Bangalore's Water Problem
Bangalore homes get water from three very different sources: Cauvery supply (relatively low TDS, 100–200), borewell water (often 400–900+ TDS with hardness), and tanker water (unpredictable quality). Many apartments mix sources. This matters because the right purifier and service schedule depend entirely on your TDS — an RO purifier on low-TDS Cauvery water wastes water and strips minerals unnecessarily.
Typical Service Costs in Bangalore (2026)
Standard service/visit — ₹300–₹600
Pre-filter + carbon filter replacement — ₹800–₹1,500
RO membrane replacement — ₹1,200–₹2,500
Full filter set + membrane — ₹1,500–₹4,000
UV lamp replacement — ₹600–₹1,200
Annual maintenance contract (AMC) — ₹2,000–₹5,000
New RO purifier installation — ₹300–₹800 (often free with purchase)
Costs vary by brand and model; genuine filters cost more than compatible ones but protect the membrane.
How Often to Service
On borewell or tanker water, service every 3–4 months and replace filters every 6–8 months — high TDS and sediment clog filters fast. On Cauvery water, every 6 months is enough. Warning signs of overdue service: slow flow, changed taste, and the purifier's filter-change indicator. If your TDS is under 200, consider a UV + carbon purifier instead of RO — cheaper to run and no water wastage.
Choosing a Service Provider
Ask for a TDS reading of input and output water at every service — it's the only real measure of purifier health. Confirm whether filters are genuine or compatible, and what the AMC covers (filters, membrane, unlimited visits?). Find water purifier service in Bangalore on FindService.in.

Frequently Asked Questions
How much does water purifier service cost in Bangalore? ₹300–₹600 for a standard service; filter replacement is extra.
What does full filter replacement cost? ₹1,500–₹4,000 including the RO membrane, depending on the model.
How often should I service my purifier in Bangalore? Every 3–4 months on borewell/tanker water; every 6 months on Cauvery supply.
What is TDS and why does it matter? Total Dissolved Solids — it decides whether you need RO (high TDS) or just UV/carbon (low TDS).
Is RO necessary for Cauvery water? Usually not — Cauvery water is often 100–200 TDS, where UV + carbon suffices and avoids water wastage.
Is an AMC worth it? Yes for borewell-water homes — ₹2,000–₹5,000 covers filters and multiple services.
Why is my purifier's flow slow? Clogged filters or membrane — the most common sign of overdue service.
Are compatible filters safe? Quality varies; genuine filters last longer and protect the membrane — ask what brand is being installed.
How much water does RO waste? Typically 40–60% is rejected; some models recover more. Use reject water for cleaning or plants.
What output TDS should drinking water have? 50–150 is generally considered ideal; ask the technician to set the mineraliser accordingly.
