Time to replace the filters. Should I replace with the same as it came with (TFC membrane, 1 micron micro tech, carbon block and DI color changing resin), or change to a different line up. Water going in is around 30 TDS. Thanks

what is the water coming out, and how long has it been since you either replaced last or purchased the unit? How many gallons have been made?
