• Removes sand, rust, dirt, and large particles.
• Protects other filters from clogging.
⸻
🧪 Stage 2 – Pre-Carbon Filter
• Removes chlorine, bad taste, and odors.
• Protects the RO membrane from chlorine damage.
⸻
🧵 Stage 3 – Fine Sediment / Carbon Block
• Removes smaller particles.
• Further reduces chemicals and organic compounds.
⸻
🔬 Stage 4 – RO Membrane (Main Stage)
• The most important stage.
• Removes:
• Dissolved salts (TDS)
• Heavy metals (lead, arsenic)
• Fluoride
• Nitrates
• Bacteria and viruses
• Works by pushing water through a semi-permeable membrane.
• Produces purified water + some wastewater.
⸻
🧂 Stage 5 – Post Carbon Filter
• Improves taste and smell.
• Removes any remaining odor from storage tank.
⸻
⚖️ Stage 6 – Mineral Filter (Remineralization)
• Adds healthy minerals like calcium and magnesium.
• Improves taste and balances pH.
⸻
⚡ Stage 7 – Alkaline Filter (Optional in some systems)
• Raises pH slightly.
• Makes water less acidic.
⸻
🦠 Stage 8 – UV or UF Filter (Final Protection)
• UV light kills bacteria and viruses.
OR
• UF membrane blocks remaining microorganisms.
