Premium 5-Stage Under-Sink Water Filtration Replacement Kit

Unlock the potential of your water with this comprehensive, high-performance filter set. Designed as a universal replacement for standard 5-stage under-sink systems, this kit ensures your family has access to ultra-clean, great-tasting water every day.

Complete Set Features:

• Sequential Filtration: An optimized order from sediment to post-carbon for maximum efficacy.

• 0.01 Micron Ultrafiltration: The UF membrane provides powerful protection against microscopic contaminants.

• Includes Scale Inhibition: The RFC Resin stage is crucial for areas with hard water, protecting your appliances.

• High-Capacity Cartridges: Sized for an annual or near-annual replacement cycle (depending on usage).

Step-by-Step Breakdown and Individual Image View

Below is a detailed look at each stage of the filtration process, accompanied by an individual, close-up image of the specific cartridge included in this kit.

Stage 1: PP Cotton Filter Element

Function: Initial sediment removal. This high-density polypropylene cotton filter is the first line of defense, trapping sand, rust, silt, and large suspended particles.Lifespan: 3-6 months.Individual View:

Stage 2: CTO Compressed Carbon Filter

Function: Chlorine and organic adsorption. The CTO (Chlorine, Taste, and Odor) cartridge uses compressed activated carbon block technology to effectively remove chemical contaminants, improve taste, and eliminate odors.Lifespan: 8-12 months.Individual View:

Stage 3: RFC Resin Filter Element

Function: Water softening and scale inhibition. The RFC (Resin Filter Cartridge) contains ion-exchange resin that targets calcium and magnesium ions. By reducing water hardness, it prevents limescale buildup in your pipes, faucet, and the subsequent UF membrane.Lifespan: 8-12 months.Individual View:

Stage 4: UF Ultrafiltration Membrane

Function: Ultra-fine sub-micron filtration. The heart of the system. This UF membrane has a nominal filtration rating of 0.01 micron, capable of filtering out bacteria, cysts, and microscopic particles that standard carbon filters cannot miss. It provides powerful microbiological protection.Lifespan: 12-24 months.Individual View:

Stage 5: T33 Post Activated Carbon Filter

Function: Final polishing and taste enhancement. The T33 cartridge contains granular activated carbon (GAC) made from high-quality coconut shells. It serves as the final polishing stage, removing any residual taste or odor that may have been picked up, delivering pristine, crisp-tasting water.Lifespan: 8-12 months.Individual View:
