Water Purifier Buying Guide
Importance of Checking TDS
Check TDS
of tap water before deciding on a water purifier.
RO purifiers can reduce TDS by over 90%, but excessive use can decrease TDS to less than 50.
Use a
TDS meter
to check TDS levels.
Choosing the Right Purifier Based on TDS
TDS < 200
: Use a
UV/UF water purifier
.
TDS 200-500
: Consider a
Nano or RO purifier
with TDS adjustment.
TDS > 500
: Use an
RO water purifier
(no need for TDS adjustment).
Water containing
arsenic or lead
: Use a
Nano or RO purifier
regardless of TDS.
Common Objections Addressed
TDS < 500
: Necessary to stay within appliance limits; RO may still be needed.
Low TDS levels
: Can mix a small amount of UF purified water to maintain TDS levels ideal for drinking (50-150 ppm).
Key Features to Consider
Filter Maintenance Costs
Urban Company offers a 2-year warranty on filters.
Check replacement frequency and costs.
Service Network
Kent and Aquaguard have the best networks.
Service depends on area; ask for demonstrations if required.
Pre-filtration
Pre-filters and sediment filters help extend the life of the RO membrane.
Important for areas with high sediment levels in water.
Filter Options
UF Filters
: Used for removing viruses and bacteria.
Carbon Filters
: Removes odors and improves water taste.
Additional Features
Mineralizer & Alkaline modules
: Optional.
Copper infusion
: May alter water taste.
Tank Capacity
: Ranges from 5 to 10 liters; important during power cuts.
Stainless Steel Tanks
: Available in some Aquaguard and Havells models.
Hot Water Dispensing
: Only in some models like AO Smith Z1.
Electricity-Dependent Dispensing
: Relevant for areas with frequent power cuts.
Touch-based dispensing models not recommended without power backup.
TDS Level Display
: Available in Urban Company models.
Price Range
Ranges from ₹8000 to ₹20000 depending on advanced features.
Recommended Models

Considerations for UV/UF Purifiers
Ideal for TDS < 200 ppm
Pre-filters & Sediment Filters Needed
Removes large particles and extends filter life.
Not always included in Aquaguard and Kent models; to be purchased separately.
Warranty & Maintenance
Typically 1-year; some offer 5-year UV lamp warranty.
Filter replacement costs range from ₹1500 to ₹2000.
Tank Size & Material
Ranges from 0 (instant purifiers) to 10 liters.
Stainless steel tanks available in specific models like Aquaguard Marvel.
Electricity Dependency
Some models dispense without electricity.
Hot Water Dispensing
AO Smith Z1 provides hot water (only UV purifier).
Recommended UV Purifiers (Budget < ₹8000)
Lifepure Glitz UV
7-liter tank, suitable for small-medium families.
Faber XV8
Includes essential filtration, decent service in Tier 1 and 2 cities.
H PURE Classic G2
Includes 5-year UV lamp warranty.
Provides SS tank and optional TDS adjuster.
Benefits of Nano Water Purifiers
Ideal for TDS 200-500 ppm.
Less water wastage compared to RO purifiers (0.5-1.5 liters per liter purified).
Effective in removing heavy metals like lead and arsenic.
Recommended Nano Water Purifiers
Pure Pro PS
Supports TDS up to 1200 ppm; includes UV, UF, and carbon filters.
