How We Ranked These

1. KENT Grand Plus: Best for Most Families

₹18,000 approx (as of 14 October 2026) — street prices observed between ₹17,000 and ₹19,500 across sellers.

The Grand Plus is the RO purifier India keeps coming back to, and the reason is boring in the best way: it works on almost any water, it stores enough for a family, and Kent's service actually shows up. The 9-litre tank covers a family of four through a power cut, the 20-litre-per-hour flow rate means you are not waiting around for a glass, and the combination of RO, UV, UF, and a TDS controller handles borewell, tanker, and municipal supply alike.

Two features separate it from cheaper rivals. First, the UV LED inside the storage tank keeps purified water protected from bacteria while it sits — stored water in a plain tank can re-contaminate, and this is Kent's answer to that. Second, the Zero Water Wastage design recirculates reject water to the overhead tank instead of sending it down the drain, though it needs extra plumbing to do so.

Key Specifications

Pros

Cons

Who should buy: Families of 3–6 on borewell, tanker, or mixed water who want one purifier that just works for years.

Who should skip: Tight budgets, single-person households, and homes on low-TDS municipal water (under ~200 ppm) where a simpler UV+UF unit would do.

Bank offers: Check the Amazon listing for current bank instant-discount and no-cost EMI offers during the festival sale — these change by event and seller. The listing also shows exchange offers from time to time.

2. Aquaguard Delight NXT Aquasaver: Best for Saving Water

₹11,000 approx (as of 14 October 2026).

Every RO purifier wastes water — that is the physics of the membrane. The Delight NXT Aquasaver is Eureka Forbes' answer: its Aquasaver technology claims about 60% less reject water than ordinary RO systems. If you feel guilty watching litres go down the drain, or your housing society charges for water, this is the model that directly addresses that guilt.

Beyond water saving, this is a compact, well-thought-out machine. The 6.2-litre tank suits small families, the Taste Adjuster (MTDS) lets you tune the water so it does not taste flat, and the 2-in-1 Mineral Charge adds minerals back after RO. It is also one of Amazon's bestsellers in the category, which means parts and technicians are easy to find. Note the smaller tank: this is a 3–4 person purifier, not a joint-family workhorse.

Key Specifications

Pros

Cons

Who should buy: Small families and couples who want RO purification with the lowest water wastage, especially in water-scarce cities.

Who should skip: Large families, and borewell homes with very hard water where the smaller tank and 1-year cartridge will feel like a constraint.

Bank offers: Check the Amazon listing for current bank offers and no-cost EMI (EMI has been listed from around ₹334/month). Festival-sale coupons of ₹1,000 have appeared on this model — verify on the live listing.

3. Livpure GLO PRO++: Best for Tight Budgets

₹7,500 approx (as of 14 October 2026).

The GLO PRO++ is the value disruptor in this list: full 7-stage RO+UV+UF purification, a 7-litre tank, free installation, and a 4.1★ Amazon rating — for roughly the price of two months of bottled-water delivery. If your main question is "can I get safe RO water without spending ₹15,000+", this is the answer.

The purification chain is thorough: sediment filter, pre-activated carbon, anti-scalant cartridge, RO membrane, UV disinfection, ultrafiltration, and a silver-impregnated post-carbon filter that also improves taste. The taste-enhancer post-carbon stage is a thoughtful touch at this price — it removes the stale smell that cheap purifiers sometimes leave behind. The trade-off is the brand's service network, which is smaller than Kent's or Aquaguard's, and a build that feels its price in places like the tap.

Key Specifications

Pros

Cons

Who should buy: Budget buyers, renters, and small families who want genuine RO purification at the lowest honest price.

Who should skip: Anyone who wants premium service coverage in a small town, or who would rather pay more once than chase a technician later.

Bank offers: Check the Amazon listing for current bank offers and EMI options — at this price, no-cost EMI is usually available and makes the effective monthly cost trivial.

4. HUL Pureit Copper+ Mineral: Best for Copper-Infused Water

₹21,000 approx (as of 14 October 2026).

Pureit's Copper+ is the only purifier here built around a health idea rather than a plumbing idea: it doses your water with copper, the way storing water in a copper vessel does, using a patented Copper Charge system that claims 99.8% pure copper infusion in real time. If you grew up with a copper matka at home, this is the modern version of that habit — with RO purification attached.

The clever part is the dual dispensing. One tap gives you copper-charged RO water, the other gives plain RO water, so you are not forced into copper water for every use — cooking, baby formula, or guests who do not want it. A mineral enhancer cartridge adds calcium and magnesium back after RO, and SmartSense indicators warn you 15 days before the filter expires and stop dispensing if you ignore it. That last feature sounds annoying until you realise it prevents the most common RO sin: drinking through a dead filter.

