Short answer: It depends on your water. On municipal water under 200 TDS, you don’t need an RO: the KENT Gold Plus gravity purifier (about ₹3,449) is the best buy under ₹5,000. On borewell or tanker water, you need an RO, and under ₹5,000 that means a smaller brand. The Aqua X Pure Grand Plus RO+UV+UF (about ₹4,250) has 12 litres of storage and auto flush. Check that the brand services your PIN code before you order. Prices checked on Amazon on 10 November 2026.
Big-brand ROs from KENT, Aquaguard and Livpure start around ₹8,000–10,000. Under ₹5,000, you have two honest choices. One is a well-made gravity purifier from a big brand, which handles germs but not dissolved salts. The other is an RO from a smaller brand, which handles everything but comes with thinner service and filters that can be harder to find.
Which is right depends on one number: your water’s TDS. A ₹300 TDS meter tells you in five seconds. Under about 200 ppm, the gravity route is better and cheaper to run. Over 300 ppm, you need RO, so read the small-brand section carefully.
What you give up under ₹5,000
| Option | Handles TDS? | Service | Running cost |
|---|---|---|---|
| Big-brand gravity (KENT, Pureit) | No | Excellent | Low |
| Small-brand RO | Yes | Varies by city | Moderate; filters may be harder to find |
| Big-brand RO | Yes | Excellent | Moderate, but costs ₹8,000+ |
With any small-brand RO, ask three questions before you buy: does it install in my PIN code, what does a filter set cost, and who services it after the first year? Installation is often extra. AQUA D PURE, for example, lists up to ₹499.

The 6 best water purifiers under ₹5,000
1. KENT Gold Plus (Gravity) – Best for municipal water
If your tap reads under 200 TDS, this is the smartest ₹3,449 you can spend on drinking water. KENT’s UF membrane catches bacteria and cysts, needs no electricity, and is rated for up to 4,000 litres. It has a 20-litre transparent tank.
It doesn’t reduce TDS or hardness. That’s fine on corporation supply, and not fine on a borewell.
Key specs

- 20 L storage
- Membrane life up to 4,000 L
- No electricity
What we like
- Big brand, cheap to run
- Works in power cuts

Buy it if: you’re on municipal water and want the best value.
2. Pureit Classic 23 L (Gravity) – Best filter lock
Pureit’s germkill kit stops water flowing when it’s exhausted, so no one can drink through a dead filter. That makes it the safest choice for elderly parents or tenants who may forget to change it. Each kit is rated for 3,000 litres.

- 4-stage with germkill kit
- 23 L
- Stops flow when the kit is exhausted

RO, UV and UF together, a 12-litre tank and auto flush, which rinses the membrane to help it last, all for about ₹4,250. It carries a 1-year warranty on electrical parts.
It’s a smaller brand, so check installation and service in your area and the cost of a filter set before you order.

- 12 L storage
- Auto flush
- 1-year electrical warranty
What we like
- Full RO protection under ₹5,000

Installation is listed as up to ₹499 extra, so budget for that.
Key specs
- RO + copper
- TDS adjuster
- 12 L storage

Buy it if: you need RO and every rupee counts.

Before you order
- Buy a TDS meter and test your kitchen tap

- Over 300 ppm: buy RO, and fit a ₹800 pre-filter to protect it
- For a small-brand RO, ask the seller about your PIN code, filter prices and service after the first year
Questions people ask us
Which water purifier is best for home under ₹5,000?
The KENT Gold Plus gravity purifier for municipal water, or the Aqua X Pure Grand Plus RO+UV+UF for borewell water.
Can I get a good RO under ₹5,000?
Yes, from smaller brands. The purification is similar, but service and filter availability vary by city, so check first.
Is a gravity purifier enough?
On low-TDS municipal water, yes. It won’t remove salts or hardness.
What’s the yearly running cost?
A gravity purifier usually needs one filter or kit a year. An RO needs a filter set every 9–12 months, and sometimes a membrane.
Bottom line
Test your water first. Under 200 TDS, buy the KENT Gold Plus and you’re done. Over 300 TDS with only ₹5,000 to spend, the Aqua X Pure Grand Plus is the best small-brand RO, but only after you’ve confirmed service in your area. If you can stretch to ₹8,000, see our borewell guide for big-brand ROs.
