Choosing the right water purifier can be confusing with so many options available. This complete guide will help you make the best decision for your family's health.
Types of Water Purifiers
1. RO (Reverse Osmosis) Purifier
Best for high TDS water (above 300 ppm). Removes dissolved salts, heavy metals, bacteria, and viruses. The most popular type in India.
2. UV Purifier
Best for low TDS water. Kills bacteria and viruses but does NOT remove dissolved salts and chemicals. Good for municipalities with treated water.
3. UF (Ultrafiltration) Purifier
Works without electricity. Removes bacteria and cysts but not dissolved chemicals. Good backup option.
4. Alkaline RO Purifier
The BEST option — combines RO purification with mineral addition to make water alkaline. Removes all impurities AND makes water healthy.
How to Choose Based on TDS
- TDS below 200 ppm: UV or UF purifier sufficient
- TDS 200–400 ppm: RO purifier recommended
- TDS above 400 ppm: Alkaline RO purifier strongly recommended
Key Features to Look For
- Multi-stage purification (8–12 stages is ideal)
- Storage capacity (7–10 litres for family of 4)
- Purification speed (8–15 litres/hour)
- Warranty (minimum 1 year)
- After-sales service availability in your city
Alkin Recommendation: For most Indian homes with TDS above 300 ppm, the Alkin Alkaline RO Purifier (10-stage) is the ideal choice — it purifies, mineralizes, and alkalizes your water.
