The short answer
Both of these are RO purifiers, so they share the stage that actually makes your water safe — the RO membrane that reduces dissolved salts and TDS.

Both of these are RO water purifiers, so the real question isn't which one cleans your water — it's whether the copper stage is worth paying extra for. The KENT Supreme Plus Alkaline+Copper RO stacks a copper and alkaline stage on top of a multi-stage RO+UV+UF system with an 8-litre tank, TDS Control and Auto Flush, aimed at buyers who specifically want copper-infused water. The Aquaguard Sure Delight RO+MC does the same essential job — reducing dissolved salts and TDS through an RO membrane, plus RO Maxx, Sedi Shield and a Particulate Filter for bacteria and virus reduction — at roughly half the price, without the copper stage. The honest framing matters here: the part that actually makes your water safe to drink is the RO membrane, and both purifiers have it. The copper stage is a taste-and-wellness add-on, not a purification upgrade. This comparison lays out where the copper model justifies its premium and where the regular RO gives you the same core safety for less.

Pros & cons

- +Claims 30x better dust and dirt removal and 10x more chemical protection than local purifiers
- +One-year free warranty plus an Aquaguard service plan worth ₹2,000 with unlimited repair visits
Cons

Our verdict
Both of these are RO purifiers, so they share the stage that actually makes your water safe — the RO membrane that reduces dissolved salts and TDS. That's why, for most buyers, the Aquaguard Sure Delight RO+MC is the smarter spend: at around ₹7,999 it delivers the same core RO purification plus RO Maxx, Sedi Shield and a Particulate Filter for bacteria and virus reduction, with a one-year warranty and a ₹2,000 service plan. The KENT Supreme Plus Alkaline+Copper RO earns its roughly ₹15,599 price only if you specifically want copper-infused, alkaline water and value the extra stages, TDS Control and 8-litre stored tank — because the copper stage is a taste-and-wellness add-on, not a purification upgrade. The right pick depends on your needs: choose the Aquaguard for the same essential safety at the best value, and the KENT if copper-infused water is something you genuinely want and will pay a premium for.

Editor's take
Buy the Aquaguard Sure Delight RO+MC if you want clean, RO-purified water at the lowest sensible price — it does the core job the KENT does, reducing dissolved salts and TDS through an RO membrane, and adds RO Maxx, Sedi Shield and a Particulate Filter for bacteria and virus reduction, all for around ₹7,999 with a one-year warranty and a service plan worth ₹2,000. Buy the KENT Supreme Plus Alkaline+Copper RO if you specifically want copper-infused, alkaline water and value the extra stages, TDS Control and an 8-litre stored tank enough to pay close to double at around ₹15,599. Just be clear about what the extra money buys: the copper and alkaline stages are a taste-and-wellness upgrade, not a water-safety one, because the RO membrane that actually makes your water safe is in both purifiers. For most buyers the regular RO is the smarter spend; the copper model is for those who genuinely want copper in their water.
Editor's read
On the spec sheet the KENT looks like the bigger machine — RO+UV+UF plus alkaline, copper and TDS Control, an 8-litre tank, Auto Flush and an advanced RO membrane rated to remove Arsenic, Mercury, Lead, Fluorides and pesticides. The Aquaguard runs a simpler RO+MC setup with Sedi Shield, a Particulate Filter and RO Maxx, claiming 99.9999% bacteria and 99.99% virus reduction, at roughly half the price. But the decision isn't really 'more stages versus fewer'. Both purify water through an RO membrane, which is the stage that makes borewell or tanker water safe to drink — so on core safety they are much closer than the price gap suggests. The KENT's genuine differentiator is the copper and alkaline stage, which is a taste-and-wellness choice, not a safety one. The honest read: the KENT is worth it if you specifically want copper-infused water and the larger stored tank, and the Aquaguard is the better value if you just want dependable RO-purified water without paying for copper.

