Choosing the right water purifier in Bangalore is not as simple as buying the most popular brand. Water quality in the city varies widely depending on location, source, and supply method. Borewell water, tanker water, and BWSSB supply all have different contamination levels. Understanding the difference between RO, UV, and UF purification technologies is essential to ensure your family drinks safe and healthy water.
Understanding Bangalore’s Water Quality
Most areas in Bangalore depend heavily on borewell and tanker water. These sources often contain high Total Dissolved Solids (TDS), hardness, heavy metals, and sometimes fluoride or iron. In contrast, some localities receive treated municipal water, which may have biological contamination but lower TDS.
This variation makes choosing the correct purification method extremely important.
What Is RO (Reverse Osmosis)?
RO purification works by forcing water through a semi-permeable membrane that removes dissolved salts, heavy metals, and chemical contaminants.
Best suited for:
- Borewell water
- Tanker water
- Areas with high TDS levels (above 500 ppm)
What RO removes:
- Excess salts and hardness
- Heavy metals like lead and arsenic
- Fluoride and nitrates
- Chemical impurities
Limitations:
- Wastes some water during purification
- Requires regular servicing and filter replacement
For most Bangalore homes using borewell or tanker water, RO is the most effective and safest option.
What Is UV (Ultraviolet) Purification?
UV purification uses ultraviolet light to kill bacteria, viruses, and microorganisms present in water.
Best suited for:
- Municipal or BWSSB water
- Water with low TDS (below 300 ppm)
What UV removes:
- Bacteria and viruses
- Microbial contamination
Limitations:
- Does not remove dissolved salts, metals, or chemicals
- Water must already be clear for UV to work effectively
UV alone is not suitable for most borewell-dependent areas in Bangalore.
What Is UF (Ultrafiltration)?
UF purification uses a hollow fiber membrane to physically filter out suspended particles and microorganisms.
Best suited for:
- Low TDS water
- Areas with visible dirt or turbidity
What UF removes:
- Sediments and cysts
- Some bacteria
Limitations:
- Cannot remove dissolved salts or heavy metals
- Ineffective against viruses
UF is often used as a pre-filter or combined with UV for better results.
RO vs UV vs UF: A Quick Comparison
| Technology | Removes Salts & Metals | Kills Germs | Best for Bangalore |
|---|---|---|---|
| RO | Yes | Yes (with UV/UF combo) | Highly suitable |
| UV | No | Yes | Limited use |
| UF | No | Partial | Limited use |
What Actually Works for Bangalore Water?
For most Bangalore households, especially in areas relying on borewell or tanker water, an RO-based purifier with UV and UF combination works best. This ensures:
- Removal of high TDS and chemical contaminants
- Protection against bacteria and viruses
- Better taste and safe drinking water
Homes using only municipal water may manage with UV or UV+UF systems, but periodic water testing is still recommended.
Common Mistake Bangalore Homeowners Make
Many homeowners buy UV or UF purifiers because they are cheaper, without checking water TDS. This leads to unsafe drinking water despite having a purifier installed. Always test your water before choosing a system.
