A method comprising:

• disposing a downhole fluid sampling tool into wellbore, wherein the downhole fluid sampling tool comprises:
• a tool body;
• a flow port disposed on the tool body;
• a sample chamber disposed within the tool body and fluidly coupled to the flow port;
• a pump disposed within the tool body, wherein the pump is configured to pump a fluid through the flow port into the sample chamber;
• a filter disposed on an inlet of the flow port, wherein the filter is configured to filter the fluid entering the flow port;
• and
• a removable filter cover configured to prevent fluid contact with the filter;
• removing the removable filter cover from the filter;
• and
• filtering at least a portion of the engineered fluid pill using the filter.
