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.
