1. A method for measuring downhole fluid properties, comprising:
disposing a downhole fluid sampling tool into a wellbore at a first location, wherein the downhole fluid sampling tool comprises:
at least one probe configured to fluidly connect the downhole fluid sampling tool to a formation in the wellbore;
at least one filter, wherein the at least one filter is disposed in the at least one filter section, wherein one or more flocculants are disposed in the at least one filter; and
a channel, wherein the channel fluidly connects the at least one filter section to the formation through the at least one probe; and
drawing a wellbore fluid through the at least one probe and through the channel to the at least one filter section;
filtering the wellbore fluid at the at least one filter section for forming a filtered wellbore fluid;
sending the filtered wellbore fluid to the wellbore through the channel; and
measuring a property of the filtered wellbore fluid.
