What's the best gravity water purifier to buy in India?
The KENT Gold Gravity Water Purifier is our top pick because its listing states a 20L storage tank, a hollow fiber ultra filtration membrane with nano-silver carbon, a membrane expected to last up to 4000 litres, an unbreakable ABS food-grade plastic tank and a 1 year warranty. Aquaguard's Amrit+ 6000 suits shoppers who want an Aquaguard gravity purifier: its listing states 21L storage, 4-stage filtration, auto shut-off and a cartridge rated for up to 6000 litres.
India’s BIS drinking-water standard, IS 10500, sets the acceptable limit for total dissolved solids (TDS) at 500 mg/L — relaxed to 2000 mg/L only where no better source exists — with an acceptable pH range of 6.5–8.5; a purifier’s job is to bring your source water within these limits. BIS IS 10500:2012 (opens in new tab)
For the largest stated storage, the Pureit Classic lists 23 L; for a stainless steel body, the Home-Pro lists 21 litres with two ceramic candles. This guide compares five gravity water purifiers from KENT, Aquaguard (Eureka Forbes), Pureit and Home-Pro, using what each listing states: storage, purification method, filter life, auto shut-off and warranty. Stated storage runs from 15L (Aquaguard Amrit 4000) to 23 L (Pureit Classic).
KENT Gold Gravity Water Purifier 20L

The two Aquaguard listings state storage, filtration stages, cartridge life in litres and months, auto shut-off and a 6-month warranty, but no tank material. The Pureit and Home-Pro listings state no warranty term, and the Home-Pro listing states no filter life.
