Premier 1R-1Y-1B-1G RO-Pure Replacement Kit
The Premier 1R-1Y-1B-1G RO-Pure Push Button Replacement Filter Kit provides a comprehensive 4-pack designed for under-sink RO Pure (WP531411, WP531407) or Zero/Pure Plus (WP531517, WP531417) systems. Included are three filters and a membrane tailored to reduce tastes and odors while maintaining essential minerals. The kit uses color-coded, clearly labeled components to speed up changes, and the push-button release enables tool-free operation without switching off the water supply. Note: this kit does not fit Watts 1/4 Turn Kwik-Change RO systems.
Filters included: one 5-Micron Sediment Filter for dirt and rust removal; one 5-Micron Activated Carbon Pre-Filter for chlorine reduction; one Post-Filter; and one 50 GDP Membrane for lowering dissolved solids and contaminants like arsenic and lead. This setup is aimed at steady performance and convenient maintenance for households relying on a compact, efficient under-sink RO solution.
Watts Premier RO Pure Plus 4-Pack
The Watts Premier RO Pure Plus VOC 4-Pack is designed for under-sink RO Pure or Zero/Pure Plus systems. It combines a Sediment Filter, a Carbon Pre-Filter, a VOC Filter, and a 50 GDP Membrane to target sediments, chlorine, volatile organic compounds, and dissolved solids. The identification colors—red, yellow, silver, and green—assist quick recognition during replacements. The push-button release feature simplifies maintenance without interrupting water flow, supporting a clean-tasting, odor-free supply. This kit is not compatible with Watts 1/4 Turn Kwik-Change RO systems.
Key filtration benefits include reducing taste and odor issues, pulling out contaminants that affect water quality, and maintaining a balanced mineral profile for everyday consumption. The VOC-focused filter adds an extra layer for households worried about agricultural or household chemical exposure in tap water.
Aquasure Premier Series 4-Stage Bundle
This complete Stage 1 to Stage 4 replacement bundle is compatible with Aquasure Premier Series 4-Stage RO systems (AS-PR75A, AS-PR75A-BN). Stage 1 is a 5-Micron Sediment filter, capturing suspended solids, rust, and dirt to improve overall water clarity and protect downstream filters. Stage 2 is a Carbon filter designed to curb chlorine, VOCs, pesticides, odors, and bad taste. The kit aims to support reliable long-term performance and straightforward maintenance through standardized 11-inch filters that simplify replacements.
SimPure 5-Stage Replacement Kit
The SimPure 5-Stage Replacement Filter Set includes a 75 GPD RO membrane and five cartridge stages suitable for standard 10-inch, 5-Stage RO systems. The configuration emphasizes staged purification: sediment removal, carbon pre-filtration, VOC control, and final membrane treatment to lower TDS and contaminants. The product page features a direct linking path to the SimPure system, reflecting compatibility with common 5-stage RO installations. This set is designed for straightforward swaps that maintain system efficiency and water quality across daily use.
Membrane Solutions 5 Micron Filter Set
The Membrane Solutions 5 Micron 2.5″ x 10″ CTO Carbon Block Cartridge is presented as a compact cartridge set suitable for whole-house style filtration integrations. It is designed for compatibility with multiple systems like WFPFC8002 and WFPFC9001, offering a CTO carbon block stage that helps reduce sediment and chlorine-related issues. The 6-pack option provides flexibility for larger households or multi-filtering configurations, enabling extended maintenance cycles when paired with a compatible RO installation. Users should confirm fit with their specific RO model before purchase.
Buying Guide: Key Purchase Considerations
- System compatibility: Verify that the replacement kit matches your RO system’s model and stage configuration (e.g., 4-stage vs. 5-stage, 10-inch cartridges).
- Filtration goals: Prioritize kits that target both sediment and activated carbon for taste, odor, and chlorine reduction, plus a robust membrane for dissolved solids.
- Maintenance usability: Look for push-button releases, color-coded filters, and tools-free replacements for convenient servicing.
- VOC and chemical control: If your water source has pesticide or herbicide concerns, consider VOC-focused filters or extended stage filters for thorough purification.
- Replacement frequency and cost: Consider the overall kit cost and how often you’ll replace each cartridge to estimate ongoing maintenance budget.
- Brand and warranty: Choose reputable brands with documented compatibility and warranty terms to ensure long-term reliability.
- Space and installation: Confirm under-sink dimensions and any additional fittings required for a smooth retrofit or upgrade.
- Environmental considerations: Some filters use less waste water or lower energy profiles—evaluate efficiency if the RO system’s waste ratio matters.
