Filtration that actually filters
A single cartridge stacks ten media layers — PP cotton, bio-cotton, diatomite ceramic, coconut-shell carbon, silver-ion media, maifan stone, ion-exchange resin, high-density carbon, polypropylene felt and a washable ceramic core — reaching 0.1-micron precision. Each one is rated to treat 1,000 L (264 gal) before it is replaced.
