🔬 How to Select Based on Water TDS Level
- Below 250 ppm (Municipal Tap Water): Buy a UV+UF purifier. RO is not required and strips healthy natural minerals.
- 300 to 1,500 ppm (Tanker & Groundwater): Buy an RO+UV purifier with a TDS controller (e.g., Kent Grand or Aquaguard Delight).
- Above 1,500 ppm (Heavy Borewell Water): Choose heavy-duty high-pressure RO purifiers like Urban Company Native M2 or HUL Pureit Eco.
🛡️ How to Identify Original vs Fake Water Purifier Filters in India
- Always Verify Amazon Seller: Purchase directly from official brand stores (e.g., “Sold by Appario Retail” or official “Kent RO Systems Ltd” / “Eureka Forbes Ltd” stores).
- Check the 3D Hologram: Genuine Kent, Aquaguard, and Pureit cartridges carry tamper-evident laser holograms.
- Match QR Code Serial Numbers: Scan the QR code on the cartridge wrapper via the brand app to verify serial registration.
- Insist on GST Invoice: Genuine warranty claims are valid only when backed by an authorized GST invoice matching the serial number.
Frequently Asked Questions (FAQs)
1. What TDS level requires an RO water purifier?
If your source water has TDS above 300 ppm (common in borewells and tanker supplies), an RO (Reverse Osmosis) purifier is necessary to remove heavy metals and excess salts. If TDS is below 250 ppm (treated municipal corporation water), a UV+UF purifier is sufficient.
2. How much electricity does an RO purifier consume per month?
A typical home RO purifier consumes between 35W to 60W per hour during operation. For an average family of 4, the purifier runs roughly 1–2 hours daily, adding less than ₹20 to ₹35 to your monthly electricity bill.
3. How often should water purifier filters be changed?
Sediment and carbon pre-filters should be replaced every 6 to 12 months. RO membranes typically last 18 to 24 months depending on incoming water hardness. Models like the Urban Company Native M2 feature 2-year extended filter cycles.
