Which water purifier is best for home use?

The best water purifier depends on your water source TDS level. For TDS above 500 ppm, an RO purifier is recommended. For municipal water with TDS below 500, a UV+UF purifier works well. Use our free AI Purifier Recommender to get a personalised recommendation.

How often should I change my RO filter?

RO membranes typically last 2-3 years, sediment filters every 6-12 months, carbon filters every 6-12 months, and UV lamps annually. Use our free Filter Life Predictor for exact dates based on your usage.

What TDS level is safe for drinking water?

WHO recommends drinking water TDS below 300 ppm. TDS between 300-600 ppm is acceptable. Above 1200 ppm is considered unsafe. Our AquaBot can interpret your specific TDS reading.
