How to Choose Your Perfect Water Purifier
1. Check Your Water Source & TDS
Use a TDS meter. High TDS (>500ppm) from borewells needs RO. Low TDS municipal water may only need UV/UF.
2. Match Capacity to Family Size
For 1-3 people, 5-8L storage is fine. For 4-6 people, aim for 8-12L to handle daily needs and power cuts.
3. Budget for Maintenance
Check the annual cost of replacement filters (sediment, carbon, RO membrane, UV lamp). A cheaper unit can be more expensive long-term.
4. Verify Local Service
A great purifier is useless without timely service. Check brand service availability and reviews for your specific pin code before buying.
Purifier Types Explained
RO (Reverse Osmosis)
Essential for high TDS water (>500ppm) from borewells or tankers. Removes dissolved salts, heavy metals, and minerals.
Pros: Most thorough purification.
Cons: Wastes water, removes healthy minerals.
UV (Ultraviolet)
Deactivates bacteria, viruses, and microbes. Ideal for low-TDS municipal water that is biologically contaminated.
Pros: No water wastage, kills germs.
Cons: Doesn't remove dissolved solids.
UF (Ultra Filtration)
A membrane filter that removes larger particles and microbes. Works without electricity but is less effective than RO or UV alone.
Pros: No electricity needed, no waste.
Cons: Can't remove dissolved solids or tiny viruses.
*Most modern purifiers in India use a combination (RO+UV+UF) for comprehensive protection.
Capacity & Suitability for Indian Homes
| Family / Use Case | Low TDS (<300ppm) | Mixed Source (300-800ppm) | High TDS (>800ppm) |
|---|---|---|---|
| 1–3 people | UV+UF, 5-7L Tank | RO+UV, 6-8L Tank | RO+TDS Control, 8L+ Tank |
| 4–6 people | UV+UF, 7-8L Tank | RO+UV+TDS, 8-10L Tank | High-Flow RO, 10L+ Tank |
| Office / High Usage | — | High-Flow RO, 10L+ | Commercial Grade RO |
Rule of thumb: When in doubt, a RO+UV+TDS Control model offers the most flexibility for variable Indian water conditions.
1–3 People
- Low TDS: UV+UF, 5-7L Tank

