By technology · Patna
TDS and AQI figures on this page are indicative planning ranges compiled from publicly reported patterns for this city — not live readings. Actual values vary by locality, borewell depth and season. Test your own supply with a TDS meter (around ₹300), and get a laboratory analysis if you suspect arsenic, fluoride, nitrate or iron.
Patna needs RO, and the reason is a number rather than an opinion: local supply here typically measures 300-700 ppm TDS, drawn mainly from municipal supply blended with borewell water. Reverse osmosis is the only domestic technology that reduces dissolved solids — UV kills microbes and changes the reading by nothing, UF blocks particles and changes it by nothing. At Patna's levels, that makes RO the category rather than the upsell.
The specification that matters most here is the membrane's rated input TDS. For Patna we would buy 2,000 ppm rated, which covers the local range with the headroom you need for summer, when groundwater concentrates as the water table drops. Insist on a TDS controller too: without one, output lands flat and demineralised, and you cannot re-tune when the supply changes with the season.
Local water is moderately hard, so scale is a manageable rather than dominant problem in Patna — which keeps membrane life at the better end of the range and pre-treatment requirements modest.
Every major brand services Patna directly, so you can choose on specification and price here rather than on who has an engineer nearby — which is a luxury buyers in smaller cities do not have.
Scored against Patna's supply — 300-700 ppm TDS, moderate water.
The default recommendation for Indian borewell water
Copper RO at a price that undercuts everyone
Aquaguard's best-selling all-rounder, now with active copper
HUL's copper RO with an enforced filter-life cut-off
Service-first purifier with app-scheduled maintenance
High-throughput KENT for large families and small offices
Nine stages, copper and alkaline, aggressively bundled
Counter-top KENT with a UV-sterilised tank
Buy a membrane rated 2,000 ppm or better. Local supply runs 300-700 ppm and climbs through summer as groundwater concentrates — design for the top of that band, not the middle.
Mandatory at Patna's levels. It blends output to a palatable 60-120 ppm instead of a flat 25 ppm, and lets you adjust when your building switches between piped supply and tankers.
A legacy RO rejects three litres per litre purified. In Patna, where households routinely pay for tanker top-ups, a high-recovery design pays for itself on the water bill alone.
At 300-700 ppm, expect 18-24 months from a membrane rather than the number on the box. Change sediment and carbon pre-filters every six months — they are what protect the expensive part.
All major brands service Patna directly, so this is a tiebreaker rather than a gate. Still ask for the AMC rate in writing before you buy.

Whatever you buy from this list, the ownership experience in Patnawill be decided by servicing rather than specifications. Phone the brand's customer care with your Patna pin code before you order and ask how many days a filter-change request takes. More than two or three days is a reason to choose a different brand.
