Borewell water is a common source of drinking water in many households across India. However, it often contains high levels of total dissolved solids (TDS), heavy metals, bacteria, and hardness, making it unsafe for direct consumption. A high-quality water purifier is essential to ensure safe and clean drinking water. This guide will help you choose the best water purifiers for borewell water based on key factors such as purification technology, water quality, and maintenance requirements.
Understanding Borewell Water Quality
Before choosing a water purifier, it is crucial to analyze the quality of your borewell water. Common impurities found in borewell water include:
- High TDS levels: Contains dissolved salts and minerals, making water hard.
- Heavy metals: Presence of arsenic, lead, iron, and mercury can be harmful.
- Bacterial contamination: Microbes such as E. coli and viruses may be present.
- Excessive hardness: Calcium and magnesium levels may cause scaling in pipes and appliances.
A TDS meter can help determine the level of dissolved solids in the water. If the TDS level exceeds 500 ppm, a Reverse Osmosis (RO) purifier is recommended.
Types of Water Purifiers for Borewell Water
1. Reverse Osmosis (RO) Purifiers
RO water purifiers are ideal for treating borewell water with high TDS. They use a semi-permeable membrane to remove dissolved salts, heavy metals, and harmful chemicals. Features to look for in an RO purifier:
- TDS controller or mineralizer to retain essential minerals
- Multi-stage purification (RO+UV+UF) for enhanced water safety
- Large storage capacity for uninterrupted supply
2. Ultraviolet (UV) Purifiers
UV purifiers use ultraviolet rays to kill bacteria and viruses without removing essential minerals. However, they are not effective in reducing TDS or heavy metals. UV purification is suitable when borewell water has microbiological contamination but a low TDS level.
3. Ultrafiltration (UF) Purifiers
UF purifiers use a membrane to remove bacteria, cysts, and sediments. They work well for mildly contaminated water but do not remove dissolved salts. Combining UF with RO or UV enhances purification.
4. RO+UV+UF+TDS Controller Purifiers
For comprehensive water purification, a combination of RO, UV, and UF technologies with a TDS controller is recommended. This system ensures:
- Removal of heavy metals and salts
- Elimination of bacteria and viruses
- Retention of essential minerals for healthy drinking water
Factors to Consider When Buying a Borewell Water Purifier
1. TDS Level and Water Quality
Check your water’s TDS level before selecting a purifier. If it is above 500 ppm, opt for an RO-based purifier. If the TDS is below 300 ppm, UV or UF purifiers are sufficient.
2. Storage Capacity
Choose a purifier with a suitable storage capacity based on your household’s daily water consumption. A 7-10 liter storage tank is ideal for a medium-sized family.
3. Purification Stages
Multi-stage purifiers (RO+UV+UF) provide better protection by eliminating all types of contaminants. Additional features like a TDS controller help retain essential minerals.
4. Filter Replacement and Maintenance
Regular maintenance is necessary to keep your purifier functioning effectively. Consider models with easy-to-replace filters and indicator alerts for timely servicing.
5. Energy Consumption and Waste Water Management
RO purifiers generate wastewater during purification. Opt for models with water-saving technology or a reject water tank to minimize wastage.

Conclusion
Selecting the best water purifier for borewell water depends on the quality of water and the specific contaminants present. RO purifiers are the most effective for high TDS water, while UV and UF purifiers work well for microbiologically contaminated water with low TDS. A combination of RO+UV+UF with a TDS controller is the best choice for comprehensive purification. Investing in a high-quality water purifier ensures safe, clean, and healthy drinking water for you and your family.
