RO water purifiers that actually make you want to drink more water

Most of us don't give a second thought to the water we drink until it starts tasting weird, smells metallic, or mysteriously triggers the “Delhi belly” effect. That's when a trusty RO water purifier turns from an optional kitchen accessory into a full-blown household hero.

But with a flood of options on the market, how do you pick the right one? I dug into five models that claim to tackle everything from questionable tanker water to stubborn borewell minerals—and more. Here's what stood out, what impressed, and what left us wishing for just a bit more.

Top 5 RO Water Purifiers

KENT Supreme Alkaline: The Overachiever in a Compact Shell

If water purifiers went to college, the KENT Supreme Alkaline would graduate with honours and an extra certification. Boasting a seriously impressive RO + UV + UF + Alkaline + TDS Control + UV LED tank lineup, this purifier means business. It even has an auto-flush function, which feels like a neat little janitor is cleaning it from the inside, silently and tirelessly.

The 8-litre tank and 20 litres/hour flow rate easily keep pace with high-demand households, whether you're a joint family of five or just love hosting chai-samosa parties.

Why we liked it:

• Fast purification and a solid filtration combo
• Alkaline water adds a subtle taste boost
• Auto-flush is a thoughtful touch

What’s missing:

• Design is functional, not flashy. Don’t expect compliments on your kitchen aesthetic.

Havells Fab Alkaline: The One That Looks as Good as It Works

In a sea of bulky plastic boxes, the Havells Fab Alkaline stands out like that one well-dressed guest at a casual get-together. With its stylish white and sky-blue finish, this 7-litre beauty doesn't just purify—it adds to your kitchen’s decor.

It packs a 7-stage purification system and replenishes essential minerals like copper, zinc, and others that often get stripped away during RO purification. It also comes with a filter alert system, so you’re never awkwardly pouring water from a nearly-dead filter while hosting guests.

Why we liked it:

• Elegant design that doesn’t scream "industrial equipment"
• Mineraliser adds back the good stuff
• Filter alerts are genuinely useful

What’s missing:

• Slightly lower capacity could be a concern for larger families

Aquaguard Delight NXT Aquasaver: The Eco-Warrior

If you're the kind of person who can't help but feel a little guilty every time you leave the tap running, the Aquaguard Delight NXT Aquasaver might be your spirit purifier. It promises to save up to 60% more water than traditional systems, which is honestly refreshing—pun intended.

Featuring 9-stage purification, this model handles RO + UV + UF + MC technology and comes with a taste adjuster, which sounds like a gimmick until you move cities and discover your new tap water tastes like a swimming pool. This model adapts, and that’s a huge win.

Why we liked it:

• Impressive water-saving feature
• Taste adjuster is handy when dealing with shifting water sources
• Compact design works in tight kitchens

What’s missing:

• No real-time display or alerts for filter status

AQUA D PURE 4-in-1 Copper RO: The Tanker Slaye

Some purifiers whisper filtration. The AQUA D PURE 4-in-1 Copper RO shouts it, and rightly so. With a whopping 12-liter tank, this is your best bet when relatives show up unannounced or your house becomes the unofficial party venue.

This purifier runs on a 10-stage filtration system—yep, ten—which includes RO, UV, UF, and TDS adjustment. Add copper infusion for that traditional Indian health twist, and you've got a system built for battle—whether it's weird-tasting borewell water or tanker supply that smells like regret.

Why we liked it:

• Huge tank means less frequent refills
• Copper tech adds that Ayurvedic vibe
• TDS control ensures consistent quality

What’s missing:

• Bulky design might not fit smaller kitchen spaces

Pureit Vital Plus Mineral RO+UV+MP: The Space-Saving Performer

If your kitchen has just enough wall space for a clock and a calendar—and both are already in use—the Pureit Vital Plus is for you. This 7-litre, wall-mounted purifier doesn’t just fit into tight spots, it thrives there.

Its 6-stage purification gets the job done efficiently, and it even saves up to 60% of water in the process. The highlight? FiltraPower technology, which sounds like a superhero power and pretty much is if you’re battling dodgy tap water.

Why we liked it:

• Great for compact kitchens
• Eco-conscious design with solid filtration
• Looks sleek, performs reliably

What’s missing:

Lower capacity might not suit large or frequent use households

Final Thoughts: Hydration, but Make It Smart

All five of these RO water purifiers bring something different to the table—whether it's monster-sized tanks, stylish designs, or water-saving tech. And in a time when water quality can swing wildly from city to city (or street to street), having a reliable purification system isn’t just about convenience—it’s about peace of mind.

If you want high flow and all-in-one features, go for KENT Supreme Alkaline. Need something stylish and space-conscious? Havells Fab or Pureit Vital Plus might suit you better. And if you want to save water while keeping taste consistent, Aquaguard Delight NXT offers the right mix of conscience and convenience.

Because in the end, what’s more refreshing than clean water, other than not having to worry about where it came from?
