Clean drinking water is essential for a healthy lifestyle, and choosing the right water purification method is critical to achieving this goal. Ultrafiltration (UF) is a modern technology that ensures safe and clean water for households. This is useful for those areas with low Total Dissolved Solids (TDS) levels. This membrane-based purification process removes bacteria, viruses, and suspended particles while retaining essential minerals. If you are looking for an eco-friendly and chemical-free solution, ultrafiltration is worth considering. 


Getting a new water purifier is now budget-friendly. Simply browse the selection of water purifiers on Bajaj Mall. Alternatively, visit any of Bajaj Finserv’s 1.5 lakh partner stores in 4,000 cities in India. Choose the product that you like and get Easy EMI and zero down payment offers exclusively with Bajaj Finserv’s financing options. Check your loan eligibility and convert the cost of your new water purifier into Easy EMIs.

Overview of the ultrafiltration process

Ultrafiltration works by passing water through a semi-permeable membrane under pressure. This membrane is designed to filter out contaminants such as bacteria, viruses, and suspended particles, ensuring the water is safe for drinking. Unlike other purification methods, UF retains healthy minerals, making it an ideal choice for homes that rely on low TDS water sources. Additionally, ultrafiltration is an energy-efficient and environmentally friendly solution, as it does not require electricity for the core purification process.

What water is best for UF?

Ultrafiltration is most effective for water sources with low TDS levels, such as municipal water supplies. It is not suitable for high TDS water, as it does not remove dissolved salts or heavy metals. For households with TDS levels below 300 ppm, UF offers a sustainable and chemical-free purification method. This makes it a popular choice for eco-conscious consumers looking for a reliable way to ensure safe drinking water.

Does UF require electricity?

One of the significant advantages of ultrafiltration is that it does not require electricity for the primary purification process. The system relies on pressure to push water through the semi-permeable membrane, making it an energy-efficient option. However, certain advanced features, such as automated sensors or water dispensing mechanisms, may require electricity. This makes UF a cost-effective and environmentally friendly choice for households aiming to reduce their energy consumption.

When is ultrafiltration the ideal purification method?

Ultrafiltration is a versatile and efficient water purification method. Here are some ideal scenarios where UF is the best choice:

  • Municipal water with low TDS: UF is perfect for homes that rely on treated municipal water with TDS levels below 300 ppm.
  • Eco-conscious households: If you prioritise sustainability and want a chemical-free purification solution, UF is an excellent option.
  • Non-electric purification needs: UF is ideal for rural or urban areas where electricity supply may be inconsistent or unavailable.
  • Low-maintenance purification: UF systems are easy to maintain and do not require frequent filter replacements, making them cost-effective in the long run.

What is the ultrafiltration process in purifiers?

Ultrafiltration purifies water by pushing it through a semi-permeable membrane using pressure.

  • It removes bacteria, viruses, and suspended solids but retains essential minerals, making water safe for drinking.
  • UF is eco-friendly and ideal for low TDS water sources.
How does UF differ from RO and UV?

Ultrafiltration removes harmful microorganisms without electricity and retains minerals, unlike RO. RO uses reverse osmosis to remove chemicals and desalinate high-TDS water. UV requires electricity to kill microorganisms but cannot remove salts or metals. Choose UF for low TDS, RO for high TDS, and UV for sterilisation needs.

Does UF require electricity?

No, UF purifiers do not need electricity for core purification as they rely on pressure. However, automated dispensing or sensor-enabled features may require electricity. UF ensures affordable and power-efficient purification for low TDS water sources.