Maintenance & Safety Guide
Quick Safety Tips
Stable Power: Connect to a dedicated socket. Avoid using long extension cords which can be a hazard.
Proper Placement: Ensure the unit is on a level surface or securely wall-mounted, away from direct sunlight.
Clean Handling: Wash hands before dispensing water and keep the tap area clean to prevent re-contamination.
Maintenance Schedule
Quarterly: Change sediment & carbon pre-filters, especially with hard or visibly dirty water.
Annually: Replace UV lamp (if present) as its intensity decreases over time.
Every 1-2 Years: Replace the RO membrane. Check output TDS to know when it's time.
Common Mistakes to Avoid
- ✔ Buying RO for Low TDS Water: If your input TDS is below 300, a full RO system is overkill. It wastes water and strips essential minerals. A UV+UF model is often better.
The Fix:
- Buy a TDS meter for ₹200.
- Test your tap water.
- If TDS < 300, consider UV/UF purifiers.
- ✔ Ignoring Filter & AMC Costs: The initial price is only part of the story. Annual filter changes and service contracts (AMC) can cost ₹2,000 - ₹5,000 per year.
The Fix:
- Ask for the price list of all consumable filters.
- Calculate the 3-year total cost of ownership.
- Compare this total cost, not just the purchase price.
- ✔ Overlooking Local Service: A top-tier brand is useless if their service technician in your area is unresponsive or poorly trained.
The Fix:
- Check brand service center locations online.
- Read local Google reviews for the service center.
- Ask neighbors about their experience with different brands.
Colours & Materials
Material Breakdown
Food-Grade ABS Plastic: The industry standard for the body and tank. It's durable, non-toxic, and easy to clean.
Transparent/Semi-Transparent Tanks: Made from materials like SAN, allowing you to monitor water levels visually.
Metal Accents: Premium models use stainless steel or copper elements for taps and internal components for better hygiene and aesthetics.
Colour Guidance
White and off-white are common and fit most kitchens, but can show stains over time. Black or grey models hide smudges better and offer a modern look. Choose a finish that complements your kitchen's color scheme and is easy to wipe clean.
Elder-Friendly & Accessible Solutions
Accessibility Checklist
- ✔ Clear, bright LED indicators for "Power On," "Purifying," and "Tank Full."
- ✔ Audible alerts for errors or when the tank is full are helpful.
- ✔ A simple, easy-to-press dispense button or lever that doesn't require much force.
- ✔ Avoid complex digital menus; simple function lights are better.
- ✔ Auto-fill and auto-shutoff features to reduce manual intervention.
Small Details for Architects & Designers
Plumbing Points
Provide a dedicated inlet point and a drain point for RO wastewater, especially for under-counter models.
Electrical Socket
A dedicated 6A socket with proper earthing is crucial. Place it close to the unit to avoid visible, trailing wires.
Service Access
Ensure there is enough clearance around the unit for a technician to easily open it and replace filters.
Ventilation
Purifiers generate some heat. Avoid boxing them into tight, unventilated cabinets to prevent overheating.
Designer’s Perspective: Expert Insights
“The biggest mistake is choosing style over substance. An under-counter unit looks fantastic, but if the plumbing isn't planned perfectly, it becomes a maintenance nightmare. Function must lead form.”
- Sourabh Jain | Design Educator
Key Design Considerations:
Hide the Drain
Route the RO wastewater pipe directly into the sink's P-trap.
TDS Control Matters
Advise clients to get a TDS controller for better tasting, healthier water.
Tank Hygiene
Models with in-tank UV are superior for preventing re-contamination.
Light It Well
Use under-cabinet lighting to illuminate the purifier and dispensing area.

Water Purifier Buying Guide 2025: Don't Buy Until You See This!
Frequently Asked Questions
Do I always need RO?
Only if your input water has high TDS (>500-600 ppm) or heavy metals. If water source is municipal with low-moderate TDS but microbial concerns, UV/UF may be enough.
Designer Verdict: Test your TDS before you buy.
What’s an acceptable TDS level for drinking water?
For most people, 100-300 ppm gives good taste. Below that may taste flat; above 600 creates hardness/mineral issues or an unpleasant taste.
Designer Verdict: Aim for 150ppm with a TDS controller.
How much water does an RO purifier waste?
Typically, for every litre of pure water, 2-3 litres are wasted. Models with high recovery technology can reduce this. You can collect and use the wastewater for cleaning or gardening.
Designer Verdict: Plan to reuse the wastewater.
How often do I need to change the filters?
Pre-filters (sediment, carbon) last 6-12 months. The RO membrane typically lasts 1.5-2 years. The UV lamp needs replacement annually. This depends heavily on your water quality and usage.
Designer Verdict: Follow the brand's schedule and budget for it.
Are mineral/alkaline/copper features necessary?
They help restore trace minerals and improve the taste of water after RO purification, which can taste flat. While not strictly necessary for safety, they are a good-to-have feature for health and taste.
Designer Verdict: Worth it if you dislike the taste of plain RO water.
Is an under-counter purifier better?
It's better for aesthetics as it frees up counter space and looks clean. However, it requires dedicated plumbing and can be harder to service. It's a choice of looks versus convenience.
Designer Verdict: Great for new modular kitchens, less so for retrofits.

Conclusion
If you want maximum value for lower cost, go with the Aquaguard Sure Delight or AQUA D PURE 4-in-1 Copper RO—they balance good purification, brand support, and manageable maintenance. If your kitchen is modern and you care about design and lower long-term effort, the Native M1 RO or Kent Sterling Plus Under-Counter are excellent. For heavy usage with high TDS water, the Kent Grand RO gives you robust performance and TDS control. Always double-check your local water quality, plan the plumbing, and factor in filter and service costs over the years. That makes more difference than a few extra features.
