I just replaced my Kent DI Mixed Cartridge after 6 months of use (I felt this was the appropriate time to replace). I have the Kent Maxxima (50 GPD RO/DI System - 4 stage) It took me all of 5 minutes to replace this cartridge. For maintenance, I change the lower 3 cartridges at the same time, run about 10 gallons through it (to remove the carbon), dump this water and you are good to go!
