissolved solids and heavy metals including fluoride and lead.
• Universal 12 x 2 in size: The industry-standard element fits standard 1812/2012 housings, making replacement straightforward for many systems.
• Dry-shipped, long life: Shipped sealed and dry, the membrane typically lasts 24 to 36 months depending on feedwater quality and operating conditions.

Who It's For

This membrane suits homeowners with standard undersink reverse osmosis systems who want a direct, cost-effective replacement that boosts taste and reduces dissolved solids. It is also a sensible choice for hobbyist maple syrup producers using RO concentration, provided they follow the recommended pressure and temperature guidance.

It is not for systems that require nonstandard membrane dimensions or specialized industrial membranes, nor for users who cannot meet the suggested operating ranges - for example, sap heating and pressure requirements in syrup production should be followed closely to avoid clogging or damage.

Pros & Cons

Pros

• Easy to install in standard 1812/2012 housings and fits many legacy systems.
• Noticeable improvement in water taste and clarity due to high contaminant reduction.
• Good value and long expected life of 24 to 36 months when feedwater is typical.
• Compatible with a wide range of commonly used membrane models and systems.

Cons

• Performance depends on feedwater quality, pressure and temperature, so results vary by installation.
• Requires correct pressure (and heat guidance for syrup use) to avoid clogging or damage in nonstandard applications.

Frequently Asked Questions

Will this fit my existing 1812 RO housing?
Yes, the element is the industry-standard 12 x 2 in size designed to fit standard 1812/2012 residential housings.

How long does the membrane typically last?
When installed in average feedwater conditions it is expected to last about 24 to 36 months; actual life depends on water quality, pressure and maintenance.

Can I use this for a maple syrup RO unit?
Yes, it is suitable for maple syrup concentration if operated at recommended pressures (around 100 psi) and sap temperatures (about 104F/40C, kept under 113F/45C).
