Why Is RO Filter Replacement Important?
RO filters remove dust, sediment, bacteria, viruses, heavy metals, pesticides, and other impurities. Over time they become clogged, reducing purification efficiency. Replacing filters on time helps maintain safe drinking water and protects your purifier.
Ignoring filter replacement can result in:
• Poor water taste
• Bad odor
• Reduced water flow
• Increased TDS
• Damage to the RO membrane
• Higher maintenance costs
• Expensive future repairs

Different areas of Ahmedabad receive either AMC/Narmada water or borewell water. Borewell water generally has higher TDS and hardness, which can reduce filter life. Areas such as Chandkheda, Gota, South Bopal, Science City, Nikol, Naroda, Odhav, Vastral, New Ranip, and Ghatlodia may require more frequent maintenance.
