RO vs UV vs UF — What You Actually Need

RO (Reverse Osmosis): Removes dissolved solids, heavy metals, salts. Necessary if TDS > 300 ppm.
UV (Ultraviolet): Kills bacteria and viruses. Essential for safety.
UF (Ultrafiltration): Removes suspended particles, cysts, bacteria. Doesn't reduce TDS.
Best combo: RO + UV + TDS controller — handles every water source.

TDS Level — The Deciding Factor

Check your input water TDS with a meter (free on Amazon for ~₹200). Below 300 = UV-only is fine. 300-600 = RO needed. Above 600 = RO mandatory. Borewell/tanker water usually needs RO. Municipal supply can get away with UV+UF.

Storage Capacity for Families

7L = 2-3 person household. 8-10L = 4-6 person. Large families or offices need 10L+.

FAQ

Q1. Do I really need RO if municipal water tastes fine?

Yes — bacteria, viruses, and TDS are tasteless. Test water first; TDS >300 needs RO regardless of taste.

Q2. What's the difference between RO and UV?

RO removes dissolved solids/salts; UV kills bacteria/viruses. You need both for complete protection.

Q3. How often do filters need replacing?

Pre-filters: every 3-6 months. RO membrane: 1-2 years. UV lamp: 2 years. Kent/Pureit remind you via indicator.

Q4. Is RO water safe for daily drinking?

Yes — TDS controller keeps minerals at 50-150 ppm, which is safe. Don't use RO without TDS control.

Q5. Which is better — Kent or Pureit?

Kent has better service network and RO tech; Pureit offers more features per rupee. Both are reliable.

Q6. Can it handle borewell water?

Yes — all RO models handle high TDS borewell water. Check your TDS first to confirm RO is needed.

Q7. What's the installation cost?

Free — Amazon includes brand installation for all models above ₹5000.

Q8. How much water does an RO waste?

Traditional RO: 1-3L wasted per 1L purified. Kent/Pureit water-saving models: ~1L wasted per 1L purified.

Q9. Best purifier for a family of 4?

Kent Marvel (8L) or Pureit Eco Saver (10L) — both handle daily drinking + cooking water.

Q10. Do I need a pre-filter?

If your water has visible sediment or sand — yes. Most models include one; replace every 3-6 months.
