Most buyers shopping for the best water purifier under ₹10,000 start with brand loyalty: KENT or Aquaguard, Livpure or Faber. That instinct costs them money and, sometimes, safety. Here is the reality that spec sheets make clear but most listicles bury: under ₹10,000, RO and UV purifiers sit at nearly the same price point, yet they do fundamentally different jobs. An RO unit strips dissolved solids (TDS) from borewell or tanker water. A UV unit kills microbes in already-low-TDS municipal supply but leaves TDS untouched. A gravity UF filter needs no electricity and no plumbing but also cannot reduce TDS at all.
Buying RO for municipal water wastes water and filter money on a problem you do not have. Buying UV for borewell water is unsafe, because UV does not cut TDS. That mismatch is the single most common mistake at this budget, and it is entirely avoidable if you match the technology to your input water first.
This page exists to publish the decision logic that nobody else at this price point lays out. We have built a technology-fit table that cross-references each of the six sub-₹10,000 models by purification type, the water it is designed for, storage, running cost where published, and water-recovery behavior. We have not tested these units in a lab. We have read every manufacturer spec sheet and mined the owner-review data, and we present what the columns actually say.
Quick Verdicts
Best overall under ₹10,000 (for high-TDS / borewell / tanker water): Livpure GLO PRO++: RO+UV+UF, 7 L storage, the most complete purification stack under budget.
Best budget RO for high-TDS water: Aqua D Pure 4-in-1 Copper: RO with TDS adjuster and copper, 12 L storage, the cheapest genuine RO in the field.
Best UV-only for municipal low-TDS water: KENT Smart Plus UV: UV+UF+Alkaline+Copper, the highest-rated UV unit in this cohort.
Best non-electric / gravity purifier: KENT Gold Optima: gravity UF, no electricity, no installation, the cheapest option that is genuinely worth buying for the right water type.

This is the table nobody else publishes. Read your row first.
| Model | Purification Type | Designed For | Max Input TDS | Storage | Water Wasted | Filter Cost / Yr | Price Band (July 2026) | Rating |
|---|---|---|---|---|---|---|---|---|
| Livpure GLO PRO++ |
RO + UV + UF | Borewell / tanker / municipal (high or variable TDS) | 2000 ppm (Amazon field) | 7 L | Not published | Not published | ₹8,900–₹9,500, as of July 2026 | 4.1 stars across 14,866 ratings, July 2026 |
 Aqua D Pure 4-in-1 Copper |
RO + UV + UF + TDS adjuster + Copper | All water types (mfr claim) | Not published numerically | 12 L | Not published | Not published (service kit ₹1,500 sale; interval unknown) | ₹5,000–₹5,300, as of July 2026 | 4.2 stars across 12,663 ratings, July 2026 |
 Faber CUV 8000 |
UV + UF + Copper (NOT RO) | Low-TDS municipal / tap water | 200 ppm | 7 L | None (no RO reject stream) | Not published | ₹6,500–₹6,800, as of July 2026 | 4.2 stars across 613 ratings, July 2026 |
 Aquaguard Sure Mist |
UV + Mineral Charge (NOT RO) | Low-TDS municipal water only | Up to 200 mg/L | No storage tank (mfr spec) | None (no RO reject stream) | Not published | ₹7,400–₹7,500, as of July 2026 | 4.2 stars across 452 ratings, July 2026 |
 KENT Smart Plus UV |
UV + UF + Alkaline + Copper (NOT RO) | Low-TDS municipal / tap water only | Not published numerically | Storage-less (60 L is flow rate, not tank) | None (no RO reject stream) | Not published | ₹7,900–₹8,000, as of July 2026 | 4.4 stars across 183 ratings, July 2026 |
 KENT Gold Optima |
Gravity UF (non-electric) | Low-TDS municipal / tap water only | UF does not reduce TDS (mfr) | 10 L total (5 L raw + 5 L purified) | None (no reject stream) | Not published | ₹2,100–₹2,200, as of July 2026 | 3.6 stars across 15,855 ratings, July 2026 |
The insight this table exists to deliver: RO units (Livpure, Aqua D Pure) are for water with high or variable TDS: borewell, tanker, or hard municipal supply. UV and gravity units (Faber, Aquaguard Mist, KENT Smart Plus, KENT Gold Optima) are for already-soft, low-TDS municipal water. UV kills microbes. UF filters out particulates and bacteria. Neither reduces TDS. If your input water has TDS above roughly 200 ppm, a UV-only purifier will give you microbe-free water that still carries the same dissolved-salt load. That is not a failure of the product. It is a mismatch between technology and water source.
