The following is the actual results that we documented showing that the Gulf Coast Parts Washer Filter went the entire 6 months without solvent changes.  The other parts washers were being serviced every 2 weeks and had a total of 12 solvent changes in the same period.  We cannot disclose the name of this company on the Internet but you can actually see the initials from the shop manager every time the Gulf Coast Filter was changed.  The solvent in our test unit had zero solvent changes for the entire test and the mechanics were still  happy with the quality of the solvent.
