Hi Marshall, I don't know. I put one in front of my still because the TDS went way up when I put new carbon in the post-filter
My guess is that they want to catch whatever got through the still, because most domestic stills do not have a carbon pre-filter. Some stills have a pre-heat and vent cycle which drives the gases out and lets them drift away before starting the distillation cycle. Possibly they use a post-filter because there will be less stuff in the distilled water to use the binding sites in the carbon and it will therefore last longer.

It seems logical to put the carbon filter in front of the steam distiallation so as not to contaminate the water. Any idea what their reasoning is for put it post distillation?
