1st Stage: Pre Filter- The water main is fed directly to the 5 micron filter where all the particles, 5 micron and more than that are removed2nd Stage: Sediment Filter- Removes sediment particles like suspending dirt, sand and rust3rd Stage: Pre Carbon Filter- Easily absorbs chlorine, methane, removes color and bad taste by carbon effective adsorbability4th Stage: RO Membrane- High rejection (95-99%) thin film composite R.O. membrane for rejecting wide spectrum of impurities including Total Dissolved Solids (TDS), bacteria and viruses down to 0.0001 micron5th Stage: Post Carbon Filter- Removes the bad taste and adsorbing chemical that presents in the water and adds taste to the water
