Ya craigube demonstrates those cap/filter devices but in my opinion it's more trouble than its worth: I don't mind having a little sediment in the bottom, especially since its a sign that the yeasties have done their job. Don't have to drink the sludge , just pour it out. And there are several commercial beers that have sediment. Kegs are an option, but I like having bottles. I can give them away, share, throw a few of different batches in the fridge for variety. Whatever the reason I prefer bottles. A little sediment doesn't really bother me.
And even with those cap/filter gadgets I wonder if there might still be sediment . So unless you force carb, keg, etc, sediment just feels like a necesary evil when it comes to making great beer. I guess the real question is why does it bother you? Is it becaus it looks gross? Are you drinking from the bottles and not pouring into a glass? Is there excessive sediment because you racked the beer in such a way that siphoned more sediment than normal?
