Short answer: If your corporation water reads under 200 ppm on a TDS meter, skip RO. Buy the Aquaguard Sure Delight UV+UF 2X (about ₹7,422). It has a 2-year filter life, an extra sediment filter in the box, and wastes no water. For a big family, the KENT Ultra Storage UV (about ₹8,699) puts out up to 60 litres an hour. If your TDS is over 200, this page isn’t for you: read our borewell guide instead. Prices checked on Amazon on 10 November 2026.
Most people in big-city flats on corporation supply are sold an RO they don’t need. Municipal water in Mumbai, Bengaluru, Kolkata and much of Pune is usually low in dissolved salts. Its real risks are germs that get in through old pipes and dirty building tanks, plus some sediment. UV kills the germs. UF filters out cysts and fine particles. Neither throws away water, and both keep the minerals in.
An RO on that same water wastes two litres for every one you drink, and then often adds minerals back with a separate cartridge. The fix starts with a ₹300 TDS meter. If you read under 200 ppm, here are the purifiers to choose from.
UV, UF or both?
| Technology | What it removes | Wastes water? | Needs power? |
|---|---|---|---|
| UV | Kills bacteria and viruses | No | Yes |
| UF | Filters cysts, fine particles and many bacteria | No | No |
| UV + UF | Both of the above: the best choice for municipal water | No | Yes |
| RO | Dissolved salts, hardness, heavy metals | Yes | Yes |
Even for low-TDS water, a UV purifier needs electricity. If you have long power cuts, look at a storage model or our non-electric picks.

How we score: the BachatPaisa score is our editorial rating out of 5. It’s based on published specs, warranty terms, service reach and value for money.

1. Aquaguard Sure Delight UV+UF 2X – Best overall
BachatPaisa score: 4.4/5

The free service plan covers installation, two cleaning visits and unlimited repairs in the first year. Aquaguard is clear that it’s for municipal water under 200 TDS only.
Key specs

A slim UV purifier with a mineral cartridge, touch controls and dispensing at up to 2 litres a minute. The tank is just 2 litres, so it suits a couple or a small family in a compact kitchen.
Like the others, it’s for municipal water under 200 TDS only.

Check these before you buy
- Measure TDS at your kitchen tap, not from the building’s bottled supply
- Re-test after the monsoon, when some cities mix in tanker or bore water
- Clean the overhead tank twice a year; it’s where most contamination comes from
- If your building mixes borewell water into the supply, buy an RO instead
Questions people ask us
Which water purifier is best for municipal water?
A UV + UF purifier if your TDS is under 200 ppm. Our pick is the Aquaguard Sure Delight UV+UF 2X.
Is RO necessary for municipal water?
Usually not. If your TDS is under 200 ppm, RO wastes water and removes minerals you don’t need removed. UV + UF handles the germs.
Can I use a UV purifier on borewell water?
No. UV doesn’t remove dissolved salts or hardness. Brands like Aquaguard say clearly that their UV models aren’t for borewell or tanker water.
What TDS is municipal water usually?
Often between 50 and 200 ppm in large cities, but it varies by area and season. Test your own tap.
Do UV purifiers need electricity?
Yes, for the UV lamp. In areas with long power cuts, consider a gravity purifier as a backup.
Bottom line
Test first. Under 200 TDS, buy the Aquaguard Sure Delight UV+UF 2X and save both water and money on filters. For a big household, the KENT Ultra Storage. Over 200 TDS, go to our borewell or hard water guide.
