It is the second water filtering process which plays an important role in removing dirt particles and making the water pure .

Stage 4: UDF Filter (Box Carbon Filter) – A UDF filter, also known as a box carbon filter or activated carbon filter, is a device used to remove impurities and pollutants and other bad chemicals from water and make water 99% pure.

Stage 5: RO Membrane Filter – RO Membrane plays the most important role in this entire filtering process. RO Membrane removes various ions, salts, bacteria, viruses dissolved in water and makes water suitable for drinking. The RO membrane filter life time is 1 year. That is, the RO membrane filter should be changed every twelve months. But it depends on the water quality.
