Clean, safe drinking water is non-negotiable, and the right water filter is what stands between your family and the contaminants hiding in ordinary tap or borewell water. Choosing the best water filter in India means navigating RO, UV, UF and gravity technologies, dozens of brands, and a wide range of capacities and features, which can quickly feel overwhelming.
To make it simple, we researched the most popular and best-rated water filters across trusted Indian brands and judged each on purification technology, suitability for your water type, capacity, maintenance and real customer ratings. Whether your home gets hard borewell water that needs RO or low-TDS municipal water where UV or UF is enough, there is a well-reviewed water filter here to match your needs.
Every recommendation below is a water filter you can order today, chosen to combine effective, safe purification with genuine everyday value. Below you will find our top picks, a clear comparison table and a complete buying guide so you can choose the best water filter for your home with total confidence.
How to Choose the Best Water Filter in India
The single most important factor when choosing a water filter is your water source. Hard or borewell water with a high TDS level needs an RO (reverse osmosis) filter to remove dissolved salts, while low-TDS municipal water is safely handled by a UV or UF filter that kills germs without stripping minerals. Testing your water TDS first ensures you buy the right technology rather than overspending or under-protecting your family.
After technology, weigh storage capacity for your family size, the purification stages and mineral retention, ongoing filter and maintenance costs, and the brand service network in your city. A good water filter balances effective purification with easy, affordable upkeep, so you get safe water for years without hassle.

It is purpose-built for municipal and low-TDS supplies, using UV light to kill bacteria and viruses while retaining the natural minerals already present in soft water, so you get safe, good-tasting water without RO’s mineral loss or water wastage.
Because UV purification does not use a membrane or reject water, it is economical to run and wastes nothing, which suits homes on treated corporation water. Aquaguard’s reliability and wide service network give real peace of mind on maintenance. With a 4.2-star rating, the Sure Champ is our top UV pick for households whose water is low in dissolved solids but needs germ protection — an efficient, trusted, no-waste purifier that does exactly what UV should.

2. KENT Ultra Storage UV+UF Water Purifier — Best with Storage
The KENT Ultra Storage is the best water filter with a storage tank, combining UV and UF (ultrafiltration) to handle municipal water even during power cuts. UF adds a physical membrane that traps cysts and larger impurities alongside UV’s germ-killing, and the built-in storage tank means you always have purified water ready, even when the electricity is off — a genuine advantage over tankless UV units.
KENT is a well-known Indian water purifier brand, and this model suits homes on low-TDS supplies that want the reassurance of both UV disinfection and UF filtration without RO’s water wastage. The storage tank is especially useful in areas with unreliable power. With a 4.0-star rating, the KENT Ultra Storage is the pick for municipal-water households that want germ-free water on tap at all times, backed by a trusted purifier brand.

3. Havells Aquas Lite UV+UF Water Purifier — Best Value
The Havells Aquas Lite is the best value water filter, pairing UV and UF purification in a compact, energy-efficient unit from a trusted Indian electrical brand. It targets municipal and low-TDS water, using UV to kill germs and UF to trap cysts and sediment, delivering safe water without the running cost and wastage of an RO system.
Havells brings solid build quality and a clean, compact design that fits smaller kitchens, and its 4-star efficiency keeps power use low. It is an affordable way to get dual UV+UF protection for homes that do not need RO. Being honest, its rating sits a little lower than our top picks, so it is best chosen for value and compactness rather than premium features. With a 3.9-star rating, the Aquas Lite is the pick for budget-conscious municipal-water homes wanting reliable UV+UF purification.

4. Pureit Wave Plus RO+UV+Mineral Water Purifier — Best if TDS is Higher
The Pureit Wave Plus is the best pick if your water needs UV protection but also has higher TDS, combining RO, UV and mineral enrichment in one unit. Pure UV works only on low-TDS water; if your supply is hard or borewell-fed, you need RO to reduce dissolved solids first, and this Pureit adds UV on top to kill any remaining germs — the safest combination for uncertain or hard water.
From Pureit (a Hindustan Unilever brand), it also re-adds essential minerals after purification for better taste and health, and includes a storage tank for use during power cuts. With an excellent 4.4-star rating — the highest here — it is the reassuring all-rounder for homes unsure of their water type. If your water is not clearly low-TDS, this RO+UV Pureit is the safer choice over a pure UV unit, giving both TDS control and UV germ protection.

