From what I've researched, the temperature you need for the oven is only about 150 degrees. The boiling for about 20-30 minutes beforehand.
This is not to re-activate, which involves high temperatures in a carefully controlled reducing atmosphere. Not worth the trouble.
But the boil/oven dry will evaporate some of the volatiles from the micro and nano cracks in the carbon. I have not tried it with the EZ cartridge, but have found it works with bulk carbon method. I reckon it is only good for 1 or 2 of these processes at the most though.
Worth a try with the EZ carbon Tell us if you try again, a lot use this filter.
it is worth mentioning that the use of carbon in this way is not a traditional filter. A traditional filter allows particles of a smaller size through while trapping large ones simply due to size. The activated carbon attracts congeners and volatiles by a weak electrostatic force and holds them in the cracks. Some but not all may be released by the above method.
