OK, so here's the thing: you can't filter chlorine.
You can't. It's an ion. It's really freaking tiny. 1.81 angstroms tiny. That's 0.000181 microns.
A filter that removes chlorine does so by adsorbing it on activated charcoal. So if you have a filter that contains charcoal, (almost all water filters do, it's what allows them to say "removes chlorine"), then you will remove chlorine, REGARDLESS of the micron rating of the filter.
Micron ratings are for removing sediment, unflocculated crap that causes turbidity, (cloudiness), and protozoan cysts and bacteria.
