New Delhi, Oct. 5 -- RO, UV and UF water purifiers offer a multi-stage approach to treating Indian tap water, which can vary in quality and mineral content. RO filtration helps reduce dissolved salts, heavy metals and other impurities, while UV technology uses ultraviolet light to deactivate bacteria and viruses.

UF filtration can remove fine particles and certain microorganisms without electricity. Together, these technologies can provide cleaner, safer-tasting drinking water.

However, RO systems may waste water during filtration and can reduce some naturally occurring minerals. UV and UF also have limitations against dissolved contaminants. Regular filter replacement and servicing are essential to maintain purification performance and...
