The AI answer we saw
The choice between RO and UV depends primarily on your water's TDS level and contamination type. For municipal tap water with TDS below 300 ppm and no heavy metal contamination, a UV purifier is generally sufficient—it effectively kills bacteria and viruses without removing beneficial minerals. If your TDS is above 300–500 ppm or the water has dissolved impurities like chlorine, fluoride, or heavy metals, an RO purifier is more appropriate. A combined RO+UV system offers comprehensive purification and is a safe choice if you are unsure of your water quality. It is advisable to get your tap water tested before deciding.
