I guess I don't understand why you filter in the first place. Why not just use gelatin? or if you are fermenting in a corny for the primary, why not just cut off the dip tube or add some hose to the end of the dip tube angled up so it doesn't pick up the trub in the first place? Not trying to marsh your mellow .. I'm a big fan of DIY'edness and think your filter is pretty awesome.
