Watts Premier 50 GPD RO Membrane Replacement for Premier Standard RO Systems – 1-Pack

Upgrade your Watts Premier reverse osmosis system with the 50 GPD RO membrane replacement. Engineered to integrate with Watts Premier 4SV/4-Stage (WP500025), 5SV/5-Stage (WP500032), and Zero Waste (WP0950045) configurations, it enhances filtration performance while maintaining compatibility with established under-sink setups. Note that Quick Change RO systems are not supported by this membrane.

What this membrane does for your water

This advanced semi-permeable membrane targets a broad spectrum of impurities, helping to reduce total dissolved solids (TDS) and sodium. It also addresses a range of contaminants such as arsenic, lead, percolate, chromium, copper, and radium. With a filtration capability down to 1/10,000 of a micron, tiny particles that can affect taste and clarity are minimized, contributing to a cleaner, more consistent drinking water experience.

In practical terms, you may notice crisper flavors and clearer appearance in your tap water after installation, especially in areas with higher mineral content. The membrane’s design emphasizes reliability and steady performance, supporting your RO system’s overall efficiency without demanding additional setup steps.

Key benefits and features

• 50 GPD membrane rate designed for reliable under-sink filtration
• Reduces TDS and sodium, plus a wide range of contaminants
• Filtration down to 1/10,000 micron for refined purity
• Built-in check valve promotes efficient, consistent system operation
• Compact 1.8" diameter by 10.75" length fits standard housings
• Long-lasting performance with an estimated life of 2–5 years

Compatibility, installation, and maintenance

Designed to work with Premier RO systems, this membrane is compatible with 4SV/4-Stage (WP500025), 5SV/5-Stage (WP500032), and Zero Waste (WP0950045). It is not compatible with Quick Change systems. The built-in check valve helps maintain efficiency over time, and the installation is straightforward for users replacing an old membrane.

Material quality and engineering focus on long-term performance. Lifespan varies with local water conditions, usage patterns, and how often you replace filters in the RO system. Regular maintenance and following the manufacturer’s guidelines will help maximize the membrane’s effectiveness.
