What Is RO, UV, UF & TDS in Water Purifiers?
Most water purifiers just use the fancy jargon “RO+UV+UF+TDS filtration” but what relevance does these filters hold in purifying water? The following explanation by experts would help you get a better clarity of these terms and the products table will match you with the exact kind of filtrations you are looking for in one water purifier.
-
RO (Reverse Osmosis)
Uses high pressure to push water through a membrane that acts like a super-fine filter. It’s the only system that removes heavy metals and dissolved salts (TDS), making it essential for hard or salty water.
Best for: Borewell or tanker water with TDS over 500 ppm.
-
UV (Ultraviolet)
Uses a powerful light to deactivate germs like bacteria and viruses, making them harmless. It doesn't change the taste or remove chemicals, but it ensures the water is biologically safe.
Best for: Municipal water that is already soft but might be contaminated.
-
UF (Ultrafiltration)
Uses a physical mesh to trap dirt, dust, and bacteria without needing electricity. It works like a microscopic sieve, keeping the water clear and germ-free while leaving all minerals intact.
Best for: Low-TDS water in areas with frequent power cuts or for basic dirt removal.
-
TDS Controller
Since RO can strip away good minerals along with the bad, this feature adds them back or blends water to restore taste and health benefits. It prevents the water from tasting flat or being too acidic.
Best for: Maintaining mineral balance and better flavor in any RO system.
