The pore size of the RO Membrane is 0. 0001 micron. It reduces hardness, TDS, heavy metal contaminants including arsenic, lead, and mercury, as well as harmful microorganisms, making the water chemically and microbiologically drinkable.
UV systems kill 99.99% of hazardous microbes without adding chemicals or altering the taste or odor of your water.
Ultrafiltration (UF) removes pollutants by forcing water through a semipermeable membrane using normal household water pressure.
Rigo institutional water filter comes with different combinations of RO/UV.
