How Often Should You Replace Water Purifier RO & UV Filters?

Water purifiers are your family's frontline defense against bacteria, heavy metals, and high TDS water. But neglecting filter changes can turn your purifier into a breeding ground for contaminants.

Recommended Replacement Schedule:

• Pre-Sediment Filter: Every 3 to 6 months (especially in areas with high mud or rust in municipal/borewell water).
• Pre-Carbon & Post-Carbon Filters: Every 6 to 9 months to absorb chlorine, pesticides, and unpleasant odor.
• RO Membrane: Every 12 to 24 months, depending on your raw water TDS and daily usage.
• UV Lamp & UF Filter: Every 12 months for 100% bacterial disinfection.

How to test: Check your water TDS with a digital meter every month. If the output TDS exceeds 20% of your initial baseline, schedule an immediate filter servicing.
