Membrane Solutions Reverse Osmosis Replacement Filter Kit — 2 Inline Filters & 2 × 50 GPD RO Membranes, Fits Under-Sink

High-Quality RO Membrane & Inline Carbon Filter — Consistent, High-Performance Water Purification

Product overview This reverse osmosis (RO) membrane and inline carbon filter combine food-grade, high-capacity materials with advanced membrane technology and automated spiral-wound fabrication to deliver reliable water purification. Designed for home RO systems, the components provide stable salt rejection, fine particulate removal, and easy, fast replacement for uninterrupted clean water.

Key features - Advanced RO membrane: Food-grade high-capacity material with spiral-wound construction for consistent performance and long-term stability.
- High stabilized salt rejection: Rated 50 Gallons Per Day (50 GPD) with 97% stabilized salt rejection to reduce dissolved salts and impurities.
- Ultra-fine filtration: Rejects particles down to 0.0001 micron, capable of removing up to 99% of more than 1,000 contaminants, including heavy metals (fluoride, lead, chromium, calcium, magnesium), nitrates, colloids, organics, and other soluble salts.
- Standard sizing & compatibility: RO membrane measures 11.75" x 1.75" and fits industry-standard 1812/2012 residential RO membrane housings (2" inner diameter). Inline carbon filter is 10" x 2" for common system compatibility.
- Easy inline installation: Inline carbon filter features 1/4" JG quick-connect fittings on both ends for direct connection to water lines — fast replaceability with no special tools.

Customer benefits - Cleaner, safer drinking water: Removes heavy metals, many dissolved solids, and a wide range of contaminants to improve water quality and taste.
- Reliable daily output: 50 GPD rating provides consistent flow for household needs while maintaining high rejection performance.
- Compatible with standard RO systems: Standard membrane and cartridge sizes make replacements straightforward and reduce downtime.
- Quick, tool-free filter swaps: 1/4" quick-connect inline filter simplifies maintenance and minimizes service time.

Technical specifications - RO membrane: 11.75" x 1.75", 50 GPD, 97% stabilized salt rejection, 0.0001 micron rejection threshold, spiral-wound construction, food-grade material.
- Inline carbon filter cartridge: 10" x 2", 1/4" (JG) quick-connect fittings on both ends.
- Housing compatibility: Fits standard 1812/2012 residential RO membrane housings with 2" inner diameter.

Simple inline filter installation (quick-connect) 1. Turn off the water supply to the RO system.
2. Remove the old inline filter.
3. Insert the 1/4" tubing into each end of the new inline filter, observing the flow direction arrow.
4. Turn the water supply back on and check for leaks.

This RO membrane and inline carbon filter pair is engineered to deliver high-purity water, straightforward maintenance, and broad compatibility with residential reverse osmosis systems.
