Frequently asked questions

AO Smith or Havells — which brand is better?

Neither is universally better. AO Smith: Best hot-water RO implementation in India (Z9 and Z8 series) Havells: Best-looking mainstream purifiers, with corner and under-counter mounting options On service reach — which matters more than most buyers realise — Havells is stronger, rated very good. In tier-3 and tier-4 cities, let service network decide; in metros, decide on the specific model.

Which brand has better service, AO Smith or Havells?

Havells, on our assessment — its network is rated very good 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, AO Smith or Havells?

AO Smith sits in the premium price band and Havells in the mid 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.
