Clean and healthy drinking water is the foundation of a healthy life. In cities like Pune, people get different types of water—borewell, tanker, or corporation supply. Each type of water contains different kinds of impurities such as dust, mud, bacteria, viruses, hard salts, chemicals, and high TDS. Because of this, choosing the correct water purifier is very important. Many people feel confused between RO, UV, and UF systems. To help you understand clearly, Aqua Penta Filter brings you this simple and complete guide.

⭐ 1. RO (Reverse Osmosis) – Best for Borewell & High-TDS Water

RO is the most advanced and powerful purification technology. In RO, water passes through a special membrane with tiny pores (0.0001 micron). This membrane removes almost every harmful element from the water.

✔ RO is required when:

• Your home receives borewell water
• Water has TDS above 400
• Water tastes salty
• Water has hardness or iron
• You use tanker water of unknown quality

✔ Benefits of RO:

• Reduces TDS by 95%
• Removes salts, heavy metals, chemicals
• Improves taste of water
• Safe for drinking and cooking
• Best long-term protection for kidney and stomach

✘ When RO is not needed:

• When water has low TDS (50–250)
• When water is corporation / municipal supply

If you use RO for very low TDS water, it removes natural minerals unnecessarily.

⭐ 2. UV (Ultraviolet) – Best for Municipal Water

UV purification uses ultraviolet light to kill germs, bacteria, and viruses. This method does not reduce TDS or remove minerals, but it makes water microbiologically safe.

✔ UV is suitable for:

• Municipal / corporation water
• Low TDS water (below 250)
• Homes where water is clear but needs germ protection

✔ Benefits of UV:

• Kills bacteria and viruses instantly
• Keeps natural minerals in water
• No change in taste
• Low maintenance
• Affordable price

✘ Limitations:

• Does not remove dust or mud
• Does not reduce TDS
• Not for borewell water

If your water is treated but you only want to kill germs, UV is the perfect choice.

⭐ 3. UF (Ultrafiltration) – Best Without Electricity

UF uses a membrane of 0.01 micron. It removes dust, sand, mud, and some bacteria. UF is ideal for clean water that has small physical impurities.

✔ UF is best for:

• Corporation water
• Low TDS (50–200)
• Homes where RO is not needed
• Areas with frequent power cuts

✔ Benefits:

• Can work without electricity
• Removes dust and mud
• Keeps natural minerals
• Very low maintenance
• Budget-friendly

✘ Limitations:

• Cannot remove high TDS
• Cannot remove salts or chemicals
• Not suitable for borewell water

⭐ Quick Comparison Table

⭐ How to Choose the Best Purifier for Your Home?

Choosing the right purifier becomes easy if you know your water type.

✔ If you have borewell water → Choose RO

Because borewell water has high TDS, salt, hardness, and chemicals.

✔ If you get municipal/corporation water → Choose UV + UF

This gives two benefits:

1. Germ protection (UV)
2. Dust removal (UF)

✔ If you get tanker water → Choose RO or RO + UV

Tanker water changes daily, so RO is safest.

✔ If you have low TDS and only dust → Choose UF

Cheapest and best natural purification.

⭐ Final Conclusion

There is no single purifier that is perfect for everyone. The correct purifier depends on your water source and TDS level.

• RO is best for borewell and high-TDS water.
• UV + UF is best for corporation water.
• UF alone is suitable for low-TDS water with minor dust.

Choosing the right technology ensures safe water, better health, and lower maintenance cost.
