Technology. The industrial revolution, the auto, the tv, the computer, the smart phone... the Vortex Funnel.
You too can now be an early adopter and enjoy fast transferring. But wait... there's more. With the optional filter paper (BE481) you can also eliminate large chunks of material that typically give unwanted fiber to your drinks.
On a somewhat more serious note, filter paper can be handy for filtering oak, spices, and fruit out of wine, fruit wine, specialty beers, liquors, etc.. Buy the funnel because you need a ingeniously designed funnel and then you have the ability to use the optional filter paper when that special circumstance arises.
