What's the best portable water filter bottle?

Filtrete has a new product it's a water bottle filling station. The unit has a fast flow carbon filter that fills docked water bottles that seal and you can take with you, then come home and fill them again. It's only about $35 too. a href="http://truthofwater.com/answers/2011/06/03/water-bottle-docking-station/" rel="nofollow"http://truthofwater.com/answers/2011/06/…/a
