Quadruple-action filtration system with Precoat technology consisting of a 0,5 micron pleated microfiltration membrane made of high-surface-area polyethylene microfibers with a dedicated drain, combined with vegetable-based powdered activated carbon (PAC), Ag technology with bacteriostatic silver salts and controlled-release polyphosphates. The combination of these technologies ensures the production of crystal-clear ice enhancing brilliance and transparency. The mechanical filtration action retains impu
