Specifications of the Combo Package 8 – 10″ PP (120gm) + GAC + CTO + RO Membrane + T33
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.
RO Membrane (Reverse Osmosis Membrane)
The heart of the purified water system, responsible for deep-level purification.
-
Removes up to 95–99% of dissolved solids (TDS).
-
Eliminates heavy metals (lead, arsenic, mercury), fluoride, nitrates, bacteria, viruses, and dissolved salts.
-
Uses semi-permeable membrane technology with a pore size of 0.0001 microns, allowing only pure water molecules to pass.
-
Essential for producing microbiologically safe and chemically purified drinking water.
Taste and Odor Filter/T33 (Post Carbon / Polishing Filter)
The final refinement stage before water reaches the faucet.
-
Removes any remaining unpleasant taste, odor, or residual gases after RO purification.
-
Ensures clean, refreshing, and crisp-tasting water.
-
Often uses coconut-shell carbon for superior polishing performance.
-
Guarantees the highest quality water right before consumption.