It combines RO to bring down dissolved solids with UV to kill bacteria and viruses, covering both mixed municipal supplies and harder water in a single trusted unit.
Aquaguard backs it with a free-service offer and its extensive nationwide service network, taking the worry out of maintenance — a big plus for a water purifier you rely on daily.

6. AQUA D PURE UV+UF 12L Water Purifier — Best Large Storage Budget
The AQUA D PURE UV+UF is the best large-storage budget water filter, offering a generous 12-litre tank and 7-stage UV+UF purification at an affordable price. The big storage suits larger families or homes with erratic power and water supply, keeping plenty of germ-free water ready without RO wastage — useful for low-TDS municipal supplies.
The multi-stage UV+UF process kills bacteria and traps sediment and cysts, and the large capacity means fewer refills through a busy day. Being honest, this budget model carries a lower 3.6-star rating than our top picks, so it is best chosen for its capacity and price rather than premium build or service. With that caveat, the AQUA D PURE is the pick for big municipal-water households wanting maximum stored purified water on a tight budget.

How to Choose the Best Water Filter
Know your water TDS first
This is the single most important step. water filters work only on low-TDS water (roughly under 300 ppm), typically treated municipal or tank supply. If your water is hard or borewell-fed with high TDS, you need an RO purifier instead — UV alone will not reduce dissolved solids.
UV vs UV+UF
Pure UV kills germs but does not remove suspended particles. UV+UF adds ultrafiltration to trap cysts, sediment and larger impurities, and importantly can work without electricity. For municipal water that may carry particles, UV+UF is the safer, more complete choice.
Storage tank
A built-in storage tank means purified water is ready even during power cuts, which is a real advantage in many Indian homes. Tankless UV units purify on demand but stop working when the power is off, so pick storage if your supply is unreliable.
Brand and service
A water purifier needs regular filter and lamp changes, so choose a trusted brand like Aquaguard, KENT, Pureit or Havells with a wide service network. Reliable after-sales support keeps your purifier running safely for years.
When to choose RO+UV instead
If you are unsure of your water quality, or it varies, an RO+UV unit is the safer bet — RO reduces TDS and UV kills germs. Pure UV is only ideal when you are confident your water is genuinely low in dissolved solids.
Frequently Asked Questions
What is a water filter and how does it work?
A water filter uses ultraviolet light to kill bacteria, viruses and other germs in water without removing dissolved minerals. It is ideal for low-TDS municipal or tank water that is largely safe but may be microbiologically contaminated, giving germ-free water without RO’s mineral loss or wastage.
Is a water filter good for all water?
No. water filters work only on low-TDS water (roughly under 300 ppm), such as treated municipal supply. They do not reduce dissolved solids, so for hard or borewell water with high TDS you need an RO purifier instead. Always check your water TDS first.
What is the difference between UV and RO water purifiers?
UV kills germs using ultraviolet light but keeps dissolved solids and minerals, suiting low-TDS water. RO forces water through a membrane to remove dissolved solids, salts and heavy metals, suiting hard or high-TDS water. Many purifiers combine RO+UV for complete protection.
Does a water filter waste water?
No, and that is a key advantage. Unlike RO, UV purification does not reject any water, so nothing is wasted and running costs are low. This makes UV economical for homes on already-soft municipal water that only needs germ protection.
Do water filters need electricity?
Pure water filters need electricity to power the UV lamp and stop working during power cuts unless they have a storage tank. UV+UF models can filter water through the UF membrane even without power, making them more reliable where the electricity supply is erratic.

Conclusion
The best water filter depends on your water. For low-TDS municipal water, the Aquaguard Sure Champ UV is our top pick — germ-free water with no wastage. Want a storage tank? Choose the KENT Ultra Storage UV+UF, and for value the Havells Aquas Lite. But if your water is hard or high-TDS, go for an RO+UV unit like the Pureit Wave Plus instead. Always check your water TDS first — it decides whether UV alone is enough.
