Water Purifier Buying Guide for Indian Homes
RO vs UV vs UF — Which Do You Need?
RO (Reverse Osmosis) removes dissolved salts, heavy metals, and TDS — essential if your water has TDS above 300 ppm (common in North and West India). UV kills bacteria and viruses. UF (Ultrafiltration) removes suspended particles and cysts without electricity. For most Indian homes, RO+UV+UF is the minimum you should buy.
What TDS Level is Safe to Drink?
As per BIS standards, drinking water TDS should be between 50–150 ppm. Below 50 ppm, the water may be too pure (lacking minerals). Above 500 ppm is considered unsafe. A good RO purifier with TDS controller maintains the ideal range.
How Much Storage Capacity Do You Need?
For a family of 2–3 people, 7–8L is sufficient. For 4–6 people, opt for 10–12L. The AquaDart and iSpring models in this list both offer 12L storage, making them ideal for larger households.
Why Does Annual Maintenance Cost Matter?
Every RO purifier requires filter changes every 6–12 months. This costs ₹1,500–₹3,500/year depending on the brand. Trusted brands like Pureit (HUL) offer AMC packages. Factor this into your total ownership cost.
Frequently Asked Questions
Which is the best water purifier under ₹15000 in India in 2025?
The Proven Nexon Aqua (₹5,647) is our top pick for its 7-stage purification, Copper enrichment, and outstanding 4.8★ rating. For a trusted brand with nationwide service, the Pureit Wave Plus from HUL is the safest choice.
Is RO water safe for daily drinking?
Yes — especially models with a TDS controller that retains essential minerals like calcium and magnesium. Without a TDS controller, RO water can be too pure and may lack important minerals over time.
Do I need a plumber to install a water purifier?
Most wall-mounted RO purifiers require basic plumbing for the inlet connection. Amazon typically includes installation support with most water purifier purchases. Check the product listing for installation details.
What is the ideal water purifier for hard water in India?
For hard water (high TDS borewell water common in Delhi, Rajasthan, Gujarat), you need an RO purifier with TDS controller. All four models in this list are suitable for hard water.
