RO system tweak/upgrade, muddy water

[bevenz]

Hi,
I have a Customised RO installed a couple of years back with a tank and tap. All was well till February this year when the water in my society in Gurgaon turned really muddy. Now I am forced to change my pre-filter every 15-20 days and changed my sediment and carbon in 3 months. Is there some solution as to what I can use to make the prefilter last at least a month!?!

Unfortunately, I don't think there is any solution that, as "Pre-filter" itself is the solution to this issue.

A repair guy suggested using 0.1 micron MF filter, said it helps with turbidity more than PP 5 micron filter, need to confirm because it costs 10 times a PP filter.
