Combo Package 4 - 10" PP (120gm) + GAC + CTO Filter

Specifications of the Combo Package 4 - 10" PP (120gm) + GAC + CTO Filter

PP Filter (Polypropylene Filter)

• A high-density polypropylene filter designed for primary pre-filtration.
• Removes large, suspended particles like sand, dirt, rust, mud, silt, and other physical impurities.
• Manufactured using melt-blown technology, which provides graded density—coarser on the outside and finer inside—to increase efficiency and lifespan.
• Protects all downstream filters such as carbon cartridges and the RO membrane from premature clogging.
• Typically rated between 1 to 5 microns depending on the system’s requirement.

GAC Filter (Granular Activated Carbon Filter)

• A loose-filled activated carbon filter used for chemical and organic adsorption.
• Removes chlorine, pesticides, herbicides, phenols, VOCs, and dissolved organic compounds.
• Improves taste, color, and odor by reducing chemical contaminants.
• Offers a high porosity structure for faster flow rates.
• Protects the RO membrane from chlorine damage, which can reduce membrane performance.

CTO Filter (Carbon Block – Chlorine, Taste & Odor Filter)

• A compressed carbon filter providing better adsorption and filtration than GAC.
• Designed to remove chlorine, turbidity, fine particulate matter, and unpleasant taste/odor.
• The carbon block structure increases contact time, resulting in stronger chemical reduction ability.
• Also improves clarity by removing small sediments that escape pre-filters.
• Protects the RO membrane from chemical attack and enhances RO purification quality.
