LG

LG's purifiers are the premium engineering choice: stainless-steel tanks instead of plastic, dual-protection UV that sterilises the tank and the tap, and a self-sterilising cycle. If tank hygiene is your concern — and with Indian ambient temperatures it should be — this is the answer.

Strengths

Stainless-steel storage tank, which resists biofilm far better than plastic
Dual Protection Sterilising Care runs automatic UV cycles inside the tank
Excellent build and finish; the appliance actually looks premium

Watch for

Expensive, and consumables are priced like a premium appliance
Fewer models, so less choice of capacity and configuration

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

LG, 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, LG or AO Smith?

LG sits in the premium 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.
