💧 Water Purifier Buying Guide — India 2026
Check Your TDS First — Always
TDS (Total Dissolved Solids) determines which purifier you need. TDS under 200: UV purifier sufficient. TDS 200–500: RO recommended. TDS 500–2000: RO essential. TDS above 2000: industrial RO needed. Test your tap/borewell water TDS with a ₹300 TDS meter before buying any purifier in 2026.
RO vs UV vs UF — Explained Simply
RO membrane removes dissolved salts, heavy metals, bacteria, viruses — essential for high TDS areas. UV lamp kills bacteria and viruses without removing minerals — best for low TDS municipal water. UF (ultrafiltration) removes suspended solids and bacteria without electricity. The combination RO+UV+UF covers all contamination types.
Mineral Retention — Critical in 2026
Standard RO removes ALL minerals including beneficial calcium, magnesium, and potassium. Long-term consumption of zero-mineral water is linked to nutrient deficiency. KENT’s TDS Controller and mineral retention technology keeps 15–25% minerals in output — the correct approach for long-term health.
UV LED In-Tank vs Standard UV
Standard UV lamps only sterilize water during purification. KENT’s UV LED In-Tank keeps stored water bacteria-free 24/7 — critical because purified water can get re-contaminated in the storage tank over 6–8 hours. In India’s summer heat (above 35°C), tank re-contamination is a real risk. UV LED in-tank solves this completely.
AMC Cost Over 3 Years
RO purifiers need annual maintenance: membrane change (₹2,000–4,000), carbon filter (₹400–800), pre-filter (₹200–400). Total AMC: ₹3,000–6,000/year. Aquaguard’s 2-year filter life cuts your AMC in half. Always factor 3-year AMC cost into your buying decision — a ₹8,000 purifier with ₹5,000/year AMC costs more than a ₹18,000 purifier with ₹2,000/year AMC.
Service Network — Tier-2/3 Cities
KENT has 500+ service centers and technicians across India including tier-2/3 cities. Eureka Forbes/Aquaguard has 1,500+ technicians — widest in India. If you live in a city with limited service options, always choose KENT or Aquaguard over newer brands. RO purifier servicing is not optional — it’s required every 6–12 months.
