Best Water Purifier for Home in India (2026): RO vs UV Explained + 6 Picks
The short version
TL;DR: The best water purifiers for Indian homes on Amazon.in (prices checked 12 August 2026): Aquaguard Sure Delight NXT RO+UV (₹7,999, 4.3 stars, free service plan) is the best overall value, Pureit Wave Plus RO (₹7,799, 4.4 stars) is the highest-rated budget option, and KENT Grand RO (₹11,899, 4.3 stars) is the safe premium choice with the strongest service network.What type of water purifier does your home need?
The right purifier depends on your water source, not your budget. Municipal (tap) water needs at least RO+UV or RO+UV+UF. Borewell water - common in apartments and many cities - almost always needs RO because of high TDS (dissolved solids). If your TDS is above 500 ppm, a plain UV purifier will not fix the taste or hardness; you need RO. If your water is already low-TDS (some city supplies), a UV+UF purifier is cheaper and wastes less water.
Two more factors: water wastage (RO purifiers reject 20-50% of water - newer "water saver" models reduce this) and service availability. A purifier is a service-heavy appliance; buying a brand with local service (Aquaguard/ESSELL, KENT, Pureit) matters more than a slightly lower price from an unknown brand.

Prices and ratings from Amazon.in search results, fetched 12 August 2026. Cheaper unbranded RO units (₹4,000-5,500, e.g. Proven Nexon at 4.6 stars) exist but come with thinner service support - treat their ratings with caution.
Is the Aquaguard Sure Delight the best buy?
Aquaguard Sure Delight NXT (₹7,999, 4.3 stars) bundles RO+UV with a free service plan worth ₹2,000 - and Aquaguard (ESSELL) has the most widespread service network in India. That combination - known brand, real filtration tech, and service included - makes it the safest purchase in this category. The 4.3-star rating across a large review base confirms it works as advertised.
Is the Pureit Wave Plus better value at ₹7,799?
Pureit Wave Plus (₹7,799, 4.4 stars) is the highest-rated purifier in this price range. It adds a mineral cartridge to RO, which restores essential minerals stripped by RO filtration - a genuine differentiator for long-term health-conscious buyers. Pureit's service network is solid (Unilever-backed). If the Aquaguard's free service plan is not a factor for you, the Pureit's higher rating and mineral restoration make it the better buy.
Is KENT Grand worth the premium?
KENT Grand (₹11,899, 4.3 stars) is the premium default - KENT is the best-known purifier brand in India, with the deepest service presence, and their RO+UF+TDS control technology is proven. You pay a KENT premium over functionally similar Aquaguard/Pureit models, but you buy certainty: parts, service, and resale value. For a long-term appliance used daily by the whole family, that certainty has real value.
How do you choose between RO, UV, and UF?
- High TDS (borewell/hard water, over 500 ppm): RO, or RO+UV if you also want germ protection.
- Low TDS municipal water: UV+UF is enough and wastes no water.
- Uncertain source: RO+UV+UF is the complete package.
- Check your TDS first - a ₹300 TDS meter tells you which category you need before spending ₹8,000-15,000.
Should you worry about RO water wastage?
Standard RO purifiers reject 20-50% of input water, which matters where water is scarce or metered. Models like the Pureit Eco Water Saver (₹10,999) recover more water. If water availability is a concern in your area, prioritise a water-saver model - the higher price pays for itself in reduced wastage over years.
FAQ
Which water purifier is best for home use in India?
Aquaguard Sure Delight NXT RO+UV (₹7,999, 4.3 stars, free service) or Pureit Wave Plus (₹7,799, 4.4 stars) - both trusted brands with strong service networks at a sensible price.
Is RO necessary for purifying water in India?
For borewell or high-TDS water, yes - UV alone cannot remove dissolved solids. For low-TDS municipal water, UV+UF is sufficient and wastes no water.
Which brand is best for water purifiers in India?
KENT, Aquaguard (ESSELL), and Pureit have the strongest service networks. For most homes, Aquaguard or Pureit at the ₹8,000 price point beats a more expensive KENT of similar spec.
How often should a water purifier be serviced?
Every 6-12 months, depending on water quality. Filters need replacement (RO membrane roughly every 1-2 years, pre/post filters more often). This is why service availability matters when choosing a brand.
What is a good budget for a home RO purifier?
₹7,000-12,000 covers trusted-brand RO+UV purifiers (Aquaguard, Pureit, KENT entry models). Below ₹6,000 you are in unknown-brand territory with thinner service support.
