BMP Noah Main Filter
The Main Filter is composed of different filtration materials arranged purposely (from top to bottom):
- Granular Activated Carbon – Further eliminates bacteria
- Coral Sand – Generates 20 essential minerals
- Silver Impregnated Granular Activated Carbon – Further kills bacteria
- Somelite – Produces water with pH of 7.3-8.5
The layering of the Main Filter ensures elimination of chlorine and chemicals, mineralization and balancing of minerals and elimination of bacterial growth.
