Top 10 Questions and Answers on Water Purifiers
1. Which type of water purifier is best for home use?
Answer: The best type of water purifier depends on the quality of water in your area. If your water has high TDS (Total Dissolved Solids), an RO (Reverse Osmosis) purifier is ideal. If the water has bacterial contamination, a UV (Ultraviolet) purifier is recommended. UF (Ultrafiltration) purifiers work best for water with low TDS and no dissolved impurities. Some advanced purifiers combine RO, UV, and UF for better purification.
2. What is the difference between RO, UV, and UF water purifiers?
Answer:
- RO (Reverse Osmosis): Removes dissolved salts, heavy metals, and contaminants. Suitable for high TDS water.
- UV (Ultraviolet): Kills bacteria and viruses but does not remove dissolved solids. Ideal for municipal water.
- UF (Ultrafiltration): Filters bacteria and sediments without electricity but doesn’t remove dissolved impurities. Best for low-TDS water.
3. How often should I change the filters in my water purifier?
Answer: It depends on usage and water quality. Generally:
- Sediment and Carbon Filters: Every 6–12 months
- RO Membrane: Every 2–3 years (or sooner if TDS levels are high)
- UV Lamp: Every 1 year
- UF Membrane: Every 1–2 years
4. Does an RO water purifier remove essential minerals from water?
Answer: Yes, RO purifiers remove essential minerals along with contaminants. However, many modern RO purifiers have mineral retention technology or TDS controllers that restore essential minerals like calcium and magnesium to maintain water quality.
5. What is TDS in water, and why is it important?
Answer: TDS (Total Dissolved Solids) represents the concentration of dissolved minerals, salts, and metals in water.
- Ideal TDS for Drinking Water: 50–150 ppm
- Moderate TDS: 150–500 ppm (Safe for consumption)
- High TDS (>500 ppm): Requires RO purification
High TDS can make water taste salty and may contain harmful chemicals.
6. How do I know if my water purifier is working properly?
Answer: Signs that your water purifier is not working efficiently include:
- Bad taste or odor in water
- Reduced water flow
- TDS levels not changing after filtration
- Warning indicators on the purifier (if applicable)
Regular maintenance and TDS checks ensure the purifier is functioning correctly.
7. What is the average lifespan of an RO membrane?
Answer: The lifespan of an RO membrane depends on water quality and usage. On average, it lasts 2–3 years. If the input water has high TDS and contaminants, it may need replacement sooner. Regular cleaning and timely filter replacements help extend its lifespan.
8. How do I maintain my water purifier for long-lasting performance?
Answer:
- Change pre-filters on time to protect the RO membrane.
- Clean storage tanks periodically.
- Check water pressure to ensure optimal functioning.
- Get professional servicing every 6–12 months.
- Test TDS levels regularly to monitor water quality.
9. Can I use a water purifier if my water source has high hardness?
Answer: Yes, but RO purifiers are the best choice for hard water. They remove excess calcium and magnesium, reducing water hardness. If the hardness is extremely high, using a water softener before the RO system can improve performance.
10. What should I consider before buying a water purifier?
Answer:
- Water Quality: Test TDS levels and check for bacterial contamination.
- Purification Technology: Choose RO, UV, or UF based on water quality.
- Storage Capacity: Ensure sufficient storage for household needs.
- Maintenance Cost: Look for a purifier with affordable filter replacements.
- Brand and Warranty: Choose a reliable brand with good after-sales service.😊
