OKK六級(jí)過濾：PP棉+精密碳棒+KDF活性碳+樹脂+顆粒碳+栽銀活性碳To filter by six step: PP cotton + KDF activated carbon + resin + granular carbon + CARTISThe 6 filter for the integral whole style water filter use the stainless steel crust that can used for food’s production, and use the ultrafiltration membrane as core filter material, with imported KDF, chosen coconut shell granular carbon, highly active negative ion activated particle, nanometer bacteriostasis far IR mineralize particle. clarified water tasted pure, sweet, safety and health. highly active negative ion activated particle change the structure of the water molecule in a way, and make the water alkalescent and easier for human’s absorb, nanometer bacteriostasis far IR mineralize particle can increase the water’s mineral composition. And it make the clarified water more nutritious and health.