Running cost at this budget: When the sticker price is ₹5,000 to ₹9,000, the consumable cost over three years often matters more than the purchase price. Most manufacturers in this cohort do not publish filter replacement costs or intervals. Aqua D Pure sells a complete RO service kit with copper cartridge at ₹1,500 sale price, but the replacement interval is not published, so a per-year cost cannot be computed. We mark every cell “not published” honestly where the manufacturer has not disclosed it. This is itself useful information: brands that do not publish running costs make it harder for you to compare total ownership cost.

Decision Gate: What Is Your Water?
Before you look at a single brand, answer one question: what comes out of your tap?
Step 1: Check your TDS. Get your municipal water quality report from your local utility, or buy a ₹150 TDS meter and test the water you actually drink. The number tells you which technology you need.
Step 2: Match technology to TDS.
-
High or variable TDS (borewell, tanker, hard municipal): You need RO. RO is the only technology in this price band that reduces dissolved solids. Among the six models, that means the Livpure GLO PRO++ or the Aqua D Pure 4-in-1 Copper. See our dedicated RO water purifier guide if you have decided on RO specifically and want the wider field.
-
Low-TDS municipal water (already soft, TDS within safe limits): You need UV or UV+UF to kill microbes, not RO. RO would strip minerals you want to keep and waste water you do not need to filter. The Faber CUV 8000, Aquaguard Sure Mist, and KENT Smart Plus UV all fit here.
-
Low-TDS municipal water, no electricity or no plumbing: A gravity UF unit like the KENT Gold Optima works without power or installation. It filters bacteria and particulates but does not reduce TDS and does not kill viruses the way UV does.
Step 3: Pick the model in your technology band. The table above and the per-model sections below do that.
How We Research
We do not run lab tests. Our process:
-
Spec extraction: We pull every published specification from the manufacturer’s official product page and the Amazon listing, then reconcile discrepancies. When the manufacturer and Amazon disagree, the manufacturer value wins (per our source-fidelity rule). We flag every discrepancy transparently in the notes.
-
Review mining: We cite the aggregate rating and total review count from the Amazon listing as of the retrieval date. We do not hand-pick individual reviews or claim to have read a specific percentage of them.
-
Running-cost honesty: Where a manufacturer does not publish filter replacement intervals or costs, we say “not published.” We do not estimate or infer.
-
Technology-fit framing: We cross-reference purification type against the manufacturer’s stated input-water suitability. If a UV unit says “municipal water only,” we report that, because it is the single most important buying criterion at this budget.
Full methodology: how we research.
Livpure GLO PRO++ (RO + UV + UF)
Spec summary: 7-stage RO+UV+UF purification (sediment filter, pre-activated carbon, anti-scalant, RO membrane, UV disinfection, ultrafiltration, silver-impregnated post carbon). 7 L storage. Amazon lists a max input TDS of 2000 ppm; the manufacturer states suitability for borewell, tanker, and municipal water without publishing a numeric maximum. 1-year manufacturer warranty with free standard installation and free on-demand service under the Livpure Smart Service Plan.
Rating: 4.1 stars across 14,866 ratings, July 2026.
Price: ₹8,900–₹9,500, as of July 2026.
Who it is for: Households on borewell, tanker, or variable municipal supply where TDS is high or unpredictable. The RO+UV+UF stack is the most complete purification chain in the sub-₹10,000 field. If you do not know your TDS and want one unit that handles everything, this is the safest single choice under budget.
