I think it's funny when people think it involves waiting... I'm usually done filtering before other people are done pumping. But to each his own.

You could always go with a Sawyer inline filter if speed is the need - splice it into the hose of the hydration bladder. Then you can fill the bladder with water straight from the source and drink through the filter. They weigh 3 oz, you could take two or three filters and swap if one clogs and you don't want to stop to backflush it.
