Brand: Aquaguard
Aquaguard's best-selling all-rounder, now with active copper
Our editorial score
Outstanding — a top pick in its class
Buyers who value service reliability and compact design over maximum tank capacity.
The Delight NXT is what I recommend to people who have been burned by bad service. Purification-wise it is closely matched with the KENT Grand Plus — same 2,000 ppm ceiling, same core stages — so the decision comes down to two things: tank size and who shows up when it breaks. KENT gives you 9 litres; Aquaguard gives you 6 litres and Eureka Forbes' direct field force, which in my experience is the most dependable in Indian appliances.
It is also simply a nicer object. The footprint is smaller, the finish is better, and it does not look like laboratory equipment bolted to your kitchen wall. Against that, five-year consumable costs run higher, and the 6-litre tank is a real constraint if your area gets long water cuts — you will find yourself waiting for it to refill.
Ignore the 'e-boiling' branding. It is a UV lamp, and a good one, but nothing is being boiled. Judge it on the RO+UV+UF stack, which is genuinely strong.
Every condition below is derived from this product's published specifications and from how it compares with the water purifiers we track — so you can check each one against your own room, supply or budget rather than take our word for it.
Your supply runs above 2,000 ppm TDS
The membrane is rated to 2,000 ppm. Feed it more and it will not fail dramatically — it will die early and quietly, and you will be buying membranes annually. Check your worst-season reading, not your average one.
Purifiers for high-TDS supply →Water wastage matters to you
The brand does not publish a recovery figure, so there is no way to know how many litres go to drain per litre purified. Only 2 of the 26 water purifiers we track publish this at all.
High-recovery purifiers →Low running cost is a priority
Consumables and routine service run about ₹4,200 a year, which is in the most expensive quarter of the water purifiers we track. Over five years that puts total ownership near ₹38,990.

Specifications are from manufacturer literature and were checked at the last price-verification date. Brands occasionally revise stage counts, tank sizes and warranty terms without changing the model name — confirm against the current listing before purchasing.
India's oldest water purification brand and still the service benchmark — Eureka Forbes' direct technician network is the deepest in the category. The current Delight NXT / Aura / Ritzy line-up leans on mineral guard technology, active copper and e-boiling claims, with better industrial design than KENT.