Who should NOT buy it: Households on soft, low-TDS municipal water where TDS is already within safe limits. RO will strip minerals and waste water unnecessarily. A UV unit at half the price would do the job.
Aqua D Pure 4-in-1 Copper (RO + UV + UF + TDS Adjuster + Copper)
Spec summary: 10-stage purification: RO+UV+UF with an inbuilt TDS adjuster and 4-in-1 copper technology. 12 L storage, the largest tank in this cohort. The manufacturer claims suitability for “all types of water supply” but does not publish a numeric max input TDS. Warranty is not published by either source. Installation is paid (up to ₹500 to the technician). The manufacturer sells a complete RO service kit with copper cartridge at ₹1,500 sale price (₹2,999 MRP), but the replacement interval is not published, so a per-year running cost cannot be computed.
Rating: 4.2 stars across 12,663 ratings, July 2026.
Price: ₹5,000–₹5,300, as of July 2026.
Who it is for: Buyers who need RO purification (high or variable TDS) and want the cheapest genuine RO unit in the field. The 12 L storage is a practical advantage for larger households. The inbuilt TDS adjuster lets you retain some minerals if your input TDS is not extremely high.
Who should NOT buy it: Households on low-TDS municipal water. This is an RO unit; you are paying for a membrane you do not need. Also, note that Aqua D Pure is a marketplace brand with a Wix storefront. Spec depth is limited compared to established brands like Livpure or KENT, and the paid installation (up to ₹500) is an extra cost the other brands in this list do not charge.
Faber CUV 8000 (UV + UF + Copper)
Spec summary: 7-stage UV+UF+Copper purification (NOT RO): 10-micron sediment, pre-carbon, 5-micron sediment, post-carbon, Copper Guard, 11W UV lamp, UF membrane. 7 L storage. Filtration limit of 200 ppm (both sources agree). No RO reject stream, so no water is wasted by design. 1-year comprehensive warranty. Installation and demo via Faber customer care (terms and charge not published).
Rating: 4.2 stars across 613 ratings, July 2026.
Price: ₹6,500–₹6,800, as of July 2026.
Who it is for: Households on low-TDS municipal supply (TDS at or below 200 ppm) who want UV+UF purification with copper dosing and a storage tank, without the water waste of RO. The 7 L storage makes it practical for daily kitchen use.
Who should NOT buy it: Anyone on borewell, tanker, or high-TDS water. This is a UV+UF unit. It does not reduce TDS. The Faber product page contains boilerplate RO-model text (2500 ppm / 93% TDS reduction) that does NOT apply to this UV model. Ignore it. The review count is also low (613), so the rating has less statistical weight than the Livpure or Aqua D Pure.
Aquaguard Sure Mist (UV + Mineral Charge)
Spec summary: UV e-boiling + Mineral Charge (UV+MC). 11W UV lamp, 60 LPH flow rate. No storage tank (manufacturer spec table wins over the Amazon field listing of 2 L; this is a storage-less online purifier). Input water: up to 200 mg/L, municipal water only, not borewell or tanker. No RO reject stream, so no water wasted. 1-year warranty with a Free Service Plan worth ₹2,000 (free installation, one maintenance visit, unlimited repair visits).
Rating: 4.2 stars across 452 ratings, July 2026.
Price: ₹7,400–₹7,500, as of July 2026.
Who it is for: Households with reliable municipal water supply (TDS at or below 200 mg/L) who want a no-storage, wall-mounted UV purifier from an established brand with a strong service plan. The Aquaguard service plan is the most generous free-service offering in this cohort.
Who should NOT buy it: Anyone who needs storage. This unit has no tank. Water is purified on demand. If your municipal supply is intermittent, you need a unit with storage. Also not suitable for borewell or tanker water, as UV does not reduce TDS.
