Water Purifier Price in India: What Each Budget Actually Buys
Published 2 November 2026
Water purifier prices in India run from a few thousand rupees for basic UV or UF units to well above ₹30,000 for premium RO systems. The price mostly buys more stages, a membrane rated for higher input TDS, monitoring, a better form factor and more dependable service, not necessarily safer water. The right tier is set by your water, so test it before you set a budget.
Water Purifier Price Tiers at a Glance
The table below describes what each tier typically includes in the Indian market. It is a general guide drawn from how purifiers are commonly specified, not measured data, and individual models vary in both directions.
| Tier | Typical technology and stages | Monitoring | Form factor and tank | Service and warranty |
|---|---|---|---|---|
| Under ₹10,000 | UV, UF or a basic RO with a few stages | Usually none, or a simple indicator light | Wall-mounted, plastic tank | Often third-party service; shorter or narrower warranty |
| ₹10,000 to ₹20,000 | RO with UV or UF, sometimes a mineral or TDS-adjust stage | Sometimes a filter-change reminder | Wall-mounted or countertop | Brand service common; read what the warranty excludes |
| ₹20,000 to ₹30,000 | Multi-stage RO with UV, mineral control that does not bypass purification | Displayed input and output TDS, filter health, alerts, sometimes an app | Wall-mounted, under sink or hot water options; some steel tanks | Installation by the brand’s own team more common |
| Above ₹30,000 | Larger or heavier-duty systems, hot and cold options, premium finishes | App-based monitoring is common | Freestanding, under sink, designer units | Varies; price alone does not guarantee better service |
Price is not purity. A well-chosen UV purifier on clean, low-TDS municipal water can serve you better than an expensive RO that strips water you did not need to treat. Pay for what your water needs first, then for convenience.
What Changes as the Price Rises
- Stages. More stages are not automatically better. Ask what each stage does: sediment, carbon, RO, UV or UF, and any mineral stage.
- TDS rating. The membrane’s rated input TDS tells you what water it is designed for. Many home RO purifiers are rated for input up to about 2000 TDS. If your water is near that, the rating matters more than any other feature.
- Monitoring. Cheaper units leave you guessing when filters are due. Mid and upper tiers show input and output TDS and filter health, so you change parts on condition.
- Tank and form factor. Under sink, hot water and stainless steel tank designs mostly appear above ₹20,000.
- Service and warranty. Who installs, who services, and what the warranty excludes often decide your experience more than the hardware.
Purchase Price vs the 5-Year Cost
The sticker price is only the first payment. Over five years you will also pay for sediment and carbon filters, at least one membrane change on most RO units, UV parts, service visits and, if you take one, an annual maintenance plan. On some budget purifiers these running costs add up to more than the purchase price, so a cheaper unit with frequent or expensive filter changes can cost more overall.
Before you buy, ask for the price of a full filter set, what triggers a replacement (a calendar date or the filter’s actual condition) and what a service visit costs after the warranty. Our guides to the true cost of owning a water purifier and the 5-year water purifier maintenance cost show how to add it all up.
Hidden Costs to Ask About
- Installation. Some sellers charge for installation, extra pipe, a wall bracket or a counter hole for an under sink faucet. Ask if installation is free and who does it.
- AMC. An annual maintenance contract can be useful, but check whether it covers the membrane and parts or only labour.
- External pre-filters. Borewell and tanker water with heavy sediment often needs an extra pre-filter outside the purifier, with its own cartridges to replace.
- Booster pump. RO needs a minimum water pressure. Homes fed by a low overhead tank, or on upper floors of a weak supply, may need a booster pump, which is sometimes sold separately.
- Electricity and reject water. RO and UV need power, and RO sends a share of water to the drain. Neither is large, but both are ongoing.
Before you pick a tier, check typical TDS for your pincode, then confirm it with a meter at your own tap. It decides whether you need RO at all.
Check Your Water →Rent or Buy?
Rental services charge a monthly fee that usually includes filters and service, with little or nothing upfront. That suits people who move every year or two, or who want no upfront spend. Over a longer stay, the monthly fees add up, and you never own the unit. Buying costs more on day one but is usually cheaper over several years if you maintain it properly. Our comparison of water purifier rental vs buying works through the numbers.
Match the Tier to Your Water
- Low TDS municipal water (under about 200): microbial safety is the main concern. UV or UF is often enough, and the lowest tier may serve you well.
- Moderate TDS (about 200 to 500): RO is optional and depends on taste and what a test shows. Mineral control helps if RO water tastes flat.
- High TDS (above 500), borewell or tanker water: you need RO rated for your input, plus UV or UF. This is where mid and upper tiers earn their price.
BIS IS 10500 sets 500 mg/L as the acceptable TDS limit and 2000 mg/L as permissible only where no alternative source exists. A lab test for hardness, fluoride, nitrate and iron is worth the small cost if your supply is borewell water.
Boon Prices at the Time of Writing
Boon’s home purifiers sit in the ₹20,000 to ₹30,000 tier. All three are RO purifiers rated for input up to 2000 TDS, with WaterAI monitoring, free installation by Boon’s own team, a 2-year warranty and a 10-day money-back guarantee.
| Purifier | Price (at the time of writing) | What it is |
|---|---|---|
| Boon Homie | ₹21,900 | Wall-mounted 5-stage UltraOsmosis RO with in-line LED UV, 20 litres per hour into an 8-litre tank, three Water Profiles |
| Boon Tap | From ₹23,500 | Under sink 8-stage UltraOsmosis RO with an 8-litre tank and a dedicated faucet on the counter |
| Boon Homie Pro | ₹25,900 | Everything Homie does plus instant hot water and per-person Track logging; 4-litre stainless steel tank; no cold water |
Where Boon is not the answer: if your TDS is low and you only need microbial safety, an RO at this price is more than you need. Boon Tap UF, which has no RO, exists for low-TDS supplies. If you are weighing these three against other purifiers in the same range, our guide to the best water purifier under ₹25,000 sets out what this tier should give you and how to check it.
Frequently Asked Questions
What is the price of a good water purifier in India?
A good water purifier can cost anywhere from under ₹10,000 to above ₹30,000, depending on what your water needs. For low TDS municipal water, a basic UV or UF unit may be enough. For high TDS borewell or tanker water, expect to pay more for an RO rated for your input TDS. Add five years of filters and service before deciding.
Why is an RO water purifier more expensive than UV?
An RO purifier needs a membrane, a pump to push water through it, a drain line and usually UV or UF after it, so there is more hardware. It also has more parts to replace over time, especially the membrane. UV and UF are simpler and cheaper, but they do not reduce dissolved salts, so they suit only low TDS water.
Is a costly water purifier always better?
No. A higher price usually buys more stages, monitoring, a better form factor or more dependable service, not necessarily safer water. A purifier must match your water. An expensive RO on low TDS water can be overkill, while a cheap UV on high TDS borewell water does not do the job. Test your water first, then compare.
What hidden costs come with a water purifier?
Common hidden costs are installation charges and fittings, an annual maintenance contract that may exclude the membrane, external pre-filters for sediment-heavy water, a booster pump where water pressure is low, and replacement filters and service visits after the warranty. Ask about each one before you pay so the five-year cost does not surprise you.
Is it cheaper to rent or buy a water purifier?
Renting costs little upfront and usually includes filters and service, which suits people who move often. Over several years the monthly fees add up and you never own the unit. Buying costs more on day one but is usually cheaper over a longer stay, as long as you maintain the purifier on schedule.
How much do Boon water purifiers cost?
