Aquaguard

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.

Strengths

  • Best-in-class direct service network with company technicians, not only franchisees
  • Genuinely good build quality and compact wall-mount footprints
  • Mineral Guard + Active Copper implementations are well executed

Watch for

  • Consumables cost more than KENT equivalents over a 5-year horizon
  • Model naming is confusing — Delight, Delight NXT and Sure Delight are different products

AO Smith

An American water-heating giant that brought serious engineering to Indian purifiers. AO Smith's Z-series is the benchmark for hot-water-on-tap RO, and its Advanced Recovery Technology genuinely delivers better reject ratios than most competitors. Premium pricing, premium build.

Strengths

  • Best hot-water RO implementation in India (Z9 and Z8 series)
  • Side-stream Advanced Recovery Technology cuts reject water substantially
  • Excellent build quality with proper food-grade tanks

Watch for

  • Among the most expensive mainstream options, both upfront and on AMC
  • Service network is thinner in tier-3 and tier-4 towns than KENT or Aquaguard

Frequently asked questions

Aquaguard or AO Smith — which brand is better?
Neither is universally better. Aquaguard: Best-in-class direct service network with company technicians, not only franchisees AO Smith: Best hot-water RO implementation in India (Z9 and Z8 series) On service reach — which matters more than most buyers realise — Aquaguard is stronger, rated excellent. In tier-3 and tier-4 cities, let service network decide; in metros, decide on the specific model.
Which brand has better service, Aquaguard or AO Smith?
Aquaguard, on our assessment — its network is rated excellent against good for the other. Verify for your own pin code though: call customer care, ask whether a technician covers your area, and ask how many days a filter-change request takes.
Which is cheaper to own, Aquaguard or AO Smith?
Aquaguard sits in the mid price band and AO Smith in the premium band. But purchase price is only part of it — compute five years of consumables and AMC before deciding, because two purifiers with the same sticker price can differ by ₹10,000 or more over that period.