How we compared these
This head-to-head is researched from each product's published specifications, manufacturer documentation, expert reviews and the aggregate of genuine Indian buyer feedback — not hands-on lab testing. We weigh the specs that actually matter for Indian conditions (voltage variability, hard water, monsoon humidity, service-network reach) and tell you which contender suits which buyer, rather than claiming to have bench-tested either unit. We do not accept paid placements — our only commercial relationship is the Amazon affiliate link. See our full methodology.
What to look for
- 1Separate 'copper' from 'purification' in your head: the stage that removes dissolved salts, heavy metals and TDS from your water is the RO membrane — and both of these purifiers have one. The KENT adds a copper and alkaline stage on top; the Aquaguard doesn't. Copper-infused water is a taste and wellness preference, not a safety feature, so don't pay the premium expecting cleaner water — pay it only if you specifically want copper in your glass.
- 2Match the purifier to your water source and TDS: the KENT Supreme Plus is rated for borewell, tanker and municipal water, while the Aquaguard Sure Delight is meant for borewell and tanker water with TDS above 200 ppm and explicitly not for supply below 200 ppm. If your water is low-TDS municipal supply, check suitability carefully before choosing the Aquaguard. Getting this right matters far more than any copper claim.
- 3Weigh the price gap honestly: at roughly ₹15,599 the KENT costs close to double the Aquaguard's ₹7,999. That difference buys you the copper and alkaline stages, extra purification stages and an 8-litre stored-water tank — not better core RO purification. Decide whether copper-infused water and the larger stored capacity are worth an extra ₹7,000-odd to you.
- 4Look at stored capacity if your supply is intermittent: the KENT specifies an 8-litre tank at 20 LPH, useful if your water supply cuts out and you want purified water on hand. The Aquaguard's storage isn't specified in its listing, so if a large ready-to-pour reserve matters to you, confirm the tank size before buying rather than assuming.
- 5Factor in service and running cost over years: both brands ship a one-year service plan with free installation and unlimited repair visits, backed by large pan-India networks — KENT across 19,000+ pin codes and Aquaguard across 17,000+. An RO purifier's real cost is the periodic filter and membrane replacements over its life, so a responsive local service centre and honest AMC pricing matter more than the sticker price.
Also worth a look
A larger-capacity regular RO purifier
If you have a big family or unreliable supply, a regular RO with a bigger stored tank often matters more than a copper stage — prioritise storage capacity and RO membrane quality over copper claims.
A copper-infusion water bottle or pot
If copper-infused water is the only reason you're tempted by the pricier model, a traditional copper bottle or pot gives you that copper benefit for a fraction of the cost, while a regular RO handles the actual purification.
An RO purifier matched to your local TDS
Before choosing on copper, confirm your water's TDS level and pick an RO rated for it — suitability for your specific borewell, tanker or municipal supply affects water quality far more than whether a copper stage is present.
Frequently asked questions
Is a copper RO water purifier better than a regular RO?
Not for water safety. Both the KENT Supreme Plus Alkaline+Copper RO and the Aquaguard Sure Delight RO+MC clean water through an RO membrane, which is the stage that removes dissolved salts and TDS and makes borewell or tanker water safe to drink. The copper model adds a copper and alkaline stage on top, which is a taste-and-wellness feature, not a purification upgrade. So a copper RO is 'better' only if you specifically want copper-infused water — the core purification is the same.
Is a copper water purifier worth the extra money?
It depends on what you want. The KENT copper RO costs around ₹15,599 versus roughly ₹7,999 for the Aquaguard regular RO — close to double. That premium buys the copper and alkaline stages, extra purification stages and an 8-litre stored tank, not better core RO purification. If you specifically want copper-infused water and the larger reserve, it can be worth it; if you just want safe RO-purified water, the regular RO gives you the same essential result for far less.
Do both copper RO and regular RO reduce TDS?
Yes. Both purifiers use an RO membrane, which is what reduces dissolved salts and TDS in the water. The KENT adds a TDS Control feature and an Auto Flush that helps maintain the RO membrane's rejection over time, while the Aquaguard's RO Maxx stage handles the same core dissolved-salt removal. The copper stage on the KENT sits after purification and does not change how TDS is reduced.
Which water purifier should I buy for borewell water?
Both are rated for borewell water, so check the details. The Aquaguard Sure Delight is suitable for borewell and tanker water with TDS above 200 ppm and explicitly not for supply below 200 ppm, so it's a strong value pick for higher-TDS borewell water. The KENT Supreme Plus is rated for borewell, tanker and municipal water and adds copper, alkaline and an 8-litre tank. If your borewell TDS is above 200 ppm and you want the lowest price, the Aquaguard fits; if you want copper-infused water and more stored capacity, the KENT does.
