Frequently Asked Questions
Quick answers to the most common questions about water purification
Q: Which is the best water purifier for home use in India?
A: The best purifier depends on your water source and TDS level. RO+UV purifiers are ideal for areas with high TDS (above 500 ppm). Check our detailed buying guide for brand-specific recommendations.
Q: How often should I change RO membrane filters?
A: RO membranes typically last 2–3 years with normal use. Pre-filters (sediment and carbon) should be replaced every 6–12 months. Regular TDS testing will help you track filter performance.
Q: What is a safe TDS level for drinking water?
A: The WHO recommends drinking water with TDS below 300 ppm for best taste and health. Water between 300–500 ppm is acceptable. Above 500 ppm may require RO purification. Below 50 ppm lacks essential minerals.
Q: Is RO water safe for drinking every day?
A: Yes, RO water is safe for daily consumption when the purifier includes a mineral-adding stage. Most modern RO purifiers have TDS controllers and mineral cartridges to restore beneficial minerals removed during filtration.
