Core Design Philosophy: 15 Layers, Targeted Purification for Global Water

Detailed Breakdown of the 15-Layer Filtration System

Stage 1: Pre-Filtration (Layers 1-4) — Block Large Particles & Protect Subsequent Layers

• Layer 1: PP Cotton Pre-Filter — Captures large particles (5-10 microns) such as sediment, sand, rust, and silt. This layer prevents these particles from damaging the more delicate inner layers, ensuring long-term filtration efficiency. Ideal for areas with aging water infrastructure, common in many regions around the world.
• Layer 2: Activated Carbon Fiber Layer — Adsorbs large organic molecules, residual chlorine, and unpleasant odors/tastes (e.g., the chlorine aftertaste common in tap water worldwide). It also removes volatile organic compounds (VOCs) from industrial runoff, a common contaminant in urban areas globally.
• Layer 3: Ceramic Pre-Filter — Features a porous structure that filters out fine particles (1-5 microns), including microplastics, bacteria, and algae. This layer adds an extra layer of protection, ensuring only clean water moves to the core purification stages.
• Layer 4: Ion Exchange Resin Pre-Layer — Begins the initial removal of hard water minerals (calcium, magnesium) and small amounts of heavy metals (e.g., lead, copper), preventing scale buildup and preparing water for deep purification.

Stage 2: Heavy Metal & PFAS Removal (Layers 5-11) — Core Purification for Global Safety

• Layer 5: Granular Activated Coconut Shell Carbon (GAC) Layer — A high-efficiency adsorption layer made from food-grade coconut shell carbon, which is highly effective at capturing PFAS (including PFOA and PFOS, the two most regulated PFAS compounds globally). This layer also adsorbs chlorine byproducts (e.g., trihalomethanes, THMs), a toxic byproduct of traditional chlorine disinfection. GAC is widely recognized as an effective tool for reducing PFAS in drinking water worldwide.
• Layer 6: Anion Exchange Resin Layer — Specifically targets PFAS molecules by attracting and binding to their negatively charged functional groups. This layer enhances PFAS removal efficiency, ensuring it meets strict global drinking water standards. It also removes other negatively charged contaminants, such as nitrates and sulfates, common in agricultural areas around the world.
• Layer 7: Heavy Metal Chelation Layer — Uses a specialized chelating agent that binds to heavy metals (lead, arsenic, mercury, hexavalent chromium, manganese) and prevents them from passing through the filter. Lead is a major concern globally due to old lead pipes, while arsenic contaminates tap water in many industrial regions. This layer ensures 99.9%+ removal of these toxic heavy metals, meeting strict global safety standards.
• Layer 8: Nanofiltration (NF) Membrane Layer — Features an ultra-thin membrane with a pore size of 0.001 microns, specifically designed to remove low-molecular-weight PFAS (a challenge for many filters) and heavy metal ions. This layer complements the GAC and anion exchange layers to achieve comprehensive PFAS removal, suitable for global water quality needs.
• Layer 9: Catalytic Carbon Layer — Oxidizes and breaks down residual PFAS and heavy metal compounds that may have escaped the previous layers. This layer uses a catalytic reaction to render these contaminants inactive, ensuring they cannot re-enter the water supply. It also reduces residual chlorine and its byproducts, further improving water taste.
• Layer 10: Ion Exchange Resin Deep Layer — Further removes heavy metals (e.g., aluminum, cadmium) and balances water pH, addressing the acidic or alkaline water conditions common in different regions worldwide. This layer also reduces water hardness, preventing scale buildup in the filter and in home appliances.
• Layer 11: PFAS-Specific Adsorption Layer — A proprietary layer designed to target and remove trace amounts of PFAS, including hard-to-capture compounds like PFHxS and GenX (HFPO-DA). This layer ensures that even trace levels of PFAS (below detectable limits) are removed, providing peace of mind for users worldwide.

Stage 3: Deep Purification (Layers 12-14) — Eliminate Trace Impurities & Ensure Safety

• Layer 12: Ultrafiltration (UF) Membrane Layer — With a pore size of 0.01 microns, this layer removes any remaining bacteria, viruses, and microplastics that may have passed through the previous layers. It also filters out residual colloids and proteins, ensuring the water is microbiologically safe — a key requirement for global drinking water standards.
• Layer 13: Activated Alumina Layer — Targets and removes trace amounts of arsenic (both As(III) and As(V)) and fluoride, contaminants that are prevalent in groundwater across the globe. Arsenic is linked to bladder, lung, and skin cancer, making its removal a top priority for water safety worldwide.
• Layer 14: Trace Contaminant Adsorption Layer — Removes residual organic compounds, pesticides, herbicides, and pharmaceutical residues (e.g., antibiotics) that may be present in tap water worldwide. This layer ensures no trace contaminants are left behind, exceeding strict global drinking water purity standards.

Stage 4: Final Polishing (Layer 15) — Enhance Taste & Ensure Quality

• Layer 15: Food-Grade Activated Carbon Polishing Layer — Removes any remaining odors, tastes, or residual contaminants, leaving the water crisp and refreshing. This layer also balances the water’s taste, eliminating the metallic aftertaste often associated with heavy metal removal and the chemical taste from chlorine. The result is water that meets the highest standards for both safety and flavor, perfect for drinking, cooking, and daily use in homes and businesses worldwide.

Why This 15-Layer System Is Ideal for Global Users

• Globally Compliant — Meets strict global drinking water standards for PFAS (PFOA, PFOS, PFHxS, GenX), heavy metals, and other contaminants. Backed by authoritative lab tests, it proves 99.9%+ removal of over 200 contaminants.
• Targeted for Universal Contaminants — Specifically designed to address the most common water issues worldwide: PFAS contamination, lead from old pipes, arsenic from industrial runoff, manganese in tap water, and chlorine byproducts.
• Long-Lasting & Cost-Effective — The 15-layer filter only needs to be replaced once a year, at a cost of just USD 8.8 per set — a fraction of the cost of other advanced filtration systems (which can cost $20-$1,000+). This makes advanced water purification accessible to all households and businesses worldwide.
• Easy to Maintain — No professional installation or complex maintenance required. Simply replace the filter once a year, and enjoy consistent, safe drinking water. The pre-filtration layers also protect the core layers, extending the filter’s lifespan and reducing long-term costs.
