Why Buy a Water Purifier Under ₹20,000?
A ₹20,000 budget gives you access to more advanced water purification systems than many entry-level models.
Depending on the model, you may get:
- RO purification
- UV purification
- UF filtration
- TDS control
- Mineraliser
- Copper enrichment
- Alkaline filtration
- Larger storage tanks
- Multiple purification stages
- Better filter-life management
- Smart monitoring features
However, more features do not automatically mean that a purifier is better for every home.
The most important factor is whether the purification technology matches your water source.
Do You Need RO?
RO is particularly useful when the incoming water has high dissolved solids or contains contaminants that require membrane-based purification.
It is commonly considered for:
- Borewell water
- Tanker water
- High-TDS water
- Mixed water sources
For relatively low-TDS municipal water, RO may not always be necessary.
Before buying, test your water and choose the purification technology accordingly.
RO vs UV vs UF
RO
Reverse Osmosis uses a semi-permeable membrane to reduce dissolved substances and other contaminants from water.
RO is generally more relevant for higher-TDS water sources.
UV
Ultraviolet purification uses UV light to inactivate microorganisms.
UV does not remove dissolved salts from water.
UF
Ultrafiltration uses a membrane to remove suspended particles and certain microorganisms.
UF does not work like RO for reducing dissolved salts.
Best Combination
Some water purifiers combine:
RO + UV + UF
This provides multiple purification stages and can be useful for households dealing with different types of water impurities.
However, you should still select a purifier based on your actual water quality rather than simply choosing the purifier with the highest number of stages.
Important Features to Check Before Buying
1. Water Source
First identify where your drinking water comes from.
Common sources include:
- Municipal supply
- Borewell
- Tanker
- Mixed supply
- Open or private water sources
Your water source can help determine whether RO is necessary.
2. TDS Level
TDS means Total Dissolved Solids.
A TDS test can give you useful information about dissolved substances in your incoming water.
Do not choose a purifier only because its specifications mention a particular TDS number. Check the manufacturer’s recommended operating range for the exact model.
3. Storage Capacity
Storage capacity determines how much purified water can be stored for later use.
For example:
- 6L–7L: Suitable for smaller households
- 8L: Good all-round capacity
- 9L–10L: Useful for larger families or higher daily consumption
Actual usable capacity can vary by design.
4. Filter Replacement Cost
The purchase price is not the complete cost of owning a water purifier.
Also consider:
- Filter replacement
- RO membrane replacement
- UV lamp or module
- Service visits
- AMC
- Installation
- Maintenance
A purifier that is cheaper initially can become expensive if replacement filters and servicing cost more.
5. Water Wastage
RO purification can produce reject water.
When comparing RO models, check the manufacturer’s stated recovery rate or water efficiency.
You can also collect suitable reject water for non-drinking uses such as cleaning floors or washing vehicles, provided it is appropriate for that purpose.
6. Warranty
Check:
- Comprehensive warranty
- RO membrane warranty
- Electrical-component warranty
- Installation coverage
- Service availability
Warranty terms can vary significantly between brands and models.
Who Should Buy a Water Purifier Under ₹20,000?
This price range can be suitable for:
- Families looking for a feature-rich purifier
- Homes using borewell water
- Homes using tanker water
- Households with higher-TDS water
- Buyers wanting RO + UV purification
- Buyers wanting mineral or alkaline features
- People who want larger storage capacity
- Buyers looking for smart purification features
Who Should Not Buy an RO Purifier?
RO may not be necessary for every household.
If your incoming water is already suitable and has relatively low dissolved solids, an RO system may provide little additional benefit compared with a suitable non-RO purification method.
The correct choice depends on your water quality.

How to Choose the Best Water Purifier Under ₹20,000
Buying a water purifier should start with your water quality rather than the number of features.
1. Test Your Water First
Before purchasing an RO purifier, check the TDS and general quality of your incoming water.
Your water may come from:
- Municipal supply
- Borewell
- Tanker
- Mixed sources
The correct purification technology depends on the actual water quality.
2. Choose RO Only When You Need It
RO is useful for reducing dissolved solids and is commonly considered for higher-TDS water.
If your water has relatively low TDS and does not require RO treatment, a UV/UF-based purifier may be more appropriate.
Don’t pay for RO simply because it sounds more advanced.
3. Compare Storage Capacity
For a small family, 6–7 litres can be sufficient.
For a medium or larger family, 8–10 litres can provide more convenience.
Consider your daily drinking-water requirement before choosing the tank size.
4. Check Water Recovery
RO purifiers can produce reject water.
Look for the manufacturer’s stated recovery rate.
A purifier with higher recovery can potentially reduce water wastage, although actual performance depends on the incoming water conditions.
5. Calculate Long-Term Maintenance Cost
Don’t look only at the purchase price.
Also check:
- Filter replacement cost
- RO membrane cost
- Service charges
- AMC cost
- Installation charges
- Replacement frequency
A ₹18,000 purifier with expensive yearly maintenance may cost more over several years than a slightly more expensive purifier with lower maintenance costs.
6. Check Warranty
Compare the warranty carefully.
Look for:
- Comprehensive warranty
- Filter coverage
- RO membrane coverage
- Electrical-component coverage
- Installation coverage
Warranty terms vary by brand and model.
7. Check Installation Requirements
Before buying, confirm:
- Available wall space
- Water inlet connection
- Drain connection
- Electrical socket
- Water pressure
- Installation availability in your location
8. Don’t Choose Based Only on Copper or Alkaline Features
Copper and alkaline features can sound attractive, but they should not be the main reason for choosing a purifier.
First prioritize:
- Correct purification technology
- Water quality
- Filter quality
- Water recovery
- Maintenance cost
- Service availability
Then consider additional features.