KENT Smart Plus UV (UV + UF + Alkaline + Copper)
Spec summary: UV+UF+Alkaline+Copper purification (NOT RO). 60 L/hr purification rate. Alkaline cartridge raises pH to 8 to 9.5. Copper cartridge dosing at or below 2 mg/L (WHO limit). UV-fail alarm. Fully automatic. Storage-less online purifier (the Amazon field listing “60 Liters” is the flow rate, not a storage tank; the manufacturer publishes no storage capacity). Low-TDS municipal or tap water only; UV+UF does not reduce TDS. 1-year warranty.
Rating: 4.4 stars across 183 ratings, July 2026. The highest rating in this cohort, though the review count is low.
Price: ₹7,900–₹8,000, as of July 2026.
Who it is for: Households on low-TDS municipal water who want alkaline and copper enhancement alongside UV+UF microbe killing. The pH-boosting alkaline cartridge is a feature the other UV units in this list do not offer. The UV-fail alarm is a safety feature worth having.
Who should NOT buy it: Anyone on high-TDS water. Also, anyone who needs storage. This is a storage-less online unit. The low review count (183) means the 4.4-star rating should be treated with caution compared to the Livpure’s 14,866-review base.
KENT Gold Optima (Gravity UF, Non-Electric)
Spec summary: Gravity-fed UF with a 0.1-micron hollow-fibre membrane. Non-electric, chemical-free (no chlorine, bromine, or iodine). Retains all natural minerals. 10 L total storage (5 L unpurified top tank + 5 L purified bottom tank). No installation required (countertop gravity unit). 1-year warranty.
Rating: 3.6 stars across 15,855 ratings, July 2026. The lowest-rated unit in this cohort.
Price: ₹2,100–₹2,200, as of July 2026.
Who it is for: Households on low-TDS municipal or tap water who have no reliable electricity, no plumbing for an installed purifier, or need a secondary unit for a rental or a kitchen without a wall-mount point. At ₹2,100, it is the cheapest option in this field that provides genuine UF filtration. The non-electric, no-installation design is a real advantage for specific use cases.
Who should NOT buy it: Anyone on borewell, tanker, or high-TDS water. UF does not reduce TDS. The manufacturer explicitly states this, and the Amazon field listing claiming “2000 ppm” is misleading because UF passes TDS through. At 3.6 stars across 15,855 ratings, it is the lowest-rated unit in this cohort. Note the capability limit before buying: UF does not reduce TDS, so it is not a substitute for RO on hard or high-TDS water. This unit filters bacteria and particulates. It does not soften water.
Just Over Budget: Aquaguard Sure Delight NXT RO+UV+UF Aquasaver
If you can stretch by approximately ₹1,000, the Aquaguard Sure Delight NXT sits at ₹10,900–₹11,100, as of July 2026. It offers 9-stage RO+UV+UF with a Mineral Charge cartridge, 6 L storage (manufacturer spec wins over the Amazon 6.2 L field), input TDS up to 2000 mg/L, and Aquaguard’s “up to 60% water savings” Aquasaver claim. It carries 4.1 stars across 8,366 ratings, July 2026, with a Free Service Plan worth ₹2,000. It is not a pick on this page because it crosses the ₹10,000 line, but it is the natural next step up if you want RO+UV+UF with water-saving technology and a strong service plan.
How to Choose a Water Purifier Under ₹10,000
Step 1: Determine your water source
| Water Source | Typical TDS | Technology You Need | Models in This Field |
|---|---|---|---|
| Borewell / tanker | High or variable | RO | Livpure GLO PRO++, Aqua D Pure 4-in-1 Copper |
| Municipal, soft | Low (at or below ~200 ppm) | UV or UV+UF | Faber CUV 8000, Aquaguard Sure Mist, KENT Smart Plus UV |
| Municipal, soft, no electricity | Low | Gravity UF | KENT Gold Optima |
We do not publish specific city TDS numbers because they are not in our spec data. Check your local municipal water report or test with a TDS meter.
Step 2: Decide if you need storage
- Need storage (intermittent supply): Livpure GLO PRO++ (7 L), Aqua D Pure (12 L), Faber CUV 8000 (7 L), KENT Gold Optima (10 L total).
