RO, UV, and UF have their own benefits. Considering only a single technology is not right, because each technology targets different types of impurities. The suitable option among the three depends on the water quality and contamination. Some purifiers offer all three technologies in it, which can address multiple purification needs. That is why it is important to check the water source and TDS level before purchasing a water purifier.

• RO Water Purifier: RO technology helps in removing dissolved salts, excess TDS, and heavy metals. It is useful for areas where water has more dissolved impurities.
• UV Water Purifier: UV technology is helpful in removing bacteria and viruses using ultraviolet light. It is useful in treating water with microbial contamination.
• UF Water Purifier: UF technology helps in filtering suspended particles and certain microorganisms with the help of a fine membrane. But it does not remove dissolved salts and TDS effectively.
