I'm nearing the end of a 500 ml bottle of VDB that was made up in January, and can report that it contains only a tiny amount of sediment. It's never been filtered - what's different about it is that weighing and mixing was interrupted by the call for dinner, at which point the f.a. citrate and tartaric acid solutions had been combined but the silver not yet added. This was not done until 2 or 3 hours later.
Can't promise that others will have the same result, but maybe worth trying if you have problems with sediment... ?