- No storage needed (reliable supply): Aquaguard Sure Mist, KENT Smart Plus UV. Both are storage-less online purifiers.
Step 3: Factor in running cost
At a ₹5,000 to ₹9,000 purchase price, filter replacement cost over three years can rival the sticker. Most manufacturers in this cohort do not publish per-year filter costs. Aqua D Pure sells a complete service kit at ₹1,500 sale price but does not publish the replacement interval. We mark everything else “not published” because that is the honest answer. When a brand does not disclose running costs, budget for annual filter replacement as an unknown.
Step 4: Check warranty and service
- Livpure: 1-year warranty, free standard installation, free on-demand service under warranty.
- Aqua D Pure: warranty not published, paid installation (up to ₹500).
- Faber CUV 8000: 1-year comprehensive warranty, installation via Faber customer care (terms not published).
- Aquaguard Sure Mist: 1-year warranty, Free Service Plan worth ₹2,000 (installation + maintenance + unlimited repairs).
- KENT Smart Plus UV: 1-year warranty, installation terms not published.
- KENT Gold Optima: 1-year warranty, no installation required.
FAQs
Which is the No. 1 water purifier?
There is no single “No. 1” across all water types. For high-TDS or borewell water under ₹10,000, the Livpure GLO PRO++ (RO+UV+UF, 4.1 stars across 14,866 ratings) offers the most complete purification stack. For low-TDS municipal water, the KENT Smart Plus UV (4.4 stars across 183 ratings) has the highest rating in this cohort. The right answer depends on your input water, not on a universal ranking.
What is the best water purifier for home use?
For most Indian homes with variable or unknown water quality, an RO+UV+UF unit like the Livpure GLO PRO++ covers the widest range of input water. If your municipal supply is reliably soft and low-TDS, a UV+UF unit like the Faber CUV 8000 or KENT Smart Plus UV is the better fit and avoids the water waste inherent to RO.
Which water purifier is best and cheap?
The KENT Gold Optima at ₹2,100–₹2,200, as of July 2026, is the cheapest water purifier in this field that provides genuine filtration (gravity UF, 0.1-micron membrane). However, it does not reduce TDS and carries the lowest rating in this cohort (3.6 stars across 15,855 ratings). The Aqua D Pure 4-in-1 Copper at ₹5,000–₹5,300 is the cheapest genuine RO unit.
What water purifier is best?
The best water purifier is the one matched to your water source. RO for high-TDS water. UV or UV+UF for low-TDS municipal water. Gravity UF for low-TDS water without electricity. Buying the wrong technology for your water is the most expensive mistake you can make, regardless of the sticker price.
Is KENT better or Aquaguard?
Both brands appear in this cohort. KENT offers the Smart Plus UV (4.4 stars across 183 ratings, UV+UF+Alkaline+Copper) and the Gold Optima (3.6 stars across 15,855 ratings, gravity UF). Aquaguard offers the Sure Mist (4.2 stars across 452 ratings, UV+MC). KENT’s Smart Plus UV has the higher rating but a much smaller review base. Aquaguard’s Sure Mist includes a more generous free service plan. Neither brand is universally “better.” The decision should be based on whether you need storage (KENT Smart Plus is storage-less; Aquaguard Mist is also storage-less), whether you want alkaline enhancement (KENT Smart Plus offers it; Aquaguard Mist does not), and the service plan terms in your area.
Conclusion
Under ₹10,000, the real choice is not brand. It is technology. Match the purification type to your water source first, then pick the model.
- High or variable TDS (borewell, tanker): Livpure GLO PRO++ for the most complete stack, or Aqua D Pure 4-in-1 Copper for the cheapest RO with the largest storage.
- Low-TDS municipal water: KENT Smart Plus UV for the highest-rated UV unit with alkaline+copper, or Faber CUV 8000 for UV+UF with storage at a lower price.
- No electricity, no plumbing: KENT Gold Optima: the cheapest option that genuinely filters, for the right water type only.
- If you can stretch to ₹11,000: Aquaguard Sure Delight NXT adds water-saving RO and a strong service plan.