Key Specifications

Pros

Cons

Who should buy: Health-conscious buyers who value copper-infused water and want the discipline of filter-expiry lockout.

Who should skip: Budget buyers, and anyone who dislikes even a hint of metallic taste in water.

Bank offers: Check the Amazon listing for current bank offers and no-cost EMI. At this price point, festival-sale bank discounts make the biggest absolute difference — a 10% instant discount here is worth more than on any other model in this guide.

5. AO Smith Z9: Best Premium Pick With Hot Water

₹23,000 approx (as of 14 October 2026) — prices vary by listing and seller, so confirm the live price.

The Z9 is the only purifier here that replaces another appliance: your electric kettle. One touch gives you hot water at 45°C (warm) or 80°C (hot) from a stainless-steel tank, plus ambient RO water — tea, baby food, soaking dal, a late-night hot water bottle, all without waiting for a kettle to boil. For a kitchen where hot water is a several-times-a-day ritual, that convenience adds up fast.

Underneath, the purification is serious: 8-stage RO with SCMT (Silver Charged Membrane Technology) as a second line of defence against microbes after the RO membrane, a patented side-stream membrane that pushes 100% of water through RO, and MIN-TECH mineraliser for taste. The high-recovery design claims roughly twice the water recovery of an ordinary RO unit, and the 10-litre tank is the largest here. The price is premium, and so is the AMC — budget ₹5,000–₹6,000 a year — but this is the most complete water station in the guide.

Key Specifications

Pros

Cons

Who should buy: Families of 5+ who drink hot water through the day, want the biggest tank, and are comfortable paying premium AMC for premium convenience.

Who should skip: Budget buyers, and homes on low-TDS municipal water where a basic RO (or even UV+UF) would do the same job for far less.

Bank offers: Check the Amazon listing for current bank offers and no-cost EMI. Given the price, a festival bank discount plus an exchange offer can move this by ₹2,000 or more — worth waiting a few days for if your current setup still works.

How to Choose the Best RO Water Purifier

  1. Test your TDS first. A ₹200 TDS meter saves you from buying the wrong machine. Below ~200 ppm, UV/UF is usually enough. At 200–500 ppm, go RO+UV. Above 500 ppm, you need RO+UV+UF with a TDS controller. Above 2,000 ppm, a domestic purifier is not the right tool at all.
  2. Match storage to your family — and your power cuts. A 6L tank is fine for 2–3 people with stable power. Families of 4+ or homes with frequent outages should get 8–10L, because the purifier cannot refill the tank without electricity.
  3. Understand RO+UV+UF vs RO+MF. UF (ultrafiltration) and MF (microfiltration) both polish water after RO; UF filters finer particles than MF. For most homes the difference is small — what matters more is whether the unit has UV (kills microbes) and mineral retention (keeps water healthy and tasty).
  4. Check the service network before the brand name. Ask neighbours which brand's technician actually turns up in your area. Kent and Aquaguard have the widest coverage; Livpure is thinner in smaller towns. A purifier with no service is an expensive water jar.
  5. Budget the AMC, not just the purchase. After the free service period, expect ₹2,000–₹6,000 a year in filters and AMC. Over five years, AMC can cost as much as the purifier itself — the "cheap" model with expensive cartridges is not cheap.
  6. Ask about reject water. Standard RO rejects a meaningful share of input water. If wastage bothers you, pick a water-saving model (Aquaguard Aquasaver, Kent Zero Water Wastage with plumbing, or AO Smith high-recovery) rather than a standard unit.
  7. Confirm warranty and installation in writing. Free installation, what the warranty covers (membrane? filters? electrical?), and whether a pre-filter is included should all be clear before you pay. The pre-filter alone is a ~₹1,200 surprise on some Kent models.

One more practical note: RO purifiers need a power point, a pressurised water inlet, and a drain for reject water. If your kitchen layout makes that awkward, sort the plumbing spot before the delivery arrives — the free installation visit goes much faster. The same "check the real running cost" thinking applies across appliances: our geyser guide and chimney guide use the same total-cost approach.

Best RO Purifiers Under ₹15,000 — Match It to Your Water Source

Under ₹15,000, the right purifier depends less on brand and more on your water source. Buying RO for low-TDS municipal water wastes money on filters; skipping RO for high-TDS borewell water leaves the water hard and salty.

