I don't think it will work for you. I have set up several aquariums and when you first fill them the fine particles in the gravel (I am salt water and use crushed coral/rock) gets mixed up in the water and all the filtering in the world does little to help clear the water. Time and settling is what clears it up. I think the suspended sediment in my start up aquariums is quite like the suspended sediment in beer. It is so, so fine filtering would take more time and effort than I think it would be worth. I don't think an hour is going to do much to clear your beer if that is what you are going for. If you are talking about what floats on top that filter will do nothing for that either.
That said, you are talking about post fermentation right? Well, by the time you get any results I think you will have exposed the beer to way too much open air exposure for its good. If you do try it I would use the filter medium AND the charcoal too and report back if you are happy with the results.
