If your home runs on municipal or tanker water and you either can't spare a power point or don't want the wastage and running cost of an RO, a non-electric gravity purifier is the honest answer — and the Pureit Classic 23L and KENT Gold Plus are the two that come up most for the query "best gravity based water purifier in India". Both sit under ₹3,500, both work purely on gravity with no electricity, gas or plumbing, and both are counter-top units you fill from the top. But they clean water in fundamentally different ways. The KENT Gold Plus uses an ultrafiltration (UF) hollow-fibre membrane — a physical barrier fine enough to hold back bacteria and cysts — backed by nano-silver carbon. The Pureit Classic is activated-carbon based with Pureit's programmed Germ Kill technology, which mainly improves taste and odour and targets germs rather than filtering them out by membrane. One important caveat for both: neither is an RO, so neither reduces dissolved salts or TDS. They are made for low-TDS municipal or tanker supply, not hard, high-TDS borewell water — for that you need an RO purifier. This comparison sorts out which of the two gravity units fits your kitchen.

Our verdict
Both the Pureit Classic and KENT Gold Plus are honest, non-electric gravity purifiers under ₹3,500 for homes on municipal or tanker water, and neither reduces TDS — so cross both off your list if you have hard, high-TDS borewell supply and buy an RO instead. Between the two, the split is clear. The Pureit Classic wins on value: about ₹2,999, a larger 23-litre tank, activated-carbon purification with programmed Germ Kill technology and a filter rated to 3,000 litres — the budget pick that mainly improves taste and reduces germs. The KENT Gold Plus wins on safety: its UF hollow-fibre membrane physically removes bacteria and cysts, nano-silver carbon adds disinfection, and the membrane lasts up to 4,000 litres. Choose Pureit Classic for the lowest price and biggest storage; choose KENT Gold Plus for the stronger microbiological barrier.

Editor's take
Buy the Pureit Classic if price and storage lead your list: at around ₹2,999 it is the cheaper of the two, holds a larger 23 litres, and runs with no electricity, gas or plumbing — a sensible, low-fuss pick for a family on treated municipal water who mainly want better-tasting, germ-reduced water without running an RO. Buy the KENT Gold Plus if microbiological safety is the priority: its UF hollow-fibre membrane is a physical barrier against bacteria and cysts, its nano-silver carbon adds disinfection, and its membrane lasts up to 4,000 litres — worth the extra few hundred rupees where your water arrives via tankers or open storage. Both are non-electric and neither reduces TDS, so if your supply is hard, high-TDS borewell water, skip both and buy an RO purifier instead.
Editor's read
The honest way to frame Pureit Classic versus KENT Gold Plus is by purification mechanism, because that is where they genuinely differ. The KENT Gold Plus runs water through a hollow-fibre ultrafiltration membrane — a physical sieve fine enough to hold back bacteria and cysts — plus nano-silver carbon for added disinfection, and its membrane is rated to last up to 4,000 litres. That makes it the safer microbiological choice for tanker or open-supply water. The Pureit Classic is activated-carbon based: it improves taste and odour, reduces chlorine and adds programmed Germ Kill technology, and it undercuts the KENT on price while offering a larger 23-litre tank and a filter rated to 3,000 litres. Neither reduces TDS, so both are strictly for low-TDS municipal or tanker water, not high-TDS borewell supply.

How we compared these
This head-to-head is researched from each product's published specifications, manufacturer documentation, expert reviews and the aggregate of genuine Indian buyer feedback — not hands-on lab testing. We weigh the specs that actually matter for Indian conditions (voltage variability, hard water, monsoon humidity, service-network reach) and tell you which contender suits which buyer, rather than claiming to have bench-tested either unit. We do not accept paid placements — our only commercial relationship is the Amazon affiliate link. See our full methodology.
What to look for
- 1Confirm your water is low-TDS before buying either: Both are gravity purifiers with no RO stage, so neither removes dissolved salts, hardness or heavy metals. They are meant for municipal or tanker water that is already reasonably low in TDS. If you are on borewell or hard, high-TDS supply, no gravity purifier will fix the taste or safety — you need an RO instead, so test your water's TDS first.
- 2Decide what your real risk is — germs or taste: A UF membrane like the KENT Gold Plus physically filters out bacteria and cysts, which matters if your supply is microbiologically suspect or arrives via open tanks and tankers. The Pureit Classic's activated carbon mainly polishes taste and odour and reduces chlorine, with programmed Germ Kill technology on top. If microbiological safety is the priority, the UF membrane is the stronger mechanism.
- 3Match storage to your household and counter space: The Pureit Classic holds 23 litres and the KENT Gold Plus 20 litres, and both are top-fill counter-top units. A larger tank means fewer refills for a bigger family but also a bigger footprint — measure your counter before you commit, since these gravity purifiers are not wall-mounted.
- 4Factor in filter and membrane life, not just the sticker price: The Pureit Classic's filter is rated for up to 3,000 litres and the KENT Gold Plus membrane for up to 4,000 litres. A longer-life element means fewer replacements over the years; budget for the eventual replacement kit as part of the true cost, and change it on schedule regardless of brand.
- 5Remember that no electricity is a feature here, not a limitation: Both run entirely on gravity — no power point, no pump, no addition to your electricity bill, and they keep working during outages. If your home has unreliable power or you simply don't want another appliance drawing current, that is a genuine advantage over any RO or UV purifier, both of which need electricity.

Frequently asked questions
Which is better — Pureit Classic or KENT Gold Plus?
It depends on what your water needs. The KENT Gold Plus uses a UF hollow-fibre membrane that physically filters out bacteria and cysts, making it the stronger choice for microbiological safety — useful for tanker or open-supply water — and its membrane lasts up to 4,000 litres. The Pureit Classic is activated-carbon based; it improves taste and odour and adds programmed Germ Kill technology, costs less (around ₹2,999) and holds a larger 23-litre tank. Both are non-electric gravity purifiers and neither reduces TDS. Choose Pureit Classic for price and storage, KENT Gold Plus for a stronger germ barrier.
Are gravity water purifiers good for borewell water?
Generally no. Both the Pureit Classic and KENT Gold Plus are non-electric gravity purifiers without an RO stage, so neither reduces dissolved salts, hardness or heavy metals — the things that make most borewell water hard or high in TDS. They are designed for low-TDS municipal or tanker supply. If your source is borewell or otherwise high-TDS water, a gravity purifier will not fix the taste or safety, and you should choose an RO purifier instead.
Do the Pureit Classic and KENT Gold Plus need electricity?
No. Both are non-electric gravity purifiers — you fill the top chamber and purified water collects in the storage tank below, driven entirely by gravity. There is no pump, no power point and nothing added to your electricity bill, and they keep working during power cuts. That is a genuine advantage over RO and UV purifiers, which both need electricity to run.
What is the difference between UF and activated carbon purification?
A UF (ultrafiltration) membrane, as in the KENT Gold Plus, is a hollow-fibre physical barrier with pores fine enough to trap bacteria and cysts, removing them by size. Activated carbon, as in the Pureit Classic, works differently — it adsorbs chlorine and organic compounds to improve taste and odour but is not a microbiological barrier on its own; Pureit adds programmed Germ Kill technology alongside it. Neither UF nor carbon reduces dissolved salts or TDS, which needs RO. For germ removal, the UF membrane is the more reliable mechanism.