Your water sourceTypical TDSWhat you actually need
Municipal / corporation supplyLow (under ~300 ppm)UV + UF is usually enough; RO is optional
Tanker / mixed supplyMedium (300–600 ppm)RO + UV + UF covers most cases
Borewell / groundwaterHigh (600+ ppm)RO is essential; check the membrane rating and TDS controller

Two costs buyers forget: annual maintenance (filters + membrane replacement, plus AMC if you take one) and water wastage (RO rejects a portion of input water — look for models with a higher recovery ratio if water is scarce in your area). Compare the picks above on storage capacity, filter-change cost, and service-network strength in your city before deciding on brand alone.

Frequently Asked Questions

Which RO water purifier is best in India in 2026?

For most Indian homes, the KENT Grand Plus is our top pick: 9-litre storage, RO+UV+UF with TDS control, UV LED in-tank protection, and Kent's huge service network. Budget buyers should look at the Livpure GLO PRO++, and water-savers at the Aquaguard Delight NXT Aquasaver.

Is this a real discount or was the price raised before the sale?

Check the price history, not the struck-through MRP. RO purifier MRPs are routinely inflated, so a "50% off" tag often just means the normal street price. Compare the current price against the 30-day prices in this guide: Kent Grand Plus around ₹18,000, Aquaguard Delight NXT around ₹11,000, Livpure GLO PRO++ around ₹7,500.

Which bank or card offers work with these RO purifiers?

Bank offers change with every sale event and vary by seller on the Amazon listing, so check the offer strip on the product page before checkout. No-cost EMI is commonly available on these purifiers. Stack a bank instant discount with any exchange or coupon offer shown on the listing for the lowest effective price.

Should I wait for the next sale to buy an RO purifier?

If your current water is visibly bad or high-TDS, buy now — waiting weeks for a few hundred rupees of extra discount is not worth drinking poor water. If your current setup works fine, the big festival sales (Great Indian Festival, Big Billion Days) usually bring the lowest prices of the year on Kent, Aquaguard and Livpure models.

Is the KENT Grand Plus worth buying in 2026?

Yes, for most families. It handles borewell, tanker and municipal water up to 2,000 ppm TDS, stores 9 litres, and comes with years of free service. The main reasons to skip it are a tight budget (the Livpure GLO PRO++ costs less than half) or a small household that does not need 9 litres of storage.

What TDS level needs an RO water purifier?

Test your water with a TDS meter first. Below about 200 ppm, UV or UF purification is usually enough. From roughly 200 to 500 ppm, RO+UV makes sense. Above 500 ppm, you want RO+UV+UF with a TDS controller. Above 2,000 ppm, a domestic purifier is not the right tool — you need a water-softening solution first.

How much does RO purifier maintenance cost per year?

Budget roughly ₹2,000 to ₹6,000 a year after the free service period ends, depending on brand and your water quality. Kent and AO Smith AMCs sit at the higher end (around ₹4,000–6,000), while Livpure and Aquaguard are typically cheaper. Hard or muddy water wears filters faster, so borewell homes pay more.

Does RO remove all minerals? Is RO water safe to drink?

A basic RO membrane strips most dissolved minerals along with the contaminants, which is why every purifier in this guide adds mineral retention back — a TDS controller, a mineraliser, or a copper/mineral cartridge. With mineral retention in place, RO water is safe and tastes normal. That is also why you should not buy a bare-bones RO unit without a mineral-retention feature.

Which RO purifier wastes the least water?

The Aquaguard Delight NXT Aquasaver is the water-saving pick here, with Aquasaver technology that claims about 60% less reject water than ordinary RO systems. The KENT Grand Plus recirculates reject water back to the overhead tank, but that needs extra plumbing. The AO Smith Z9 uses a high-recovery membrane that claims roughly twice the recovery of a standard RO unit.

Which RO purifier should I buy for borewell water?

For borewell water, pick a model rated for up to 2,000 ppm TDS with RO+UV+UF and a TDS controller — the KENT Grand Plus is the safest default. Also budget for a pre-filter at installation, because borewell sediment clogs RO membranes fast without one.

Can I install an RO purifier myself, or do I need a plumber?

Do not DIY it. RO purifiers need a pressurised water inlet, a drain line for reject water, and a power point, and a bad install causes leaks. Every model in this guide includes free standard installation by the brand — book it through the brand after delivery and let their technician handle the plumbing.

Final Verdict

For most Indian families, buy the KENT Grand Plus — it handles every water source, stores enough for a power cut, and has the service network to back it for years. If water wastage is your top concern, pick the Aquaguard Delight NXT Aquasaver; if budget is, the Livpure GLO PRO++ gives you real RO purification for around ₹7,500. And if you want the most complete water station with hot water on demand, the AO Smith Z9 is worth its premium.

Whatever you pick, test your TDS first, confirm the live price, and book the brand's free installation. Clean water is one purchase where the cheapest shortcut — a dead filter, a skipped pre-filter — costs more than the thing itself.
